Just days after Beijing passed a plan to fight air pollution, its neighboring city Tianjin has also passed a scheme to make its sky clearer. The program features two short-term goals.

By 2017, the city aims to lower its PM2.5 readings by 25%, and reduce its consumption of coal by 10 million tons per year. Tianjin is also rolling out a gas heating system, to replace the city's coal heating plants.

The program also puts emphasis on limiting vehicle emissions, dust and industrial pollution.
