Scientifically vetted emission factors. Open to all.

Climatiq's GHG emission calculation engine is powered by the largest open database of vetted emission factors.

Our data in numbers

Choose among thousands of up-to-date and verified emission factors in our open database or import your own to accurately calculate the carbon emissions of any activity.

All of Climatiq’s emission factors are compliant with the GHG Protocol and expressed in CO2e - i.e. Carbon Dioxide Equivalent, taking into account GWP 100, i.e. Global Warming Potential in 100 years.
