Our carbon footprint is a measure of how much we effect the environment by the way we live. The bigger our footprint, the more natural resources we are using and damage we are causing!

The size of our carbon footprint is calculated by the amount of carbon dioxide, or CO₂, our activities produce. CO₂ is one of the damaging greenhouse gases that is contributing to global warming or climate change.

The way we choose to travel has a big effect on the size of our carbon footprint.

The petrol we put in cars is a big CO₂ producer. We can reduce the damaging effect CO₂ is having on the planet if we use less of it.

Making fewer car journeys and walking and cycling instead is one way we can do this.
