Here you can measure your carbon dioxide emissions, compare them with others and find out how to start cutting pollution right away. You can then return in a few months to see how much carbon dioxide you have saved!

Filling in your details shouldn't take you more than 10 minutes. You don't have to calculate anything - you just need to enter some information from your energy bills and about your travel habits.

We've devised a method of calculation to give you as accurate an estimate as possible, in terms that are easily understandable. The calculator is unlikely to be 100% accurate, but it will provide a useful indication of your carbon dioxide emissions.
