  • Does Greenly take physical and monetary flows into account?

    The accounting export file will allow us to obtain conversions of $ into CO2 via the ADEME emissions factors. When we have identified items with high emission factors, we will complete them with physical quantity measurements and work with more physical data from your organization (MW...).
