How much carbon is your business actually emitting?

Work out your organisation's estimated Scope 1, 2 and 3 emissions in three short steps, using your own energy, fuel and spend figures.

Step 1 of 3

Direct emissions — fuel burned on-site or in company vehicles over the last 12 months. Leave anything that doesn't apply blank.

Check a recent gas bill — usually shown in kWh.

This calculator gives an indicative estimate using standard UK emission factors. It is not a substitute for a full, verified carbon assessment.
