Climate change is increasingly big news and more than ever people are conscious of the need to make changes to their lifestyles and looking for the most effective ways of doing it. Calculating your carbon footprint will give you a direct measure of your impact on the planet and will allow you to see which areas of your life are most in need of a carbon diet. The average person in the UK has a carbon footprint of 9.4 tonnes. Experts say that we would all need to reduce our carbon footprint to 2.5 tonnes or less to prevent dangerous climate change.
