Causes of Acid Rain. Both natural and man-made sources are known to play a role in the formation of acid rain. But, it is mainly caused by combustion of fossil fuels which results in emissions of sulfur dioxide (SO 2) and nitrogen oxides (NO x).an-made sources include emission of sulfur dioxide and nitrogen oxides due to combustion of fossil fuels. Roughly two-thirds of all sulfur dioxide and one-fourth of all nitrogen oxides come from generation of electricity through burning of fossil fuels such as coal.
