Climatiq

Climatiq provides a developer-first API for carbon accounting and emissions calculations. The platform packages a curated emission-factor database together with calculation endpoints that turn activity or spend data into auditable CO2-equivalent estimates aligned with the GHG Protocol. Capabilities span search across the factor catalog, generic activity-based estimation, and purpose-built endpoints for travel, freight (GLEC), energy, cloud computing, procurement, and the EU Carbon Border Adjustment Mechanism. The API is keyed (Bearer token) and hosted at api.climatiq.io.
