Carbon footprint calculator

Estimate your annual emissions and identify the sources contributing most to your carbon footprint.

Enter annual usage and a credible emission factor for each available source. Leave excluded sources blank. Do not count both fuel and distance for the same journey.

Electricity — annual kWh
Diesel — annual litres
Travel — annual km

Use electricity factors matching your country and data year, and fuel or travel factors matching the activity. No factors are prefilled because they change the result.
