Climate change is a serious problem that affects us all. There is strong evidence that human emissions of greenhouse gases are changing the world's climate. The main greenhouse gas is carbon dioxide (CO2), produced when we burn fossil fuels like coal, oil and gas for energy.

Over 40 per cent of CO2 emissions in the UK come directly from what we do as individuals; for example, heating and using electricity in our homes - and driving vehicles. Flights are the next biggest source of individuals’ CO2 emissions.

Everyone contributes to climate change

Everyone has a carbon footprint - it's your own personal measure of how much carbon dioxide you create and how much you contribute to climate change.
