Detailed explanation-1: -Coal-fired power plants (CPPs) are one of the largest contributors to air pollutant emissions in China. The sulfur dioxide (SO2), nitrogen oxide (NOx) and fine particulate matter less than 2.5 m in diameter (PM2.5) emissions of CPPs accounted for 33%, 33% and 6% of national total emissions in 2010, respectively [1].
Detailed explanation-2: -China is rich in fossil fuel resources and doesn’t resist exploiting them even though it also invests in green energy sources (mainly solar). As a result, large amounts o greenhouse gases with particulate matter reach the atmosphere. Another reason is China’s role in global trade.
Detailed explanation-3: -Coal impacts: air pollution When coal is burned it releases a number of airborne toxins and pollutants. They include mercury, lead, sulfur dioxide, nitrogen oxides, particulates, and various other heavy metals.
Detailed explanation-4: -One of the major sources of air pollution in China and India is from sulfur-dioxide emissions. The major contributor to the sulfur-dioxide emissions is due to increased coal consumption in the industrial sectors in both countries. More than 70% of China’s energy still comes from brown coal, the dirtiest fuel of all.
Detailed explanation-5: -Mainly because of its use of coal, China emits almost a third of all man-made greenhouse gases-more than the United States, Europe and Japan combined.
