Air quality set to improve
2017-10-30, ZHENG JINRAN and CAO YIN

China will see fundamental improvements in its environmental quality by 2035, when the average PM2.5 concentration in the air across the country will meet the national standard, Li Ganjie, minister of environmental protection, said on Oct 23.

“We are conducting studies to clarify the details of the fundamental improvement, but I think, in the field of air quality, it means the national average PM2.5 level will be lowered to 35 micrograms per cubic meter,” Li said at a news conference on the sidelines of the 19th National Congress of the Communist Party of China.

PM2.5 refers to hazardous fine particulate matter in the air. The micrograms per cubic meter concentration is one of the major measures used to describe air quality.

In some major areas with severe air pollution, the average PM2.5 level will also be lowered, Li said.

The latest data from the Ministry of Environmental Protection show that 338 cities across the country saw average PM2.5 concentrations of 47 micrograms per cubic meter last year, 34.3 percent higher than the standard.

“It’s not easy to reach the targets,” Li said. In fact, air pollution worsened in some areas, he added.

The Beijing-Tianjin-Hebei region in North China, along with neighboring provinces, experienced severe air pollution in recent years, especially during autumn and winter. The ministry has introduced stronger measures to reduce the air pollution in those areas.

Stricter measures governing discharges have been introduced to reduce emissions. Some heavy industries, for example, such as steel and cement manufacturing, will suspend production, and vehicles with heavy exhaust emissions will be restricted, documents from the ministry indicated.

Total emissions reduced in the winter months are estimated at double or triple what was cut the previous winter to help governments reach their air pollution reduction targets, the documents showed. “We will try our best to win the fight against air pollution,” Li said.

Hebei province, in which at least six cities ranked among the top 10 cities with the worst air pollution, has promised to strengthen restrictions, said Gao Jianmin, head of the provincial environment department, on Oct 23.

For example, Hebei has restricted coal consumption in rural areas. “Over 1.8 million households will switch to use clean energy — electricity or natural gas — for heating,” he said. “It’s estimated to cut the consumption of 4.8 million metric tons of coal.

“At least 100,000 small and polluting companies have been ordered to pause their production or shut down altogether this year, which will cut emissions,” Gao said.

“Air pollution has been our top priority, and anyone violating the restrictions — in a company or government — will receive severe punishment.”
