US transport fuel

[edit / update model]
This category is deprecated. The Greenhouse Gas Protocol methodologies for transport fuel can now be found here

Transport by fuel US 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
Secondly the drill-down CO2eOrCO2 allows the user to specify whether they wish the result to give CO2e emissions, including N2O and CH4 emissions, or CO2 emissions only. The next two drill-downs allow the specification of the transportType and transportSubType. Finally the drill-down '''yearOfManufacture''' specifies the age for certain vehicles. The fuelQuantity used during the journey is then entered as a profile item value.

The algorithm returns either CO2 or CO2e emissions depending on the choice made in the CO2eOrCO2 drill-down.

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 or those of CH4 and N2O. Therefore, the CO2 emissions for pure 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.
