The purpose of the greenhouse gas (GHG) conversion factors is to
help businesses convert existing data sources (e.g. utility
bills, car mileage, refrigeration and fuel consumption) into CO2
equivalent emissions by applying relevant conversion factors
(e.g. calorific values, emission factors, oxidation factors).
Carbon Calculated have standardised this information and made it
available to developers via a RESTful API. |Auteur||Author not
