Thousands of scientifically-vetted emission factors across hundreds of regions and sources, one single database.


Up-to-date and transparent emission factors, covering carbon dioxide and all constituent gases. Sourced from reputable government agencies and institutions.
Data from 80+ datasets is now easily ingestible in a structured format, enriched with metadata such as validity year, source, CO2e calculation method, region, quality flags and LCA activity.

Our data is verified through expert manual review and AI-driven outlier detection, audited by our in-house scientists, and overseen by a panel of respected environmental experts.
All of Climatiq’s emission factors are compliant with the GHG Protocol and expressed in CO2e (Carbon Dioxide Equivalent), taking into account Global Warming Potential in 100 years (GWP 100).
