The primary category contains data on greenhouse gas emissions associated with numerous types of fuel when burned in the context of transportation. Alternative emissions factors are available for each fuel type, from sources including the IPCC, the UK government agency DEFRA, and the US Energy Information Administration. Users have the option of specifying fuel quantities in terms of energy, volume or mass.
Data for the mobile burning of fuels within this category is taken from parts of several of the Greenhouse Gas Protocol worksheets, including.
- CO2 emissions from transport or mobile sources (v1.3)
- Emissions from employee commuting (v2.0)
- CO2 emissions from business travel (v2.0)
- GHG emissions from pulp and paper mills (v1.3)
- IPCC99, the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (This source is referred to as IPCC99 in the GHGP's worksheet)
- IPCC06, the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (Also used for gasoline/petrol figures for specific engine types)
- IPCC 06, CO2e, ibid, including nitrous oxide and methane emissions.
- EIA, the U.S. Energy Information Administration (EIA). Voluntary Reporting of Greenhouse Gases Program
- Country values for coal - UNEP Guidelines 2000
Note that these figures are for technologies typically used for mobile combustion in transport. For stationary combustion of the same fuels, see Stationary_Combustion
