ACT ON CO2 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. Ways in which the government will help people act There are many ways the government is planning to help you act on reducing CO2 emissions - now and in the future. This means working in partnership with businesses, organisations and manufacturers. ‘My CO2‘ climate change film This short film shows how energy use in your home creates CO2 emissions, and how we can all reduce our emissions to help tackle climate change.
