What are the main causes of air pollution in China?

China consumes almost as much coal annually as all other countries combined, and coal burning in the country is the biggest source of both air pollution and greenhouse gas emissions, the leading cause of climate change. Chinese cities are among the most polluted in the world.

Why does China cause pollution problems?

The immense urban growth of Chinese cities substantially increases the need for consumer goods, vehicles and energy. This in turn increases the burning of fossil fuels, resulting in smog. Exposure to Smog poses a threat to the health of Chinese citizens.

What are 3 causes of pollution in China?

Sources of the air pollution in Northeastern China

Six main sources have been identified for smog in Beijing: soil dust, coal combustion, biomass burning, traffic and waste incineration emission, industrial pollution, and secondary inorganic aerosol (Zhang, 2013).

How does China have more air pollution?

The primary reason for China’s polluted air is emissions from coal plants. The rate at which the country consumes coal is monumental. Even as recently as 2016, coal generated 62% of China’s electricity. All in all, it’s estimated that 1 out of every 4 metric tons of coal humanity burns are burned in China.

How can we stop pollution in China?

Reduce air pollution emissions through pollution abatement measures including installing equipment to remove particulate matter, flue gas desulfurization, and denitrification, replacing coal with natural gas, and expanding clean energy vehicles.

When did China’s air pollution start?

Urban air pollution monitoring started as early as the mid-1970s in China. Currently, more than 350 cities conduct routine urban air quality monitoring of the pollutants SO2, TSP, and NOx. The 103 municipal atmospheric monitoring stations with 470 monitoring sites form China’s national air monitoring system (NAMS).
