How does emission calculation work?

We calculate emissions using so-called emission factors. These usually come from authorities of different countries or NGOs. All emission factors are carefully checked and compared with other sources to ensure their plausibility. Visit our API documentation to learn more about the sources of individual "CALCULATION OPTIONS".
