The category /transport/lgv/generic/ghgp/heavyduty/other contains data on emissions associated with heavy duty trucks in non-US or UK contexts sourced from the GHGP Protocol, and allows the user to calculate emissions depending on the type and fuel of the vehicle.
Firstly the type of vehicle is specified, using the vehicleType drill-down, from either 'rigid' or 'articulated'. Then use the fuelType drill-down to specify the fuel type from the following options.
The distance is then set as a profile item value.
The algorithm returns kg CO2 emissions for the vehicle/fuel type and distance specified.
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 N2. Therefore, the CO2 emissions for ethanol are not included here, but can be found in the biofuel subcategory.
