What is carbon dioxide?
Carbon dioxide (CO2) is a natural gas that is produced by most living organisms, including humans and animals. It is produced when we breathe out and is needed by plants to aid their growth and development.
As well as being an integral part of everyday life, CO2 is a by-product of burning fossil fuels such as coal and gas for energy. This is one of the major contributors to global climate change.
In 2019, the UK committed to reaching net zero by 2050 and reducing our CO2 emissions will play a large role in achieving this target.
