The Carbon Footprint Calculator has been designed to help UK based SMEs measure their corporate emission footprint following GHG Protocol Guidance, including direct emissions from fuel and processes (Scope 1 emissions) and those emissions from purchased electricity (or Scope 2 emissions) for the assets they operate.

The following tool is not a complete evaluation of an organisational footprint. It only includes selected emission sources, common to the majority of SMEs using an operational control approach.

In order to calculate the organisation’s footprint, you will need the following information for your chosen reporting year:

• Fuel consumption - Fuel consumed by the organisation in its sites and owned vehicles. This can be natural gas, diesel or LPG. You may find this information in bills, fuel card data or meters
• Energy consumption - Electricity used in your sites. You may find this information through meter readings, utility bills, or automatic meter readings
• Top ups made to air conditioning units - Many refrigeration, fire protection and air conditioning equipment contain a type of F gas (Fluorinated greenhouse gas), which has a large carbon footprint. Please include the type and quantity of top up that has been done during the reporting year. You can find this information in the service sheets provided by your air conditioning or refrigeration contractor

It is important that the reported data covers the chosen 12 months of data. If you don’t have data exactly for the whole year, you should estimate the consumption using the average energy or fuel consumed per month.

Please note that there can be seasonal changes in energy demand due to production levels, need for heating / cooling and use and replacement of equipment.
