Your carbon footprint is the total amount of carbon dioxide you emit. Virtually everything you do has a carbon footprint, such as driving a car, disposing waste, using electricity and traveling by plane. This is important because carbon dioxide, along with other greenhouse gases, is responsible for increasing the world’s average temperature (climate change). This is a good guide if you want to learn more.
Reducing the amount of greenhouse gases we emit is important for the future of our planet, because it will help us limit the extent of climate change.
