The platform combines data collection workflows, regulatory compliance engines, carbon accounting, and benchmarking into a unified product suite organised around four modules (Collect, Comply, Report, Improve) plus specialised add-ons for Carbon Accounting and CSRD Compliance. Underlying technology includes 70,000+ verified emission factors from DEFRA, US EPA, and Climatiq, 250+ preset data points with unlimited custom metrics, API integrations with Power BI, Tableau and data warehouses, an MCP connector for feeding verified ESG data into enterprise AI tools (Claude, Gemini), and embedded agentic AI for 24/7 in-workflow support.
