Horizon ESG

Horizon ESG — ESG Reporting & CSRD Compliance Platform

Horizon ESG is a sustainability reporting platform for UK and EU mid-market companies that connects carbon accounting, compliance reporting, target tracking, and AI automation in a single system. It is purpose-built for teams facing their first CSRD/ESRS reporting cycle without enterprise budgets or large sustainability teams.

Carbon accounting

Calculates Scope 1, 2, and 3 emissions using GHG Protocol methodology across all 15 Scope 3 categories, with AI-assisted emission-factor matching, supplier data-collection workflows, spend-based estimation, and transparent, traceable calculations.

CSRD & ESRS compliance

Guides teams through double materiality assessment, ESRS data collection, and audit-ready disclosures. Covers all 12 ESRS standards with pre-built templates for every mandatory and voluntary disclosure point.

Multi-framework support

Beyond CSRD/ESRS, the platform supports TCFD, ISSB, GRI, SECR, and SFDR from the same dataset — removing duplicate data entry across frameworks.

AI automation

Automates data ingestion, validation, estimation, and narrative drafting while keeping reviewers in control. Horizon ESG states this reduces manual reporting effort by up to 70%.

Audit-readiness

Provides financial-grade controls, full evidence trails, and traceable data at every step, prepared for external assurance without last-minute reconciliation.

Differentiators

Mid-market pricing and onboarding rather than enterprise-tier complexity; an integrated carbon-to-disclosure workflow (not separate carbon and reporting tools); and UK/EU regulatory focus including post-Omnibus CSRD and UK SRS.
