The system facilitates the reporting to major standards such as the CDP, ISO 14064, ISO 14001, the GHG Protocol (WBCSD/WRI), GRI and more.

Flight emissions

Our factors does not include the RF factor and are therefore smaller (We do include the 9% uplift factor). The reason is because EU ETS does not include it an hence the aviation companies do only report the direct emissions. A lot of companies use numbers directly from these and confusion is therefore less if we exclude RF. But we will add them as an optional choice, if companies wish to include RF.
