Frameworks Supported by Horizon ESG
Horizon ESG is a comprehensive sustainability reporting platform that covers all major disclosure frameworks used across the UK and Europe. Our platform provides native support for the following standards.
- CSRD / ESRS - full European Sustainability Reporting Standards coverage with double materiality tools and XBRL-ready output.
- TCFD - structured reporting across all four TCFD pillars with climate scenario analysis support.
- GRI - Global Reporting Initiative standards mapping for comprehensive stakeholder-oriented disclosures.
- SECR - Streamlined Energy and Carbon Reporting for UK-qualifying companies with DEFRA emission factor integration.
- ISSB (IFRS S1 and S2) - International Sustainability Standards Board alignment for investor-focused disclosures.
- CDP - automated CDP questionnaire responses using data already captured in the platform.
Benefits of Switching from Spreadsheets to Software
Many sustainability teams still rely on spreadsheets for ESG data management. While spreadsheets may work for simple disclosures, they quickly become a liability as reporting requirements grow more complex and demand greater rigour. If you have reached that point, our ESG reporting software comparison covers eight platforms and who each one suits.
- Time savings: Organisations using sustainability reporting software typically reduce reporting time by 40 to 60 percent compared to manual spreadsheet processes.
- Data accuracy: Built-in validation rules, automated calculations, and verified emission factors eliminate the formula errors common in spreadsheets.
- Collaboration at scale: Collect data from dozens of contributors across departments and geographies through a centralised platform rather than emailing files back and forth.
- Regulatory readiness: When frameworks update or new regulations take effect, your sustainability reporting software updates automatically so you are always working against the latest requirements.
- Stakeholder confidence: Board members, investors, and auditors have greater confidence in data produced through a governed, auditable ESG reporting tool.
How Horizon ESG Works
