  • SEC Climate Rollback Won’t Free US Multinationals

    The headlines are tempting: the SEC is moving to scrap the climate-disclosure rules it adopted in 2024, and some commentators have read that as the end of mandatory climate reporting for US companies. For any business with revenue in California or operations in Europe, the opposite is closer to the truth. The federal rule was only ever one of several overlapping regimes — and the others are advancing, not retreating.

    If your reporting plan hinges on the SEC standing down, this is the moment to stress-test it. Below is what is actually happening in Washington, why it changes less than it appears to, and what reporting teams should do while the noise settles.

    What the SEC is actually doing

    On 3 June 2026, the SEC’s proposed rescission of its 2024 climate-related disclosure rules was published in the Federal Register, opening a comment period that runs through 3 August 2026. Two points are easy to miss in the headlines. First, this is a proposal in its comment window, not a settled outcome. Second, the plan is to eliminate the dedicated framework rather than replace it — reverting issuers to principles-based, materiality-focused disclosure under existing securities law. The Commission has pointed to compliance savings of roughly $4.9bn a year.

    Removing a prescriptive rulebook is not the same as removing the obligation to disclose. Material climate risks that affect a reasonable investor’s decision can still require disclosure under long-standing materiality principles. What changes is the how and the how much — not the underlying duty. And for most multinationals, the SEC was never the binding constraint anyway.

    Why “no SEC rule” doesn’t mean “no disclosure”

    Three other regimes keep mandatory climate and greenhouse-gas disclosure firmly alive for US companies of any size that trade across state or national borders. None of them depend on the SEC.

    California: the de facto US standard

    California’s climate-disclosure laws reach far beyond the state’s borders because they apply to companies “doing business in California,” regardless of where they are headquartered. Two statutes matter:

    • SB 253 (Climate Corporate Data Accountability Act) requires companies with total annual revenues above $1bn to report Scope 1, Scope 2 and, in a later phase, Scope 3 greenhouse-gas emissions.
    • SB 261 (Climate-Related Financial Risk Act) requires companies with revenues above $500m to publish a climate-related financial-risk report aligned with the TCFD recommendations.

    Because the revenue thresholds are low relative to the size of a typical multinational, the practical effect is that a large share of US companies that would have reported to the SEC are captured by California instead — and California explicitly requires Scope 3, which the federal approach was always more cautious about. For most large filers, the toughest disclosure bar in the US now sits in Sacramento, not at the SEC.

    The EU: CSRD reaches across the Atlantic

    The EU’s Corporate Sustainability Reporting Directive pulls in non-EU groups through their European operations. A US parent with substantial EU subsidiaries or branches can fall directly within scope, and even companies that sit outside mandatory scope routinely receive value-chain data requests from European customers who need the numbers for their own ESRS reports. The recent “Omnibus” simplification narrowed who must report at the top of the chain, but it did not switch off the demand for emissions and sustainability data flowing down global supply chains.

    In other words, even a US company with no EU listing can find itself assembling ESRS-grade data because a major European buyer asks for it. If you sell into Europe, CSRD is part of your reality whether or not your own name is on a filing.

    The UK: anti-greenwashing and SDR

    For US groups with UK-regulated financial arms, the FCA’s Sustainability Disclosure Requirements regime adds a third layer. Its anti-greenwashing rule applies to all FCA-authorised firms, and from 30 June 2026 the remaining in-scope asset managers above £5bn in assets must publish entity-level disclosures. The throughline is consistent: any claim you make about sustainability has to be substantiated, and the supporting data has to exist.

    Fragmentation, not freedom

    The real consequence of the SEC’s retreat is not less work — it is less harmonisation. A single US-federal climate rule would at least have given multinationals one reference point that broadly tracked the global ISSB and EU baselines. Without it, a company can find itself reconciling California’s emissions thresholds, the EU’s double-materiality model, and the UK’s disclosure expectations, each with its own scope, boundary and timing.

    That is an argument for building disclosure on a single, well-governed dataset rather than chasing each regime with a separate project. The metrics underneath — Scope 1, 2 and 3 emissions, climate risk, governance and targets — overlap heavily. The expensive mistake is collecting them three times.

    What reporting teams should do now

    • Map your real obligations, not the federal one. Test your revenue and operations against California’s SB 253 and SB 261 thresholds and against EU value-chain exposure before assuming the SEC change lets you scale back.
    • Keep your GHG inventory live. Scope 1, 2 and 3 data feeds California, CSRD and customer requests alike, so a robust carbon accounting foundation is the one investment that pays off under every regime.
    • Build once, report many times. Structure your data so a single source can be mapped to multiple frameworks rather than rebuilt for each.
    • Watch the comment window, but don’t wait on it. The SEC proposal closes for comment on 3 August 2026; nothing about that date pauses California or Europe.

    The companies that handle this period well will be the ones that treated the SEC rule as one input among several, not the keystone. The disclosure expectation has not gone away — it has simply spread out, and it now rewards teams with clean, reusable data more than ever.

  • ESRS 2.0: Should You Early-Adopt for FY2026?

    For two years, CSRD preparers have built data pipelines, mapped value chains, and wrestled with more than a thousand ESRS datapoints. That groundwork is about to shift. The European Commission is expected to adopt a simplified set of European Sustainability Reporting Standards - informally “ESRS 2.0” - by delegated act in late June or early July 2026, following a public consultation that closed on 3 June. EFRAG’s advice cuts mandatory datapoints by roughly 61% and removes voluntary datapoints altogether.

    Crucially, the revised standards allow voluntary early adoption from financial year 2026, becoming mandatory only for financial years beginning on or after 1 January 2027. That leaves teams with a genuine decision to make now: keep building to the old standard, or pivot to the lighter regime a year early? This guide walks through what is changing and how to weigh the choice with clarity rather than guesswork.

    What ESRS 2.0 actually changes

    The revision is a simplification exercise, not a rewrite of the directive. Three changes matter most for reporting teams:

    • A ~61% cut in mandatory datapoints, with all voluntary datapoints removed. The aim is to concentrate disclosure on what is decision-useful and drop the long tail of marginal metrics.
    • A “top-down” approach to materiality. Rather than testing each datapoint from the bottom up, teams start from the sustainability matters that are material to the business and work down to the disclosures that follow - reducing the assessment burden that has dominated first-cycle projects.
    • Fair presentation applied to the statement as a whole, rather than to each individual datapoint. This is a meaningful audit and governance shift: the question becomes whether the report as a whole gives a true and fair view, not whether every line item is independently perfect.

    The companion Voluntary SME standard (VSME) is on the same adoption track. It underpins the “value-chain cap,” which limits what CSRD reporters can demand from counterparties with 1,000 or fewer employees - directly relevant if your Scope 3 and supply-chain data depend on smaller suppliers.

    The timeline you are actually working against

    Two dates frame the decision. After the Commission adopts the delegated act, a scrutiny period of up to four months by the European Parliament and Council must conclude before the standards are published in the Official Journal. So while the substance is effectively settled, formal finality arrives later in 2026. Early adoption applies from FY2026; mandatory application begins for financial years starting on or after 1 January 2027.

    This sits on top of the February 2026 Omnibus changes, which narrowed mandatory scope to companies with more than 1,000 employees and more than €450m turnover. Many mid-caps that were preparing to report are now outside mandatory scope entirely - yet still face value-chain data requests from larger customers. If that is you, the early-adoption question is less “must we?” and more “what is the most efficient basis to respond on?” For the fuller picture, see our CSRD timeline for 2025-2028.

    The case for early-adopting ESRS 2.0 for FY2026

    • You report on the lighter regime sooner. If your first mandatory report is FY2027 anyway, early adoption lets your FY2026 disclosure - voluntary or value-chain-driven - use the reduced datapoint set rather than the legacy one.
    • You avoid building data flows you are about to retire. Continuing to engineer collection for datapoints that the revision deletes is sunk cost. Pausing those builds now protects budget and analyst time.
    • Top-down materiality is cheaper to run. Re-scoping your materiality assessment around the new model can shrink the single most expensive part of a first cycle.
    • You signal maturity. A clean, focused report aligned to the final standards reads better to investors and assurance providers than an over-stuffed one built to a superseded draft.

    The case for waiting

    • The act is not yet final. Until the scrutiny period concludes and the text is published in the Official Journal, detail can still move. Building to a near-final draft carries some rework risk.
    • Mid-cycle re-scoping has its own cost. If you are deep into an old-ESRS data build with assurance lined up, switching frameworks mid-stream can create more disruption than it saves.
    • Comparability gaps. Reporting on a different basis from peers for one year can complicate year-on-year and benchmark comparisons until everyone converges in FY2027.
    • Internal readiness. Top-down materiality is conceptually simpler but demands confident judgement about what is material. Teams that built bottom-up muscle memory may need time to adjust.

    How to decide: a practical filter

    Work through four questions in order:

    1. When is your first mandatory report? If FY2027, early adoption mainly affects voluntary or value-chain disclosure in FY2026 - lower stakes, easier to trial. If you are still in mandatory scope for FY2026, the calculus is sharper.
    2. How far is your data build? Early-stage projects can pivot to the reduced set cheaply. Near-complete builds with assurance booked may be better finished as planned.
    3. How exposed are you to value-chain requests? If larger customers are asking for data, aligning early to the final standards - and the VSME value-chain cap - can simplify what you owe them.
    4. Can your assurance provider support it? Confirm they are comfortable giving assurance on an early-adopted basis before you commit. The new statement-level fair-presentation model is worth discussing with them directly.

    Whichever way you lean, the foundational work does not change: a defensible double materiality assessment still anchors the report, and your underlying data still needs to be traceable and audit-ready. For a fuller walkthrough of the standards themselves, see our complete ESRS reporting guide.

    The bottom line

    ESRS 2.0 is the most consequential operational change for CSRD preparers since the directive itself. For most teams whose first mandatory report is FY2027 - and especially those early in their data build or responding to value-chain requests - early adoption is the more efficient path, provided your assurance provider is on board. Teams deep into a near-complete old-ESRS cycle have a stronger case to finish as planned and converge in FY2027. Either way, decide deliberately now rather than drifting into the deadline.

    Horizon ESG helps reporting teams navigate ESG complexity with clarity - including scoping and collecting against the right datapoint set the first time. If you are weighing your ESRS 2.0 options, see how our CSRD reporting software keeps your data audit-ready whichever basis you report on.

  • CSRD Assurance: What Limited Assurance Means and How to Prepare

    CSRD assurance is the independent verification of a company’s sustainability report by a qualified third party. Under the directive, all in-scope companies must obtain at least limited assurance on their ESRS disclosures, and the Omnibus Directive of 18 March 2026 removed the Commission’s power to ever mandate reasonable assurance. This requirement applies from your first CSRD reporting year.

    What is CSRD assurance?

    Assurance is not an audit in the traditional financial sense, but it serves a similar purpose: giving stakeholders confidence that the reported information is materially accurate and prepared in accordance with the applicable standards.

    CSRD introduces two levels of assurance. Limited assurance is required initially — this involves the assurance provider reviewing your data, processes, and disclosures to conclude whether anything has come to their attention that causes them to believe the report is materially misstated. It is less intensive than reasonable assurance but still demands structured evidence and documentation.

    Reasonable assurance — the standard applied to financial statements — is no longer on the EU roadmap. The Omnibus removed the Commission’s empowerment to mandate it, and the delegated act adopting limited assurance standards is due by 1 July 2027. This requires the assurance provider to obtain sufficient evidence to positively confirm that disclosures are free from material misstatement. The gap between limited and reasonable assurance is significant in terms of evidence requirements, so organisations building their reporting processes now should still design for it, because a customer, lender or investor can commission reasonable assurance voluntarily under ISSA 5000.

    What do assurance providers actually check?

    Understanding what assurance providers examine helps you build processes that pass scrutiny the first time. Their focus areas typically include:

    Data accuracy and traceability

    Every figure in your sustainability report must be traceable back to its source. The assurance provider will select a sample of disclosed data points and follow the trail from the published number through your calculation methodology to the underlying activity data. If that trail is broken — because data was manually transferred between systems, or because the calculation methodology is undocumented — the finding will be flagged.

    Methodology consistency

    Have you applied the same calculation methodologies consistently across reporting entities, time periods, and data categories? Changes in methodology between years must be disclosed and justified. The assurance provider will check that emission factors, conversion rates, and estimation approaches are applied uniformly and are appropriate for your sector and geography.

    Double materiality process documentation

    Your double materiality assessment determines which ESRS standards you report against. The assurance provider will examine how you identified material topics, what scoring methodology you used, how stakeholder input was incorporated, and whether exclusion decisions are justified. A materiality assessment without documented methodology and evidence will not survive assurance review.

    Governance and internal controls

    Who approved the data? Who reviewed the calculations? What internal controls prevent errors from propagating through the report? The assurance provider expects to see defined roles, approval workflows, and segregation of duties between data entry and data review. This is where governance alignment becomes critical.

    Completeness of ESRS disclosures

    Based on your materiality assessment, certain ESRS standards apply to your organisation. The assurance provider will verify that all required disclosure points under those standards are addressed — either with reported data or with a documented explanation of why a specific disclosure is not applicable. Missing disclosures without explanation will be flagged as findings.

    How to prepare your organisation for assurance

    Build audit trails from day one. Every data entry should be timestamped, attributed to a named user, and linked to source documentation. If you are using audit-ready ESG reporting software, this should be automatic. If you are using spreadsheets, you need a manual logging process — which is why most organisations undergoing CSRD assurance move to dedicated software before their first engagement.

    Document your methodology decisions. For every calculation approach, emission factor selection, and estimation technique, maintain a methodology note explaining what you chose, why you chose it, and what alternatives you considered. This documentation should be prepared as you build your reporting process, not retrospectively assembled before the assurance engagement.

    Maintain evidence for materiality conclusions. Your double materiality assessment should be supported by stakeholder engagement records, scoring matrices, threshold justifications, and minutes from governance meetings where material topics were approved. The assurance provider will ask for this documentation.

    Establish clear data ownership. Every data point in your CSRD report should have a named owner — the person responsible for its accuracy. When the assurance provider queries a figure, you need to know immediately who can provide the explanation and evidence.

    Run an internal dry run. Before engaging your external assurance provider, conduct an internal review that simulates the assurance process. Select a sample of data points, trace them back to source, check methodology consistency, and verify completeness against ESRS requirements. This identifies gaps you can fix before they become formal findings.

    Common assurance pitfalls

    Engaging the assurance provider too late. If your first conversation with the assurance provider is after your report is drafted, you have missed the window for them to review your methodology and data processes. Engage them during the preparation phase — most providers offer pre-assurance advisory services for first-time reporters.

    Assuming limited assurance is easy. Limited assurance is less intensive than reasonable assurance, but it is not a rubber stamp. Providers will still examine your data, test your calculations, and review your governance processes. Organisations that treat limited assurance casually often receive qualified opinions or management letter findings.

    Inconsistent methodology across entities. Multi-site or multi-entity organisations frequently apply different calculation approaches across locations, then struggle to reconcile them at group level. Standardise your methodology before data collection begins.

    Undocumented Scope 3 estimates. Most organisations use estimates for Scope 3 emissions, which is acceptable under both the GHG Protocol and ESRS E1. However, the estimation methodology, data sources, and assumptions must be clearly documented. An undocumented estimate is an unsupported figure.

    No separation between data entry and review. If the same person enters and approves data, you have a governance weakness. Assurance providers expect a review step between data entry and final disclosure, even in small teams.

    The timeline — when to engage your assurance provider

    For a company reporting on FY2025 with a filing date in 2026, a realistic assurance timeline looks like this:

    6-9 months before filing: Initial conversation with the assurance provider. Discuss scope, timeline, fee structure, and their expectations for documentation and access.

    4-6 months before filing: Pre-assurance advisory engagement. The provider reviews your methodology documents, data collection processes, and materiality assessment. You receive early feedback and can address gaps.

    2-3 months before filing: Data collection close. Final figures are calculated and internal review is completed.

    1-2 months before filing: Formal assurance engagement. The provider conducts their review, tests data samples, and issues their assurance opinion.

    How Horizon ESG supports assurance readiness

    Horizon ESG is designed with assurance in mind. Every data entry is automatically timestamped and attributed. Calculation methodologies are documented within the platform. Approval workflows enforce separation between data entry and review. And your assurance provider can be granted read-only access to trace any disclosed figure back to its source data without requiring your team to compile evidence packs manually.

    The result is a reporting process that is assurance-ready by design, not by afterthought. Learn more about how Horizon ESG can support your assurance readiness.

  • CSRD Readiness Checklist: 12 Steps Before Your First Report

    To prepare for CSRD, organisations should follow a structured readiness process: confirm whether they fall in scope, identify their reporting deadline, conduct a double materiality assessment, map their value chain, establish data collection workflows, and secure assurance early. This 12-step CSRD readiness checklist walks you through each stage so you can approach your first report with confidence rather than last-minute scrambling.

    What Is CSRD Readiness?

    CSRD readiness refers to the state of organisational preparedness required to produce a compliant sustainability report under the EU’s Corporate Sustainability Reporting Directive. Unlike previous non-financial reporting requirements, the CSRD demands structured, auditable disclosures aligned with the European Sustainability Reporting Standards (ESRS). That means readiness is not simply about writing a report — it is about building the internal systems, governance structures, and data pipelines that make accurate, verifiable reporting possible.

    A CSRD readiness assessment evaluates where your organisation currently stands against these requirements and identifies the gaps you need to close before your first filing deadline. The earlier you begin this process, the less disruptive it becomes. Companies that treat CSRD preparation as a phased project — rather than a year-end compliance exercise — consistently report smoother outcomes and fewer audit issues.

    The 12-Step CSRD Readiness Checklist

    1. Determine If You Are in Scope

    The CSRD is rolling out in waves. Large public-interest entities (over 500 employees) began reporting in 2025 on FY2024 data. The second wave, covering large companies meeting two of three thresholds — over 250 employees, EUR 50 million turnover, or EUR 25 million in assets — reports in 2026 on FY2025 data. Listed SMEs follow in 2027, with a possible opt-out until 2028. Non-EU companies generating over EUR 150 million in the EU enter scope from 2029. Check the thresholds carefully. Many mid-sized businesses are surprised to find they qualify earlier than expected, particularly subsidiaries of larger groups.

    2. Identify Your Reporting Year and First Filing Deadline

    Once you have confirmed you are in scope, pin down the exact financial year you need to report on and the corresponding filing date. Your CSRD report will be included within your management report, which means the deadline aligns with your annual financial reporting cycle. If you are in the second wave, your first report covers FY2025 data and must be filed in 2026. This distinction matters because data collection needs to begin at the start of the reporting year — not when the report is due. Work backwards from the filing date to build a realistic preparation timeline.

    3. Conduct a Gap Analysis Against ESRS Requirements

    The European Sustainability Reporting Standards comprise 12 standards spanning environmental, social, and governance topics. Each standard contains specific disclosure requirements and data points. A gap analysis maps your current ESG reporting practices against these requirements to identify what you already collect, what you partially cover, and what is entirely missing. Focus on the mandatory cross-cutting standards (ESRS 1 and ESRS 2) first, then move to the topical standards that your double materiality assessment identifies as relevant. This exercise gives you a clear remediation roadmap and helps you prioritise resource allocation.

    4. Complete Your Double Materiality Assessment

    Double materiality is the foundation of your CSRD report. It requires you to assess sustainability topics from two perspectives: financial materiality (how sustainability issues affect your business) and impact materiality (how your business affects people and the environment). This assessment determines which ESRS topical standards you must report on and which you can legitimately exclude. It also shapes your stakeholder engagement strategy. For a detailed walkthrough of the methodology, see our complete guide to double materiality under CSRD. Do not underestimate the time this step requires — most organisations need 8 to 12 weeks to complete it properly.

    5. Map Your Value Chain for Scope 3 Reporting

    ESRS E1 (Climate Change) requires disclosure of Scope 1, 2, and 3 greenhouse gas emissions. Scope 3 — covering indirect emissions across your upstream and downstream value chain — is typically the largest category and the hardest to measure. Begin by mapping your key suppliers, distributors, and end-of-life product impacts. Identify which Scope 3 categories are most material to your business. You will likely need to rely on spend-based estimates initially before transitioning to activity-based data over time. Engaging key suppliers early and establishing data-sharing agreements will improve data quality in subsequent reporting cycles.

    6. Establish Data Collection Processes Across Departments

    CSRD reporting pulls data from across the entire organisation — HR for workforce metrics, procurement for supply chain data, facilities for energy consumption, finance for climate-related financial risks. Identify every data owner and establish clear collection processes, frequencies, and quality standards. Spreadsheets may work for a first cycle, but they introduce error risk and make audit trails difficult. Investing in purpose-built ESG reporting software early reduces manual effort and improves consistency. Define data definitions clearly so that every department reports metrics in the same way.

    7. Assign Internal Ownership and Governance Structure

    CSRD compliance cannot sit with a single sustainability officer. It requires a governance structure with clear accountability at the board level, an executive sponsor, and designated owners for each ESRS topic. Consider establishing a cross-functional CSRD steering committee that includes representatives from finance, legal, operations, HR, and sustainability. Define who signs off on the final report, who is responsible for data quality, and how disputes over materiality or disclosure are resolved. Our guide on CSRD governance alignment provides a practical framework for structuring this effectively.

    8. Select Your Reporting Software Platform

    The complexity and volume of ESRS data points make manual reporting impractical at scale. Evaluate ESG reporting software platforms based on their ESRS alignment, data integration capabilities, audit trail functionality, and XBRL tagging support — since CSRD reports must be digitally tagged in European Single Electronic Format (ESEF). Consider whether the platform supports double materiality workflows, automated data validation, and multi-entity consolidation if you operate across subsidiaries. Select your platform early enough to allow for implementation, data migration, and user training before the reporting year begins.

    9. Build Your Audit Trail from Day One

    CSRD reports are subject to mandatory assurance — initially limited assurance, moving to reasonable assurance over time. Your assurance provider will need to trace every disclosed figure back to its source. This means maintaining documentation of data origins, calculation methodologies, assumptions, estimation techniques, and any manual adjustments. Build this audit trail from the very start of your data collection process, not retrospectively when the auditor arrives. Version control for documents, approval workflows for data submissions, and timestamped records of changes all contribute to a robust audit trail that will make assurance smoother and less costly.

    10. Engage Your Assurance Provider Early

    Do not wait until your report is drafted to approach an assurance provider. Engage them during the preparation phase so they can review your methodology, flag potential issues with data quality or materiality conclusions, and confirm that your processes meet assurance standards. Many audit firms are experiencing significant demand as thousands of companies enter CSRD scope simultaneously, so early engagement also secures capacity. If your financial auditor offers sustainability assurance, there may be efficiencies in using the same firm, but evaluate independence and expertise carefully. A pre-assurance readiness review can save considerable time and cost later.

    11. Train Your Team on ESRS Disclosure Requirements

    CSRD reporting is not just a sustainability team exercise. Finance teams need to understand climate-related financial disclosures. HR must know what workforce data is required and how to report it consistently. Board members need sufficient literacy to oversee and approve the report. Invest in targeted training that is role-specific rather than generic. Focus on the practical mechanics: what data each team needs to provide, in what format, by what deadline, and to what quality standard. Regular briefings throughout the reporting cycle keep teams aligned and reduce the risk of last-minute data gaps or inconsistencies.

    12. Create a Reporting Timeline with Internal Milestones

    Your CSRD preparation needs a detailed project plan with clear milestones, not just a filing deadline. Work backwards from your submission date and build in time for data collection close, internal review cycles, management sign-off, assurance fieldwork, and XBRL tagging. Allow buffer time — first-year reporting always takes longer than expected. Key milestones should include: completion of the double materiality assessment, data collection cut-off dates for each quarter, first draft review, assurance readiness review, board approval, and final submission. Assign owners to each milestone and track progress through regular steering committee meetings.

    Common CSRD Readiness Mistakes

    Even well-resourced organisations stumble during CSRD preparation. These are the mistakes we see most frequently:

    1. Starting too late. Companies that begin their readiness assessment less than 12 months before their filing deadline consistently struggle with data gaps and rushed disclosures. CSRD preparation is a multi-year journey, not a quarter-end sprint.
    2. Treating it as a sustainability-only project. Without buy-in and active participation from finance, legal, HR, and operations, data collection stalls and governance gaps appear during assurance.
    3. Underestimating double materiality. A superficial materiality assessment leads to either over-reporting (wasting resources on immaterial topics) or under-reporting (creating compliance risk). Invest the time to do it properly.
    4. Ignoring the audit trail. Collecting data without documenting sources, methodologies, and assumptions creates enormous problems when assurance providers request evidence. Retrofitting audit trails is far more expensive than building them from the start.
    5. Choosing software too late. Implementing a reporting platform mid-cycle forces dual processes and increases error risk. Select and configure your platform before the reporting year begins.
    6. Neglecting value chain data. Scope 3 and supply chain disclosures require supplier engagement that takes months to establish. Start building those relationships and data-sharing agreements early.

  • CSRD Timeline 2025-2028: Who Reports When and What You Need to Know

    CSRD reporting began in financial year 2024, with the first sustainability reports due in 2025 from large public-interest entities. The directive then rolls out in four waves through to 2029, progressively bringing large companies, listed SMEs, and non-EU businesses into scope. This guide sets out the exact deadlines, who falls into each wave, and what the EU Omnibus proposal means for your timeline.

    Update, 23 September 2026: The Omnibus I Directive came into force on 18 March 2026 and overtook much of this timeline. CSRD now applies only to companies with more than 1,000 employees and more than EUR 450m net turnover, both tests together, which cuts scope from roughly 50,000 companies to roughly 5,000. The wave thresholds and the Omnibus discussion below describe the rules as they stood before that date. If you now sit outside scope, the pressure you are more likely to feel is customer data requests, and there is a legal ceiling on those: see our guide to the CSRD value chain cap.

    CSRD Implementation Timeline at a Glance

    The table below summarises all four CSRD reporting waves. If you are unsure which wave applies to your organisation, see the decision tree further down this page.

    Wave Who Is in Scope Financial Years Covered First Report Due Key Details
    Wave 1 Large public-interest entities already subject to the NFRD (>500 employees) FY 2024 2025 Approx. 11,700 companies across the EU. Reports must follow the full European Sustainability Reporting Standards (ESRS).
    Wave 2 Other large undertakings meeting at least 2 of 3 criteria: >250 employees, >€50m turnover, >€25m balance sheet total FY 2025 2026 The largest new cohort – an estimated 35,000+ companies. Includes private companies meeting the size thresholds. First time many mid-market businesses face mandatory sustainability reporting.
    Wave 3 Listed SMEs, small and non-complex credit institutions, and captive insurance undertakings FY 2026 2027 Listed SMEs may opt out until FY 2028 (reporting in 2029). Simplified ESRS standards (LSME ESRS) will apply. Subject to potential delay under the Omnibus proposal – see below.
    Wave 4 Non-EU (third-country) companies with >€150m net turnover in the EU and at least one EU subsidiary or branch FY 2028 2029 Reports prepared by the EU subsidiary or branch on behalf of the third-country parent. A dedicated third-country ESRS is expected.

    For a deeper look at how Wave 2 affects mid-sized businesses specifically, read our CSRD guide for medium-sized businesses.

    What Changed in 2025-2026?

    In February 2025 the European Commission published the Omnibus Simplification Package, a sweeping proposal to reduce regulatory burden across several EU sustainability directives, including the CSRD. The key proposed changes are as follows:

    • Wave 2 two-year delay: The Commission proposed postponing the first reporting deadline for Wave 2 companies by two years – from FY 2025 (report in 2026) to FY 2027 (report in 2028). As of early 2026, this delay has not been formally adopted into law, but the European Parliament and Council are actively negotiating it.
    • Wave 3 may be removed entirely: Under certain versions of the Omnibus text, listed SMEs could be taken out of mandatory CSRD scope altogether. This remains under discussion.
    • Scope thresholds raised: The proposal would increase the size thresholds for “large undertaking” status, potentially excluding a significant number of companies currently assumed to be in Wave 2.
    • Simplified value chain reporting: Companies may no longer be required to collect detailed sustainability data from SME suppliers, which would ease the indirect burden on smaller businesses in the supply chain.
    • Voluntary reporting encouraged: Companies falling below the revised thresholds would still be able to report voluntarily using simplified standards.

    What this means in practice: If your company sits in Wave 2 or Wave 3, you should continue preparing as though the original deadlines stand. Legislative delays are possible but not guaranteed, and companies that wait risk falling behind if the Omnibus amendments are diluted or rejected. Investors and customers will still expect sustainability data regardless of regulatory shifts. If you are evaluating tooling to meet these deadlines, see our comparison of the best ESG reporting software for 2026.

    For guidance on how governance structures should evolve alongside reporting obligations, see our article on CSRD governance alignment and reporting.

    UK Companies – Does CSRD Apply to You?

    Post-Brexit, the CSRD is not directly transposed into UK law. However, UK businesses can still fall within its reach in three ways:

    1. Direct scope through EU presence

    If your UK-headquartered group has a subsidiary incorporated in an EU member state that meets the relevant size thresholds, that subsidiary must report under the CSRD according to its wave. Alternatively, if you are listed on an EU-regulated market, you are directly in scope.

    2. Wave 4 – third-country reporting

    UK companies generating more than €150 million in net turnover within the EU will fall into Wave 4 (FY 2028, reporting in 2029), provided they have at least one EU branch or subsidiary above the applicable thresholds.

    3. Indirect scope – value chain data requests

    Even if your company is not directly captured, EU customers reporting under the CSRD will need sustainability data from their value chain. If you supply goods or services to companies in Waves 1 or 2, expect to receive data requests covering environmental metrics, human rights due diligence, and governance practices. Being unable to respond may put commercial relationships at risk.

    UK Sustainability Disclosure Standards (UK SDS)

    The UK Government has confirmed it will introduce its own sustainability reporting regime based on the ISSB standards (IFRS S1 and S2). The current expectation is that mandatory UK SDS reporting will begin from 2027 for the largest UK-listed companies and financial institutions, with potential phased extension to large private companies thereafter. While UK SDS differs from the ESRS in structure, there is significant overlap in the underlying data requirements. Companies preparing for CSRD will find much of that work transferable to UK SDS compliance.

    UK-based teams preparing for both regimes can see how we support them on our ESG reporting software for UK companies page.

    How to Determine Your CSRD Reporting Wave

    Use the following decision tree to identify which wave – if any – applies to your organisation:

    1. Are you an EU public-interest entity with more than 500 employees, already subject to the Non-Financial Reporting Directive (NFRD)?
      Yes → Wave 1. You should already be reporting on FY 2024.
      No → Continue.
    2. Are you an EU-incorporated company (or EU subsidiary of a non-EU group) meeting at least two of the following: >250 employees, >€50m turnover, >€25m balance sheet total?
      Yes → Wave 2. Your first reporting year is FY 2025, with the report due in 2026 (subject to potential Omnibus delay).
      No → Continue.
    3. Are you a listed SME on an EU-regulated market, a small and non-complex credit institution, or a captive insurance undertaking?
      Yes → Wave 3. First reporting year is FY 2026 (report in 2027), with an opt-out available until FY 2028. Subject to Omnibus changes.
      No → Continue.
    4. Are you a non-EU company with more than €150m net turnover generated in the EU, with at least one EU subsidiary or branch?
      Yes → Wave 4. First reporting year is FY 2028, with the report due in 2029.
      No → Continue.
    5. None of the above apply.
      You are not currently in direct scope of the CSRD. However, you may face indirect obligations through value chain data requests from EU customers or through forthcoming UK SDS requirements. Voluntary reporting using the ESRS is an option worth considering.

    If you are uncertain about your classification, particularly around consolidated vs. individual reporting, consult the full CSRD overview on our dedicated page.

    What to Do Now Based on Your Wave

    Wave 1 – Already Reporting (FY 2024)

    Your first CSRD-aligned report should already be published or in final review. Focus now on:

    • Reviewing assurance findings from your limited assurance engagement and addressing any gaps.
    • Strengthening data collection processes for your second reporting cycle, especially around Scope 3 emissions and value chain metrics.
    • Starting to embed ESRS datapoints into internal management reporting, not just annual disclosure.

    Wave 2 – Preparing Now (FY 2025, Report in 2026)

    This is the critical preparation window. You should have already completed or be actively working on:

    • Double materiality assessment: This is the foundation of your entire CSRD report. If you have not completed this, it should be your immediate priority.
    • Gap analysis against the ESRS: Map your current sustainability data collection against the required disclosure requirements and datapoints.
    • Selecting reporting software: Manual spreadsheet-based approaches will not scale. Evaluate CSRD reporting software that can handle ESRS taxonomy tagging, data aggregation, and audit trails.
    • Governance alignment: Ensure your board and management body have defined roles and responsibilities for sustainability oversight, as required by ESRS 2.
    • Engaging your value chain: Begin requesting environmental and social data from key suppliers and customers now – do not wait until the reporting deadline is upon you.

    Wave 3 – Listed SMEs (FY 2026, Report in 2027)

    Although the Omnibus proposal may delay or remove your obligations, waiting carries risk. Practical steps for now:

    • Monitor the legislative progress of the Omnibus Simplification Package closely.
    • Conduct a preliminary materiality assessment, even if simplified.
    • Begin collecting baseline environmental data (energy consumption, emissions, waste) so you are not starting from scratch if and when reporting becomes mandatory.
    • Consider voluntary reporting as a competitive differentiator with investors.

    Wave 4 – Non-EU Companies (FY 2028, Report in 2029)

    You have more lead time, but the preparation effort is substantial:

    • Confirm whether your EU revenue exceeds the €150m threshold and identify which EU subsidiaries or branches will carry the reporting obligation.
    • Start aligning group-level sustainability data collection with ESRS requirements, even if your home jurisdiction uses a different framework.
    • Use the intervening years to run a pilot CSRD report – the complexity of consolidating cross-border data should not be underestimated.

    Whichever wave you fall into, choosing the right ESG reporting software early will significantly reduce the workload and risk of non-compliance.

  • ESRS Reporting: Complete Guide for 2026

    ESRS Reporting: Complete Guide for 2026

    What Are the European Sustainability Reporting Standards?

    The European Sustainability Reporting Standards, known as ESRS, are the mandatory disclosure standards that underpin the Corporate Sustainability Reporting Directive. Developed by EFRAG and adopted by the European Commission, these standards define exactly what information companies must disclose about their environmental, social, and governance performance. Understanding ESRS is essential for any organisation that falls within CSRD scope - and increasingly relevant for companies in global supply chains that need to provide data to their European partners.

    ESRS Structure: The Complete Framework

    The ESRS framework consists of twelve standards organised into three groups, plus two cross-cutting standards that apply to every reporting organisation.

    Cross-Cutting Standards

    ESRS 1 - General Requirements. Defines the architecture of the standards, including the concepts of double materiality, due diligence, and the reporting boundary. Every organisation subject to CSRD must understand and apply ESRS 1.

    ESRS 2 - General Disclosures. Requires all in-scope companies to disclose information about governance, strategy, impact and risk management, and metrics and targets. ESRS 2 disclosures are mandatory for every reporting entity regardless of materiality assessment results.

    Environmental Standards (E1 through E5)

    • E1 - Climate Change. Covers greenhouse gas emissions (Scope 1, 2, and 3), transition plans, climate-related risks and opportunities, and energy consumption. For most organisations, this is the most data-intensive standard.
    • E2 - Pollution. Addresses air, water, and soil pollution, including substances of concern and microplastics.
    • E3 - Water and Marine Resources. Covers water consumption, withdrawal, discharge, and impacts on marine ecosystems.
    • E4 - Biodiversity and Ecosystems. Addresses impacts on biodiversity, land use change, and ecosystem services.
    • E5 - Resource Use and Circular Economy. Covers material flows, waste management, and circular economy practices.

    Social Standards (S1 through S4)

    • S1 - Own Workforce. Covers employment practices, working conditions, diversity, health and safety, and labour rights for direct employees. See our guide to ESRS S1 own workforce reporting.
    • S2 - Workers in the Value Chain. Extends workforce disclosures to workers in the supply chain and downstream value chain.
    • S3 - Affected Communities. Addresses impacts on communities where the company operates or sources materials.
    • S4 - Consumers and End-Users. Covers product safety, data privacy, and responsible marketing practices.

    Governance Standard

    • G1 - Business Conduct. Covers corporate culture, anti-corruption, whistleblowing, political engagement, and payment practices.

    How Double Materiality Determines Your Scope

    Not every topical standard applies to every organisation. The ESRS framework uses double materiality to determine which standards and data points are material to your business. You must assess both impact materiality - your organisation’s actual or potential impacts on people and the environment - and financial materiality - how sustainability matters create risks or opportunities that affect your financial position.

    Standards and data points deemed non-material through a rigorous, documented assessment can be excluded from your report. However, ESRS 2 general disclosures and E1 climate change disclosures carry a rebuttable presumption of materiality, meaning you must provide a detailed explanation if you exclude them.

    Phased Adoption Timeline

    Update, 23 September 2026: The waves below predate the Omnibus I Directive, in force since 18 March 2026. CSRD now applies only to companies with more than 1,000 employees and more than EUR 450m net turnover, both tests together, and the revised ESRS cut mandatory datapoints by more than 60%. Companies below those thresholds are most likely to meet ESRS through customer data requests.

    The original CSRD and ESRS timeline set out the following waves:

    • 2025 reporting (FY 2024): Large public-interest entities already subject to the Non-Financial Reporting Directive.
    • 2026 reporting (FY 2025): Other large undertakings meeting two of three criteria - more than 250 employees, more than EUR 50 million turnover, or more than EUR 25 million total assets.
    • 2027 reporting (FY 2026): Listed SMEs, with an option to opt out for up to two additional years.
    • 2029 reporting (FY 2028): Non-EU companies with significant EU operations meeting specified thresholds.

    What Data Do You Need?

    The data requirements for ESRS reporting are extensive. At a minimum, organisations need to prepare the following:

    • Greenhouse gas emissions data across all three scopes with supporting activity data and emission factors.
    • Energy consumption broken down by renewable and non-renewable sources.
    • Workforce metrics including headcount, diversity breakdowns, training hours, and health and safety statistics.
    • Governance data covering board composition, sustainability oversight structures, and business conduct policies.
    • Policies, targets, and action plans for each material topic.
    • Financial effects of sustainability risks and opportunities.

    How Software Helps with ESRS Compliance

    Managing over one thousand data points across twelve standards in spreadsheets is a recipe for errors, missed deadlines, and audit failures. Dedicated ESRS compliance software addresses these challenges by providing structured data collection workflows mapped to each ESRS standard, automated emission calculations with up-to-date factor databases, materiality assessment tools that determine your reporting scope, progress dashboards that show completion status across all standards, assurance-ready audit trails for every data point, and report generation in the required European Single Electronic Format.

    The right ESG reporting software does not just make compliance possible - it makes it efficient, reducing the cost and effort of annual reporting while improving data quality and stakeholder confidence.

    Preparing Your Organisation

    Start with these practical steps:

    1. Determine your reporting timeline. Identify which wave of CSRD applies to your organisation and work backwards to set internal milestones.
    2. Conduct a gap analysis. Compare your current data collection and reporting processes against ESRS requirements to identify what you already have and what you need.
    3. Complete your double materiality assessment. This determines the scope of your report and should involve internal and external stakeholders.
    4. Select your technology platform. Choose software that covers all applicable ESRS standards and integrates with your data sources.
    5. Build your data collection network. Identify data owners across the organisation and establish collection workflows and timelines.
    6. Engage your auditor early. Discuss your reporting approach and data management processes with your assurance provider before the reporting deadline.

  • Automated ESG Reporting: How AI Cuts Effort 70%

    Automated ESG Reporting: How AI Cuts Effort 70%

    The Manual Reporting Problem

    ESG reporting has traditionally been a manual, resource-intensive process. Sustainability teams spend weeks collecting data from dozens of sources, matching activities to emission factors, chasing missing information, reconciling inconsistencies, and drafting narrative disclosures. For organisations reporting under CSRD, GRI, CDP, and other frameworks simultaneously, the workload multiplies with every standard.

    Artificial intelligence is changing this equation fundamentally. Organisations that deploy AI-powered ESG automation are reducing manual reporting effort by up to seventy percent - not by cutting corners, but by automating the repetitive tasks that consume the most time while maintaining the accuracy and rigour that regulators and auditors demand.

    What AI Actually Does in ESG Reporting

    Automated Data Collection

    AI-powered platforms connect to your existing business systems - ERP, HR, energy management, procurement, travel booking - and extract ESG-relevant data automatically. Instead of sending spreadsheet templates to facility managers and waiting weeks for responses, the system pulls utility consumption, headcount data, travel records, and procurement spend on a scheduled basis. Learn more about how AI automation works in practice.

    Intelligent Emission Factor Matching

    One of the most time-consuming tasks in carbon reporting is matching activity data to the correct emission factors. AI analyses your activity descriptions, units, geographies, and source categories to suggest the most appropriate emission factors from databases like DEFRA, EPA, ecoinvent, and IPCC. The system learns from your corrections, improving accuracy over time. This capability alone can save dozens of hours per reporting cycle, particularly for complex carbon accounting across Scope 1, 2, and 3.

    Gap Detection and Anomaly Flagging

    AI continuously monitors your data for completeness and consistency. It identifies missing data points before they become audit findings, flags statistical anomalies that may indicate errors - such as a facility reporting ten times its typical energy consumption - and highlights year-over-year changes that require explanation. This proactive approach means your team catches problems early rather than discovering them during assurance review.

    Narrative Drafting

    CSRD and other frameworks require extensive narrative disclosures alongside quantitative data. AI assists by generating first drafts of narrative sections based on your data, policies, and previous reports. These drafts are starting points, not final outputs - your sustainability experts review, refine, and approve every disclosure. But starting from a structured draft rather than a blank page saves significant time and ensures consistent quality.

    Predictive Analytics

    Beyond reporting, AI helps organisations forecast emissions trajectories, model the impact of reduction initiatives, and identify the highest-impact areas for improvement. This transforms ESG reporting from a backward-looking compliance exercise into a forward-looking strategic tool.

    The ROI of ESG Automation

    The return on investment from AI-powered ESG automation comes from several sources:

    • Time savings. Teams that previously spent twelve to sixteen weeks on an annual report cycle can complete the same work in four to six weeks, freeing capacity for strategic sustainability work.
    • Error reduction. Automated validation and emission factor matching eliminate the most common sources of data errors, reducing restatement risk and audit findings.
    • Faster audit cycles. Complete audit trails and automated documentation reduce the time and cost of external assurance by up to forty percent.
    • Staff efficiency. Rather than hiring additional reporting analysts, organisations can handle growing reporting requirements with their existing team.
    • Better decisions. Real-time dashboards and predictive analytics enable faster, more informed sustainability decisions.

    The Human-in-the-Loop Approach

    Effective AI in ESG reporting is not about replacing human judgement. It is about augmenting it. The best platforms follow a human-in-the-loop model where AI handles data processing, pattern recognition, and draft generation, while human experts retain control over materiality decisions, narrative tone, strategic priorities, and final approval of every disclosure.

    This approach delivers the speed and efficiency of automation without sacrificing the contextual understanding and professional judgement that sustainability reporting demands. Your team remains accountable - the AI simply removes the drudge work that prevents them from focusing on what matters.

    Security and Privacy Considerations

    ESG data often includes sensitive information - employee demographics, supply-chain relationships, energy contracts, and financial data. When evaluating AI-powered platforms, ensure the vendor addresses these critical questions:

    • Where is data processed and stored? Look for platforms with data residency options aligned to your jurisdiction.
    • Is your data used to train AI models? Reputable vendors isolate customer data and do not use it for model training.
    • What encryption standards are in place for data at rest and in transit?
    • Does the platform comply with GDPR and other applicable data protection regulations?
    • What access controls and authentication mechanisms are available?

    Getting Started with AI-Powered ESG Reporting

    You do not need to automate everything at once. Start with the areas that consume the most manual effort - typically data collection and emission factor matching - and expand automation as your team gains confidence. The best platforms are designed for incremental adoption, allowing you to enable AI capabilities progressively.

  • ESG Data Management: Beyond Spreadsheets

    ESG Data Management: Beyond Spreadsheets

    The Spreadsheet Problem in ESG Reporting

    Most organisations start their ESG journey in spreadsheets. It makes sense at first - spreadsheets are familiar, flexible, and free. But as reporting requirements grow, data volumes increase, and stakeholder expectations rise, spreadsheets become the weakest link in your sustainability programme. They do not scale, they are error-prone, and they create compliance risks that no sustainability leader should accept.

    If your team spends more time wrangling data than analysing it, this guide is for you.

    Five Problems Spreadsheets Create for ESG Teams

    1. Version Control Chaos

    When multiple team members edit copies of the same spreadsheet, version control collapses. Which file is the latest? Did someone overwrite the corrected emissions factors? Was the Q3 data already validated? These questions consume hours of productive time and introduce real risk of reporting inaccurate data to regulators and investors.

    2. Manual Errors Compound

    Research consistently shows that nearly ninety percent of complex spreadsheets contain errors. In ESG reporting, a single misplaced decimal in an emission factor, a broken formula, or a copy-paste mistake can cascade through your entire carbon footprint calculation. These errors are difficult to detect and expensive to correct - especially after a report has been published or submitted for assurance.

    3. No Audit Trail

    Spreadsheets do not maintain a meaningful audit trail. When an auditor asks who entered a specific data point, when it was modified, and what the original source was, a spreadsheet cannot answer. With CSRD requiring limited assurance and reasonable assurance on the horizon, this gap alone can disqualify your reporting process.

    4. Scalability Limits

    Tracking ten facilities in a spreadsheet is manageable. Tracking fifty facilities across three continents with Scope 1, 2, and 3 emissions, social metrics, governance data, and multiple reporting frameworks is not. Spreadsheets hit performance limits, become unwieldy to navigate, and make cross-referencing data across sheets or workbooks painfully slow.

    5. Collaboration Bottlenecks

    ESG data comes from across the organisation - facilities, HR, procurement, finance, operations. Spreadsheet-based processes typically rely on email chains to request data, leading to delays, missing responses, and no visibility into collection progress. Sustainability teams spend weeks chasing data contributors every reporting cycle.

    Signs You Have Outgrown Spreadsheets

    • Your reporting cycle takes more than eight weeks from data collection to final report.
    • You have experienced at least one data error that required a correction or restatement.
    • Your team spends more than fifty percent of their time on data management rather than analysis and strategy.
    • You are reporting under multiple frameworks and duplicating data entry for each one.
    • An auditor has raised concerns about data traceability or documentation.
    • You are expanding into Scope 3 reporting and cannot manage the complexity in flat files.

    What a Dedicated ESG Platform Gives You

    Switching to a purpose-built ESG reporting platform transforms how your team works. Here is what changes:

    Centralised data management. All ESG data lives in one system of record with role-based access, eliminating version conflicts and ensuring everyone works from the same source of truth.

    Automated data collection. Integrations with ERP, HR, and energy management systems pull data automatically, reducing manual entry and the errors that come with it.

    Built-in validation. Automated checks flag outliers, missing data, and inconsistencies before they reach your final report. Validation rules catch the errors that human reviewers miss.

    Complete audit trail. Every data point is traceable - who entered it, when, from what source, and every change made along the way. This is essential for assurance readiness.

    AI-powered efficiency. Modern platforms use artificial intelligence to automate emission factor matching, gap detection, and even narrative drafting, cutting manual effort dramatically.

    Multi-framework reporting. Enter data once, report across CSRD, GRI, CDP, ISSB, and other frameworks. The platform maps your data to the requirements of each standard automatically.

    How to Migrate from Spreadsheets

    Migration does not have to be disruptive. Follow these steps for a smooth transition:

    1. Audit your current data. Document every spreadsheet, data source, and process your team uses today. Identify what data is clean and what needs remediation.
    2. Define your requirements. List the frameworks you report under, the data points you collect, and the integrations you need.
    3. Select your platform. Evaluate vendors against your requirements. Run a pilot with real data.
    4. Import historical data. Most platforms support bulk import from CSV or Excel files. Prioritise the most recent two to three years of data for trend analysis.
    5. Configure workflows. Set up data collection workflows, approval chains, and automated reminders for data contributors.
    6. Train your team. Invest in proper onboarding - not just for the sustainability team but for every data contributor across the organisation.
    7. Run in parallel. For one reporting cycle, run both your old spreadsheet process and the new platform in parallel to validate outputs and build confidence.

    The Cost of Waiting

    Every reporting cycle spent in spreadsheets is a cycle of unnecessary risk and wasted effort. The organisations that invest in proper ESG data management infrastructure now are building a competitive advantage - faster reporting, more accurate data, lower audit costs, and sustainability teams that can focus on driving real environmental and social impact rather than managing files.

  • CSRD Software Comparison: What to Look For

    CSRD Software Comparison: What to Look For

    Update, 30 September 2026: This comparison was written before the Omnibus I Directive came into force on 18 March 2026. CSRD now applies only to companies with more than 1,000 employees and more than EUR 450m net turnover, both tests together, so far fewer companies are in scope than the introduction below suggests. The selection criteria still hold. For named vendors side by side, see our comparison of eight ESG reporting platforms.

    Why CSRD Software Selection Matters Now

    The Corporate Sustainability Reporting Directive is reshaping how European and international companies disclose sustainability information. With the first wave of reporting obligations already underway and subsequent waves bringing thousands more companies into scope, choosing the right CSRD software is one of the most consequential technology decisions your organisation will make in 2026.

    This guide provides a structured framework for comparing CSRD software options based on the capabilities that genuinely matter for compliance, efficiency, and long-term value.

    Core Capabilities Every CSRD Platform Needs

    Full ESRS Coverage

    The European Sustainability Reporting Standards are the backbone of CSRD compliance. Your software must cover all twelve standards - the cross-cutting standards (ESRS 1 and ESRS 2) as well as the topical standards spanning environmental (E1 through E5), social (S1 through S4), and governance (G1). Partial coverage creates gaps that auditors will flag. Review our detailed breakdown of CSRD requirements to understand the full scope of what your software must address.

    Double Materiality Assessment Support

    CSRD requires organisations to conduct a double materiality assessment - evaluating both financial materiality (how sustainability issues affect the business) and impact materiality (how the business affects people and the environment). The best platforms provide structured workflows for stakeholder engagement, materiality mapping, and threshold setting, rather than leaving you to manage this critical process in standalone documents.

    Data Point Management

    CSRD reporting involves over one thousand individual data points. Your software should map each data point to the relevant ESRS standard, track completion status, assign ownership to data contributors across the organisation, and flag mandatory versus voluntary disclosures based on your materiality results. Without this granular management layer, teams lose track of requirements and deadlines.

    Feature Comparison Framework

    When evaluating multiple platforms, use this framework to score each option consistently:

    1. Regulatory Intelligence

    How quickly does the platform incorporate regulatory updates? ESRS standards are still evolving, with sector-specific standards and SME standards in development. Platforms that maintain a dedicated regulatory team and push updates automatically score highest in this category.

    2. Workflow and Collaboration

    CSRD reporting involves dozens of contributors across departments. Evaluate task assignment, approval workflows, role-based access controls, and notification systems. The platform should make it easy for non-sustainability staff to contribute data without extensive training.

    3. Assurance Readiness

    Limited assurance is already required, with reasonable assurance on the horizon. Your software must maintain a complete audit trail - every data entry, edit, approval, and source document should be logged with timestamps and user attribution. Some platforms offer auditor portals that give external assurance providers direct read-only access, significantly reducing audit preparation time.

    4. Integration Capabilities

    CSRD data comes from ERP systems, HR platforms, energy management tools, procurement databases, and more. Evaluate the breadth and depth of available integrations, API flexibility, and whether the vendor supports custom connectors for proprietary systems.

    5. Reporting Output

    The platform should generate XHTML-tagged reports compatible with the European Single Electronic Format. Evaluate the quality of narrative templates, data visualisations, and the ability to export reports in multiple formats for different audiences - regulators, investors, and internal stakeholders.

    What Separates Good CSRD Software from Great

    Good software checks the compliance boxes. Great software accelerates your entire sustainability programme. Look for platforms that connect CSRD reporting to operational improvement - using the data you collect not just for disclosure but for identifying reduction opportunities, benchmarking performance, and supporting strategic decisions.

    Dedicated CSRD reporting software should also handle the transition from voluntary to mandatory reporting gracefully, allowing organisations that previously reported under GRI or TCFD to map existing data to ESRS requirements without starting from scratch.

    Evaluation Process Best Practices

    • Define your scope first. Know which ESRS standards apply based on your materiality assessment before evaluating software.
    • Involve IT early. Integration requirements and security reviews take time - start these conversations during the evaluation, not after selection.
    • Request a proof of concept. Load real data into the platform and test end-to-end workflows for at least one reporting topic.
    • Check the vendor roadmap. Ask about plans for sector-specific ESRS standards, AI capabilities, and assurance features.
    • Talk to existing customers. References from organisations with similar complexity and reporting obligations are invaluable.

    Timeline Considerations

    Implementation timelines for CSRD software typically range from six to sixteen weeks depending on organisational complexity, data source integration, and internal readiness. Start your evaluation at least six months before your first reporting deadline to allow for selection, implementation, data migration, and team training.

    How to Choose ESG Reporting Software in 2026

    Why Choosing the Right ESG Software Matters

    ESG reporting is no longer optional for most organisations. Regulatory pressure from frameworks like CSRD, investor expectations, and supply-chain requirements mean that every company needs a reliable system for collecting, managing, and disclosing sustainability data. Choosing the wrong platform wastes budget, creates compliance risks, and frustrates teams. Choosing the right one accelerates your entire sustainability programme.

    This guide walks you through the key criteria for evaluating ESG reporting software so you can make a confident, informed decision in 2026.

    Essential Features to Look For

    1. Framework Coverage

    Your software should support the reporting frameworks that matter to your business - CSRD and ESRS, GRI, ISSB, TCFD, CDP, and any sector-specific standards. Look for platforms that update their framework libraries as standards evolve, rather than requiring manual template changes. A platform built around best-practice ESG reporting will handle multiple frameworks simultaneously without duplicating data entry.

    2. Data Collection and Integration

    Manual data entry is the bottleneck in most ESG programmes. Evaluate whether the platform can connect to your existing systems - ERP, HR, energy management, procurement - via API or direct integration. Automated data ingestion from utility invoices, spreadsheets, and IoT sensors saves significant time and reduces errors.

    3. Audit Trail and Assurance Readiness

    As limited and reasonable assurance requirements expand under CSRD, your software must maintain a complete audit trail. Every data point should be traceable to its source, with timestamps, user attribution, and change logs. If an auditor cannot follow the data lineage, your platform is not fit for purpose.

    4. Carbon and Emissions Calculations

    Scope 1, 2, and 3 emissions calculations are at the heart of environmental reporting. The software should include up-to-date emission factor databases, support location-based and market-based methods, and handle complex Scope 3 categories like purchased goods, business travel, and employee commuting.

    5. AI and Automation Capabilities

    Modern platforms use artificial intelligence for emission factor matching, gap detection, anomaly flagging, and even narrative drafting. These capabilities can reduce reporting effort by up to seventy percent, freeing your sustainability team to focus on strategy rather than data wrangling.

    Red Flags When Evaluating Vendors

    • No live demo available. Any credible vendor should let you test the platform with your own data before committing.
    • Pricing opacity. If a vendor cannot give you a clear breakdown of licence fees, implementation costs, and ongoing support charges, proceed with caution.
    • Lock-in tactics. Ask about data export. If you cannot extract your raw data in standard formats at any time, the platform is holding your data hostage.
    • Slow update cycles. Regulatory landscapes change rapidly. Vendors that update frameworks annually rather than quarterly will leave you exposed.
    • No customer references. Ask for case studies or references from organisations similar to yours in size and sector.

    Questions to Ask Every Vendor

    Prepare a structured evaluation scorecard and ask each vendor the same set of questions. Here are the most important ones:

    1. Which reporting frameworks do you support out of the box, and how quickly do you incorporate updates?
    2. How does your platform handle data from multiple subsidiaries, geographies, and business units?
    3. What integrations are available, and what is the typical implementation timeline?
    4. How do you ensure data security and privacy, especially for sensitive employee or supply-chain data?
    5. What does your assurance and audit support look like - can auditors access the platform directly?
    6. What training and onboarding support do you provide?
    7. What is the total cost of ownership over three years, including implementation, licences, support, and upgrades?

    How to Run a Successful Pilot

    Before signing a multi-year contract, run a focused pilot. Select one business unit or one reporting framework and test the platform for four to six weeks. Evaluate data import, user experience, report output quality, and vendor responsiveness. Involve both your sustainability team and your IT department to test integrations and security requirements.

    A good pilot reveals whether the vendor’s promises match reality. Check our pricing page to understand how Horizon ESG structures its plans so you can compare costs transparently.

    Total Cost of Ownership Considerations

    The sticker price of ESG software is only part of the equation. Factor in implementation and configuration costs, internal staff time for setup and training, ongoing subscription or licence fees, the cost of integrations or custom development, and the hidden cost of manual workarounds if the platform falls short. A platform that costs more upfront but eliminates spreadsheet-based processes and reduces audit preparation time often delivers a lower total cost of ownership over three to five years.

    Making Your Final Decision

    Shortlist two or three vendors. Score each against your requirements matrix. Weight the criteria that matter most to your organisation - framework coverage, ease of use, scalability, or integration depth. Involve key stakeholders from sustainability, finance, IT, and executive leadership in the final decision.

    The right ESG reporting software becomes the backbone of your sustainability programme, enabling accurate disclosure, efficient operations, and strategic insight. Take the time to choose well.
