Generic car transport - DEFRA
The DEFRA Generic motorcycle transport category contains the most recently published DEFRA data on greenhouse gas emissions associated with representative motorcycle types in UK. The methodology uses distance-based emissions factors, requiring the user to specify the distance travelled. This category includes CO2, CH4 and N2O emissions as part of each calculation.
Generic car transport - IPCC
The category IPCC motorcycle transport contains data on motorcycle-associated emissions sourced from the IPCC Guidelines for National Greenhouse Gas Inventories. This category contains data and methodologies for European and US contexts and calculates emissions on per vehicle/per passenger basis, using fuel consumption or a combination of fuel consumption, fuel efficiency and distance.
Generic car transport - GHG Protocol
The category GHGP motorcycle transport contains data on motorcycle-associated emissions sourced from the latest World Resources Institute Greenhouse Gas Protocol (GHGP) documentation. This category includes emissions methodologies for travel in several geographic contexts, on the basis of distance travelled.
