A 40 percent drop in PM2.5 by 2020 from the average level in 2013 has been targeted for the heavily polluted Beijing-Tianjin-Hebei cluster.

The reduction in airborne particulate matter that has a diameter of less than 2.5 microns-and can penetrate the lungs-has been set by China's top economic planning agency to improve air quality and protect the ecological environment in the three areas.

According to officials at the National Development and Reform Commission, the annual average reading of PM2.5 in the region will drop to 73 by 2017 and to 64 by 2020.

The average reading in the area last year was 93, according to media reports.

But since November, spells of smog have seen the reading rise to at least 500, compared with the safety level of 25 set by the World Health Organization, and 75 set by the Chinese government. The situation forced many cities in North China, including Beijing and Tianjin, to issue red alerts for pollution.

Zhao Penggao, a deputy director of the commission's Department of Resource Conservation and Environmental Protection, said daunting challenges remain to achieving the goals.

"Major Chinese academics and think tanks still hold different views about the source of the smog. Coal consumption, vehicles and construction dust are surely the major causes," he said.

Xie Hongxing, director of the Innovation Centre for Clean-air Solutions, an environmental think tank in Beijing, said joint control of atmospheric pollution is important.

"More concerted efforts among regions are needed. The neighboring provinces of Shandong and Henan have also contributed greatly to pollution in the region," he said.

The commission and the Ministry of Environmental Protection have jointly drawn up a blueprint for ecological and environmental protection for the Beijing-Tianjin-Hebei region to reduce air, water and soil pollution.

Meanwhile, during the three-day New Year's holiday, many cities in northern and central areas of China are forecast to have smog due to a lack of wind, the China Meteorological Administration said on Wednesday.

Some areas in the Beijing-Tianjin-Hebei cluster are expected to have severe smog, with air pollution reaching hazardous levels on New Year's Day, said Zhang Zuqiang, spokesman for the top national weather authority.

In some areas, fog will cut visibility to less than 200 meters, he said. The severe smog is forecast to last until Sunday, when strong winds are expected to disperse it.
