Emitwise
Emitwise is a London-based carbon accounting and Scope 3 reporting platform that uses AI to help large enterprises measure, manage, and reduce their product carbon footprint (PCF) and supply-chain greenhouse-gas emissions. The platform ingests spend data, activity data, and supplier information, auto-classifies suppliers, and produces audit-ready emissions reporting aligned with the GHG Protocol (Scope 1, 2, and 3) and frameworks such as CDP and CSRD. The Emitwise developer API at api.emitwise.com exposes facilities, projects, activity-data files, schema metadata, and aggregated supplier emissions data so customers can integrate carbon accounting into procurement, ERP, and sustainability reporting systems. Access is granted per-customer through Emitwise CSMs; API keys are generated from the Company settings area of the dashboard. In July 2025, Emitwise was acquired by Green Project Technologies; the Emitwise platform and team are now part of Green Project's end-to-end decarbonization solutions, while the existing Emitwise developer portal and API endpoints remain live for customers.
