KEY ESG is the platform where sustainability teams and their business colleagues collect, validate, analyse, and report ESG data in one place and connect it to the decisions that actually drive the business forward. Most ESG programmes fail not because companies don't care, but because the work stays fragmented across spreadsheets, inboxes, and disconnected tools, and because sustainability data rarely reaches the people who could act on it. With KEY ESG, sustainability teams and their colleagues across finance, operations, and the business collect data collaboratively, with AI-powered in-platform validation catching errors and anomalies before they reach a report or an auditor. Shareable reports can be produced in minutes. Dashboards give the whole organisation a live view of performance, and the target and action planning module means ESG goals get tracked with the same discipline as financial ones. The platform provides the context for smart ESG decisions: understanding trade-offs, evaluating the impact of different courses of action, and aligning sustainability targets with business goals. Coverage includes full GHG-aligned carbon accounting across Scope 1, 2, and 3, and support for SFDR, EDCI, CSRD, GRI, TCFD, and custom frameworks. Data can be collected and reported at group, subsidiary, entity, or project level. For organisations using enterprise AI tools, the KEY ESG MCP connector allows Claude, Copilot, and Mistral to query your ESG data directly, so your AI tools can answer questions about sustainability performance with validated, audit-ready data behind them.
