CSRD may no longer apply to you. Your customers still will.
Since 18 March 2026 CSRD requires 1,000 employees and €450m turnover, cutting scope from around 50,000 companies to roughly 5,000. The data requests from customers, lenders and insurers have not gone anywhere. Check where you stand in ten minutes.

Which problem are you solving?
Sustainability reporting has split into separate jobs, usually held by different people, and most organisations are now doing more than one of them. Horizon ESG is built so they all work on the same data.
“I am drowning in customer questionnaires”
The regulator stopped being your biggest correspondent. Customers, banks, insurers and procurement portals took over, and none of them use the same form.
- Answer every request from one evidenced dataset
- Know exactly how far a customer can push, and cite it
- Nova assembles the answer, you review it
- Live in two to four weeks, without consultants
“These numbers need to survive an audit”
Assurance turned sustainability disclosure into a controls problem. That puts non-financial data under the standard you already apply to everything that reaches a published report.
- Datapoint-level lineage back to source documents
- Immutable change log and enforced segregation of duties
- Prior periods reproducible on the original methodology
- Published pricing, so budgeting is not a sales process
“We are growing, and so is what we report”
Each year adds another obligation you can already see coming, and a spreadsheet that carried last year will not carry a new framework, a first sustainability hire and a question from your auditor.
- One dataset behind CSRD and ESRS, ISSB, GRI, TCFD, SECR and SFDR
- Add the next framework by mapping data you already hold
- Roles, approvals and version history that survive a handover
- Bring last year’s spreadsheets in as your baseline, not a fresh start
Most organisations have more than one of these and solve them separately, which is how a figure in a customer questionnaire ends up disagreeing with the one in the annual report. Horizon ESG holds a single evidenced dataset, so the sustainability team answers requests from it, finance signs off the same numbers, and the next framework is a mapping rather than a fresh start.

ESG Reporting Software Built for Modern Sustainability Teams
Horizon ESG is a comprehensive ESG reporting software platform that brings together every element of your sustainability programme in one place. Instead of juggling spreadsheets, email chains, and disconnected tools, your team works in a unified environment where carbon data, compliance disclosures, strategic targets, and AI-powered insights are all connected.
Choosing a platform is a significant decision, so we have published an open comparison of the best ESG reporting software for 2026, covering eight platforms including Workiva, IBM Envizi, Sphera, and Watershed alongside our own.
As a purpose-built sustainability reporting software, Horizon ESG understands the specific requirements of frameworks like CSRD, GHG Protocol, TCFD, and ISSB. Every template, calculation, and workflow has been designed by ESG professionals for ESG professionals – which means less time configuring tools and more time driving real sustainability outcomes.
Built for the Assurance Engagement
Assurance is a documentation exercise before it is a numbers exercise. Your provider will test the chain from a published figure back to its source, the controls over who changed what, and whether your methodology is written down. Horizon ESG links evidence at datapoint level, keeps an immutable change history, enforces separation between whoever enters data and whoever approves it, and can reproduce a prior year on the methodology that applied at the time. Our comparison of audit-ready ESG platforms sets out what to demand from any vendor on this.
Answer Customer and Lender Data Requests Without Starting Over
For most mid-sized companies the pressure now comes from the value chain rather than the regulator. Customers, banks and insurers ask for ESG data on their own timetables and in their own formats, and a tender deadline is less forgiving than a reporting one. Horizon ESG holds one reusable dataset that serves many request formats, so answering the next questionnaire is a matter of hours rather than weeks. Our note on the value chain cap explains what larger customers can and cannot require of you.
CSRD and ESRS, Where They Still Apply
Since the Omnibus I Directive came into force in March 2026, CSRD applies only to companies exceeding 1,000 employees and €450 million turnover, and the revised ESRS cut mandatory datapoints by more than 60 per cent. If you are still in scope, Horizon ESG is a complete CSRD reporting platform covering double materiality, ESRS data collection and assurance-ready disclosures. If you are not, the same dataset serves UK SRS, SECR, ISSB and the questionnaires your customers send.
Carbon Accounting You Can Trust
Accurate carbon measurement is the foundation of credible sustainability reporting. Our carbon accounting module calculates Scope 1, 2, and 3 emissions using GHG Protocol methodology, with AI-assisted emission factor matching and transparent calculation methods. The result is a carbon inventory that withstands external audit and feeds directly into your compliance reports.
AI That Saves Time Without Cutting Corners
Horizon ESG’s AI automation handles the most time-consuming aspects of ESG reporting – data ingestion, validation, estimation, and narrative drafting – while keeping humans firmly in control. Every output from Nova, our built-in intelligence layer, is sourced, labelled, editable and recorded in the same audit trail as manually entered data, so an assurance provider can see exactly how a figure was reached. Your sustainability reporting software should make your team faster, not replace their judgement, and that is exactly what Horizon ESG delivers.
From Targets to Tangible Progress
Setting sustainability targets is only the beginning. Horizon ESG’s ESG planning module connects your strategic goals to operational initiatives, assigns clear ownership, tracks progress with real-time dashboards, and feeds outcomes directly into your compliance reports. It is the missing link between sustainability ambition and demonstrable results.
Frequently Asked Questions
What makes Horizon ESG different from other ESG reporting software?
Horizon ESG connects carbon accounting, compliance reporting, target management, and AI automation in a single integrated platform. Most competitors offer only one or two of these capabilities, forcing teams to manage data across multiple tools. Our connected approach eliminates data silos, reduces manual work, and ensures consistency across all your sustainability disclosures.
Does CSRD still apply to my company after the Omnibus?
Only if you exceed 1,000 employees and €450 million turnover, both tests together. The Omnibus I Directive came into force on 18 March 2026 and cut scope from around 50,000 companies to roughly 5,000. Most organisations that were preparing for CSRD are now out of direct scope, but still receive data requests from customers and lenders who remain in. Horizon ESG covers CSRD/ESRS alongside UK SRS, ISSB, TCFD, GRI, SECR and SFDR, so the same dataset serves whichever applies. Organisations outside Europe with EU operations – or that want to align with global best practices in sustainability reporting – will find the platform fully capable of meeting their needs.
How quickly can we get started with the sustainability reporting software?
Most organisations are operational within two to four weeks. Horizon ESG includes pre-built templates, guided onboarding, and data migration support that accelerate setup. You can start with a free trial to explore the platform, or book a demo to see how the ESG reporting software would work for your specific requirements.
