But it's also the by - product of fossil fuel combustion, and when a refinery or power plant reduces its greenhouse gas emissions (by becoming more energy - efficient, for example), it also releases fewer smog - forming chemicals like nitrogen oxides,
less of the sulfur dioxide and soot that can irritate lungs and cause respiratory disease, and fewer toxic emissions linked to cancer and neurological disorders.

Natural gas is much more environmentally friendly than coal, which continues to be the mainstay
of electricity production around the world and in the U.K. Gas emits
less than half the CO2 per kilowatt hour produced, and it emits much lower amounts
of other pollutants like nitrous oxide,
sulfur dioxide, black carbon, carbon monoxide, mercury, and particulates.
According to this chart PEF, and even RDF and unprocessed MSW, generate significantly
less Sulfur Dioxide (SO2) the cause
of «Acid Rain» than when using Coal.
When coal is burned due to combustion that is more or
less completed the result is different levels
of energy (B.T.U.'s), and different levels
of air emissions (
Sulfur Dioxide - SO2, Mercury - Hg), greenhouse gases (Carbon
Dioxide CO2, Nitrogen Oxide - NO3), and amounts
of ash that can potentially be toxic dependent on the conditions within the combustion chamber and ash that can or can not be used in a secondary market (ex.
