Emissions of Carbon Dioxide (CO2)

Postby fwiggins » Tue Jun 07, 2011 12:41 pm

Carbon dioxide (CO2) is a colourless, odourless and non-poisonous gas formed by combustion of carbon and in the respiration of living organisms and is considered a greenhouse gas.

Carbon dioxide (CO2) is the most common greenhouse gas produced by anthropogenic activities, accounting for about 60 per cent of the increase in radiative forcing since preindustrial times (IPCC, 1992). By far the largest source of CO2 emissions is from the oxidation of carbon when fossil fuels are burned, which accounts for 70-90 per cent of total anthropogenic CO2 emissions. When fuels are burned, most carbon is emitted as CO2 immediately during the combustion process. Some carbon is released as CO, CH4, or non-methane hydrocarbons, which oxidise to CO2 in the atmosphere within a period from a few days to 10-11 years.
