Factory emission is relatively less or actually declined.
Actually 70% of all electricity produced in China in 2009 was consumed by the manufactoring and industrial sector and it is getting worse.
Chinese industry scores very poorly in energy efficiency. Chinese steel factories use one-fifth more energy per ton than the international average. Cement needs 45 percent more power, and ethylene needs 70 percent more than average, the World Bank says[2]. A lot of the pollution in China nowadays is generated for producing the cheap products that fill stores in the United States and Europe.
Damaging air pollutants include sulfur dioxide, particulate matter—a mixture of extremely small particles and water droplets—ozone, and nitrogen dioxide. China accounts for roughly one-third of the global total for these pollutants, according to Krzyzanowski.
The combustion of fossil fuels—whether to power China's many automobiles, its burgeoning factories, or its expanding megacities—is a primary source of outdoor air pollutants.
Coal is the number once source of air pollution in China. China gets 80 percent of electricity and 70 percent its total energy from coal, much of it polluting high-sulphur coal. Around six million tons of coal is burned everyday to power factories, heat homes and cook meals. Expanding car ownership, heavy traffic and low-grade gasoline have made cars a leading contributor to the air pollution problem in Chinese cities.
