How It Works




HOW MUCH IS A TONNE ANYWAY?

The term 'tonne' refers to a metric tonne of carbon dioxide (CO2). By protecting forests, we are preventing millions of tonnes of CO2 from entering our atmosphere. For instance, one single mature tree in the Congo rainforest would emit as much as 18 tonnes of CO2 if it is cut down*. Compare some common everyday activities and the rough equivalent of their correlating CO2 emissions below**:
