Carbon calculator

You can use our Carbon calculator to work out your household's emissions. It's fun, it's easy and you might be surprised by the results. If you don't know what your figures are, you can use the National averages.

Based on the results, we will give you a suggested donation which will offset your emissions by contributing to our projects.
