Description

These conversion factors are produced by the UK Government to help companies calculate greenhouse gas emissions from a range of activities, including energy use and transport activities.


These conversion factors enable you to convert activity data (e.g. litres of fuel used, tonnes of waste sent to landfill) into kg of CO2 equivalent (CO2e).

The conversion factors should be used alongside the 'Guidance on how to measure and report your greenhouse gas emissions' (http://www.defra.gov.uk/environment/economy/business-efficiency/reporting//).

This set of conversion factors is the definitive data set for calculating GHG emissions where fuel/energy use and other activity data is known. Companies are encouraged to use the emissions factors with the Defra/ DECC guidance to help calculate their emissions and report them in their annual reports. This will provide a robust foundation to report on GHG emissions. It also contains a comprehensive list of transport modes which allow individuals and fleets to calculate emissions from transport. Although this is an excellent resource for CO2, CH4 and N20 emissions from road transport, no local air pollutant emissions estimates are included. Also in relation to transport, standard road transport conversion factors are provided but not factors for individual models of vehicle. Due to the time lag required to collect data, the latest grid average electricity factors are based on GHG emissions from major power stations from two years previously.
