Air pollution in China, how to improve the air quality? (Series 4/4)

First of all, we have to admit that air pollution is a very complicated problem and can not not solved with one solution.

During the Asia-Pacific Economic Cooperation 2014, the people in Beijing experience the best air quality in years. The locals call it "APEC Blue". Seems incredible how the quality has improved, but how the Beijing government achieve this? They enforced a serious of law including, temperately shut down all the factories near Beijing, limit the amount of vehicles on the road, construction sites stopped operating, and more frequent of road-cleaning,

Although the result is undeniable, it is clearly not a sustainable way to improve air quality. China is a developing country that heavily rely on its industrial production, and just shut down all factories will cripple the nation's economy.


However, there are things that can certainly be done.


China needs to reduce the emission from the source. Use renewable, clean energy sources (such as solar , wind, hydro ). Stop using coal. Fuel Pretreatment ( such as coal desulfurization ), improve combustion technology. Plants can also help purified the air. 

There is also the issue of Chinese steel factory over producing their products, these factories need to be regulated.

Local citizens need to use more pubic transport, if driving is unavoidable, install exhaust treatment device to their cars.
