Beijing will launch a battle against small coal stoves in family homes and businesses this year, as officials blame consumption of low-quality coal for contributing to winter smog.
Starting this year, Beijing will launch a "large-scale battle" to replace rural coal use with cleaner fuel, city officials said at a meeting on pollution control and coal management on Monday.
Authorities will comb small factories, restaurants, bath houses and hotels in the rural areas to remove their coal-fired stoves, said Zhong Chonglei, a chief inspector with the Beijing Municipal Environmental Protection Bureau.
The official said the campaign would also include a harsher crackdown on sales of low-quality coal that produces more pollutants.
Guo Zihua, an official in charge of the city's rural development, said coal burning will be phased out in all villages in the plain areas by 2020, but rural families that still rely on coal stoves for heating will be urged to use quality coal.
The city closed all coal stoves in central Xicheng and Dongcheng districts by the end of 2015 and plans to make all of its six districts coal-free by 2017, according to Guo.
Small stoves, which consume three million to four million tonnes of coal each year in Beijing's suburban and rural areas, which are not covered by the central heating system, have been blamed for worsening the city's smoggy condition in the winter heating season.
Beijing has issued two "red alerts" on heavy air pollution since the start of this winter, prompting closures of schools and bans on outdoor construction, while another round of smog has been predicted to hit the city later this week.
The Ministry of Environmental Protection has said coal burning is the primary source of air pollution in north China during the winter heating season, followed by car exhaust, industrial emissions and construction-site dust.
Experts said this winter's smog was also aided by a strong El Nino effect, which brought static weather patterns that made it difficult for air-borne pollutants to disperse.
According to the Beijing Municipal Environmental Monitoring Center (BMEMC), the city recorded 22 days of severe air pollution in November and December, 15 days more than the same period in 2014. During the period, average PM 2.5 density hit 239 micrograms per cubic meter.
Air quality has seen general improvement over the past year though, with a year-on-year drop of 6.2 percent in the average PM2.5 reading, which measures fine particles that can penetrate deep into lungs and cause more harm to health.
