The most common greenhouse gas is carbon dioxide, which is released during the burning of fossil fuels – such as driving a petrol-powered car. Burning forests (to use the land for crops or pasture) also adds carbon dioxide to the atmosphere. Carbon dioxide is invisible, but when fuels are burned, soot and nitrogen dioxide are also produced. Together they account for the brown haze associated with urban pollution.
