Generic car transport
The category Generic car transport contains data associated with the greenhouse gas emissions of representative car types, e.g. 'small, diesel' or 'large, petrol' cars, sourced from the EPA in the US, and DEFRA, and the VCA in the UK. This category measures CO2 emissions only, and should be considered to represent a useful first point of entry to car-related emissions. This category is used by the UK Government Act On CO2 website.
Generic car transport - DEFRA
The DEFRA Generic car transport category contains the most recently published DEFRA data on greenhouse gas emissions associated with representative car types in UK. The methodology uses distance-based, per passenger 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 car transport contains data on car-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 car transport contains data on car-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, and includes both per vehicle and per passenger functionality.
Specific car transport
The category Specific car transport contains data associated with the greenhouse gas emissions of specific models of motor vehicle sold in the UK and US.
Car transport by band
The category Car transport by band contains data associated with the greenhouse gas emissions of generic size categories of motor vehicles used in the Republic of Ireland.
