Other regional transport fuel

This data is sourced from the GHGP worksheet GHG emissions from transport or mobile sources v2.0. This category allows the user to calculate emissions from specified journey by monitoring the amount of fuel used. Firstly the user selects the drill-down fuelType from the following options.

• jet fuel
• aviation gasoline
• gasoline/petrol
• diesel
• residual fuel oil
• lpg
• cng
• lng
• e85 ethanol/gasoline
• b20 biodiesel/diesel

The algorithm returns kg CO₂ emissions for the specified journey.

Biomass fuel

The GHG protocol requires CO₂ emissions from biomass fuels to be reported on differently, due to the fact that the CO₂ released from biomass fuels has only recently been sequestered from the atmosphere and so does not constitute a net increase in CO₂, unlike fossil fuel emissions. Therefore, the CO₂ emissions for ethanol and biodiesel are not included here, but can be found in the biomass subcategory. There are two mixed fuel entries in this category - E85 and B20. These are a mixture of biofuel and fossil fuel. Therefore, this category contains the CO₂ emitted from the fossil fuel constituent, with the biomass fuel emissions given in the biomass subcategory. If the user wishes to calculate their total emissions, including biomass CO₂ they should use both categories in combination.
