This Carbon Footprint Calculator was originally developed as part of The Carbon Trust Green Business Fund, the energy efficiency support service for small and medium-sized companies in England, Wales and Scotland.
This Carbon Footprint Calculator looks to help SMEs report their carbon footprint, including some of the most common emission sources. The methodology follows the GHG Protocol guidance and uses predominantly UK emission factors, valid for the reporting year selected by the user.
The results provided by the tool are calculated using emission factors largely provided by DEFRA. These are applicable to UK based businesses only but may be used to estimate emissions in other locations.
The use of this tool does not indicate endorsement, certification or verification of the results by The Carbon Trust.
The emissions associated with one unit of activity vary from year to year, such as per kWh of electricity used. It is therefore advised that you select the relevant reporting year from the dropdown and do not use this to estimate the footprint from previous years. The calculator only supports data from the reporting years 2015 - 2022.
