Everyone has a carbon footprint

A carbon footprint is shorthand for our impact on the planet. Almost everything we do from how often we fly, to the type of shampoo we use releases greenhouse gases into the atmosphere. Adding up these actions over a year gives your individual carbon footprint.

Your footprint is measured in 'carbon dioxide equivalent' or CO2e. This refers to all the greenhouse gases like carbon dioxide, methane and nitrous oxide released as part of your everyday life.

You can reduce yours with a few simple actions

Things like eating less meat or taking fewer flights will shrink your footprint straight away. But some habits are hard to change. So you can offset the CO2e they produce by supporting verified carbon reduction projects. These include protecting rainforests or supporting clean energy in other parts of the world.
