Calculate your carbon

16.12.2005 There are lot of carbon calculators on the web. We particularly like this one produced by COIN, because it's UK-based and includes the climate implications of what we buy and what we eat.

COIN also has a net dowloadable spreadsheet that will help you work it out without a calculator.

Alternatively there's a more international calculator from the World Resources Institute which works well and gives results directly on the screen.
