Unless you plan to stay in bed every day (with the heating and lights off) everyday activities, including driving, heating your home, cooking your supper, or flying, produce carbon dioxide and other greenhouse gases, which contribute to climate change. There are lots of things you can do to reduce your carbon footprint, such as cycling and getting the train more often, insulating your home, turning your heating down, using energy efficient light bulbs, or doing your washing at 30 degrees instead of at 40.

You can also offset your carbon emissions. With carbon offsetting you can pay a certain amount of money to a project, which reduces or removes the equivalent amount of CO2 being produced, and therefore there is no net gain of CO2 to the atmosphere, from your flight or other activity.
