What emission factors do we use in the database?

Our paid emissions database includes emission factors collected from public sources and directly from companies. We only collect non-corporate emission factors from the best available sources, such as research institute publications and scientific articles. We carefully review the constraints and assumptions underlying the calculation of each emission factor. DNV has validated the OpenCO2net data collection process.

What is the difference between the paid and the free emissions database?

OpenCO2 emission database is one of the most extensive in Europe and is designed for the needs of companies.

The free emissions database is a limited version of our extensive emissions database. You have access to the most common emission factors associated with everyday life.
