Fossil fuels, even when burned perfectly (natural gas, or methane, burns the best) release carbon dioxide which is a greenhouse gas causing dangerous global warming. Most fossil fuels also release smoke (leading to smog), and they may also release sulfur oxides and nitrogen oxides which contribute to acid rain.  The burning of fossil fuels (coal, oil and natural gas) in  industry, transport and the generation of electricity releases  carbon dioxide (CO2) which is cau â¦ sing global warming.
What really makes fossil fuels controversial is the pollution they create. Even the most ardent supporter of continued use of fossil fuels will admit that they produce pollutants that are harmful to the environment.
