Guide: Calculate your carbon footprint

The Carbon Trust has developed an online carbon footprint calculator specifically for SMEs to help manage and report energy consumption and carbon emissions.

The Carbon Trust has developed an online carbon footprint calculator specifically for SMEs to help manage and report energy consumption and carbon emissions. 

The Carbon Footprint Calculator has been designed to help UK-based SMEs measure their corporate emission footprint following internationally-recognised standards.

It differentiates between ‘direct emissions’ from fuel use and processes (also known as Scope 1 emissions) and ‘indirect emissions from purchased electricity (Scope 2 emissions). 

The calculator is free to use and does not require a login. 

The Carbon Trust has also produced a 27-page guide to carbon footprinting in more detail, taking in organisational, supply chain and product footprints and how to measure and communicate them.
