Horizon ESG

Horizon ESG is a UK-based ESG reporting platform built around a simple idea: sustainability data should be planned, managed and reported with the same rigour finance applies to its numbers. The platform covers the full cycle - emissions tracking across Scopes 1, 2 and 3, target and initiative management, framework-aligned disclosure and audit-ready evidence - in one structured workspace.

Who it's for. Horizon ESG is designed for mid-market companies, particularly the thousands that fell outside CSRD scope after the 2026 Omnibus changes but still face ESG data demands from customers, banks, insurers and tender processes. For them the deadline is a tender date rather than a regulatory one, and the platform is built to answer exactly that: structured, evidenced responses to value-chain data requests, aligned to the VSME standard those requests are capped at.

Frameworks. One evidenced dataset feeds multiple regimes: CSRD/ESRS for companies still in scope, the voluntary VSME standard, the new UK SRS S1 and S2, TCFD, SECR, the GHG Protocol and GRI. Enter the data once, report it wherever it's demanded.

Audit-ready by design. Assurance providers now test documentation, traceability and controls, and Horizon ESG is built for that scrutiny. Every figure carries its source, owner and timestamp; calculation methodologies are documented; changes are versioned. The result is a reporting process that stands up to limited assurance from day one.

Nova, the intelligence layer. Nova drafts disclosure text, answers inbound customer questionnaires, checks data quality and flags gaps - and it shows its working. Every Nova output is sourced, labelled, editable and human-approved, recorded in the same audit trail as manual entry. Practical AI that improves data quality, insight and control, without ever asking an auditor to trust a black box.

Carbon accounting. Activity-based emissions calculation with a maintained factor library, location- and market-based Scope 2, supplier data collection for Scope 3, and science-based target tracking with progress reporting against initiatives.

Getting started. Self-serve free trial (no credit card), guided onboarding, and UK-based support. Pricing scales for mid-market budgets rather than enterprise procurement cycles.

Horizon ESG: sustainability, planned, managed and reported - with the evidence to prove it.
