All About Carbon Dioxide
Carbon is an element that's found all over the world and in every living thing. Oxygen is another element that's in the air we breathe.
Carbon Dioxide (CO2) - Carbon Dioxide is a colorless, odorless gas that naturally exists in the earth's atmosphere. The major source of man-made CO2 emissions is from the combustion of fossil fuels.

carbon dioxide (CO2): the major greenhouse gas (see below); increasing amounts of CO2 are being released by burning fossil fuels or dead plant matter (including deforestation (see below).
Carbon dioxide is produced whenever fossil fuels or wood are burnt. Each tonne of oil burnt produces over 3 tonnes of CO2. Road transport and electricity generation rely on the burning of fossil fuels releasing carbon dioxide into the atmosphere.
