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.
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.
Your Complete CSRD Reporting Platform
With the CSRD now in effect for large companies across Europe, the demand for structured, auditable sustainability reporting has never been greater. Horizon ESG serves as a complete CSRD reporting platform, guiding your team through double materiality assessments, ESRS data collection, and audit-ready disclosures. AI-powered gap analysis ensures nothing is missed, while built-in evidence linking satisfies assurance requirements from day one.
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 AI output is transparent, editable, and traceable. 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.
Is the CSRD reporting platform suitable for companies outside Europe?
Yes. While Horizon ESG provides comprehensive CSRD/ESRS support, the platform also covers TCFD, ISSB, GRI, SECR, and SFDR frameworks. Organisations based outside Europe that need to comply with CSRD due to their 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.
