The flue gas emissions from conventional coal-fired power plants also include carbon dioxide (CO2) which is the major component of the flue gas produced in the combustion of coal. It is not a pollutant in the traditional sense and it is essential for all plant life on Earth through photosynthesis.
However, carbon dioxide is a greenhouse gas considered to have a major role in global warming.

Carbon dioxide
According to a 2005 report from the World Wide Fund for Nature (WWF), coal-fired power plants produce more carbon dioxide per unit of electricity generated than any other type of power plant. Electricity generation is responsible for 41% of U.S. manmade carbon dioxide emissions.[5] Research has indicated that increased concentration of carbon dioxide in the atmosphere is correlated with a rise in mean global temperature, also known as global warming.[6] The International Panel on Climate Change (IPCC) states that, to avoid climate change impacts, Annexe 1 (developed) countries must reduce greenhouse gas (GHG) emissions by between 25 and 40% by 2020. The technology for carbon capture and storage of emissions from coal fired power stations is not expected to be available on a economically viable commercial scale by 2020.Template:Fact
