China has been cutting pollution in an effort to clean up its air for many years. Being the most carbon-intensive fossil fuel, coal is a major force in carbon-dioxide emissions.

The capital city will continue to cut coal consumption by ending the trade of low-grade bituminous coal for civil use within this year. And four districts (Chaoyang, Haidian, Fengtai and Shijishan) will end coal use altogether by the end of 2017, said the Beijing Municipal Commission of Rural Affairs on Tuesday.

This year, 172 villages in the four districts that rely on coal-fired heating will reduce their use of coal and gradually switch to gas. Each household will reduce the use of coal by 3 tons during the winter season. Nearly 200,000 villagers will benefit from the project, which will save some 600,000 tons of coal.

Beyond the first four districts, Beijing is also going to promote a "No Coal" campaign in Tongzhou, the sub-capital center, as well as two heavily polluted areas, Daxing and Fangshan. This information comes from the Ministry of Environmental Protection.

By 2017, Beijing plans to cut annual coal consumption by 13 million metric tons from the 2012 level in a bid to slash the concentration of pollutants.

Last year, 1,500 people in six villages of Caiyu town finished construction of a pipeline. And this year another 1,200 people will benefit from it.

As far as the cost of using gas rather than coal, the man said that he has to spend about 2,000 yuan on three to four tons of coal for heating, which is more expensive than the current cost of gas, and that doesn’t even take into account the government subsidy to promote gas heating.
