How to use this table

Find the row closest to your electricity used and read across to the co₂ emissions. For a value between two rows, the real figure sits between them — or enter your exact numbers in the kWh to CO2 Calculator for a precise answer.

Need a value that is not in the table? — the kWh to CO2 Calculator does it instantly, for free, with the formula and a worked example built in.
