This Carbon Footprint Calculator has been 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 UK based SMEs report their carbon footprint, including some of the most common emission sources. The methodology follows the GHG Protocol guidance and uses UK emission factors, valid for the reporting years 2015 – 2020.
The results provided by the tool are calculated using emission factors provided by DEFRA. These are applicable to UK based businesses only.
The use of this tool does not indicate endorsement, certification or validation of the results shown 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 - 2020.
