With our tree carbon calculator, you can make a simple measurement of a tree on your property, in your school, or down at your local park, and be given an estimate of just how much carbon is stored in that tree.

Also on this website, we can give you an idea of how much carbon dioxide your day-to-day activities are contributing to the atmosphere, so that you can get a feel for just how many trees are needed to offset Australia's carbon dioxide emissions.

Why do we need to know how much carbon is stored in trees?
