Beijing Academy of Central Branch： PM2.5 concentrations expected in 2030 targets

Legal evening news (reporters Bai Bing) in accordance with the new national air quality standards for PM2.5 annual average only standard to 35 micrograms per cubic meter. Beijing in 2013, annual average PM2.5 concentrations for 89.5 mg/m, 1.56 times times higher than national standard. Even by the clean air action plan calls in 2017 to reach 60 micrograms/cubic meter may also be exceeded. So when can we reach them?

2014 to be held in the morning at the Beijing International Symposium on the urban environment, Pan Tao, Dean of the Beijing Central section gave the answer, "2030 PM2.5 concentrations are expected to reach".

Pan Tao were presented at the seminar on governance status and prospect of air pollution in Beijing. At present, the air pollutant sulfur dioxide levels than in 1998, a decline of 77%, has standard, concentrations of nitrogen dioxide down 30%,PM10 down 42%.

Last year, the city made for PM2.5 monitoring. Through research, PM2.5 concentrations in the winter months (December to February) average peaked at 87.14 micrograms/cubic meter, in spring (March to May) minimum, 68.67 micrograms/cubic meter. In addition, summer (June to August) 79.96 concentration mg/m; in autumn (September to November) concentration of 81.13 μg/m3.

Pollution in Beijing how to deal? Pan Tao believes that current pollutant emissions still far exceeds capacity, once the adverse weather conditions, heavy pollution that must inevitably come. Pollutant emission reduction is the first task of improving the atmospheric environmental quality.

However, Pan Tao said, the Beijing urban planning over-expansion, high intensity, rapid population growth, urban planning under reasonable, it has become important to improve the quality of the environment constraints. Beijing has narrowed in the emission reduction potential and increased difficulty. If it cannot be made from the plan to adjust and reconcile the population, then emission reduction capabilities are limited.

Therefore, management needs from various aspects of air pollution in Beijing a multi-pronged, can't just grab one. "If a motor vehicle is not on the road, heavy pollution will still occur, but cannot because it does not control vehicle, any major sources of pollution will have an impact on air quality in Beijing. "Pan Tao said.

In addition, at present, the ongoing preparation of the Central Branch of the Beijing environment master plan (2015-2030) and the planning of Beijing's air quality standards. Among them, the Beijing environmental master plan will be completed next year. The planned environmental quality standards by 2030 as the goal, from the perspective of resources and environmental constraints, determine the appropriate size, structure and layout of urban development. Determining the planning period strategic direction and implementation of urban and rural environmental protection paths and key measures.

Planning clear environmental carrying capacity of resources and ecological lines, environmental zoning, regional environmental strategies, based on environmental quality improvement of industrial and urban spatial layout, pattern for ecological security and other key issues. In addition, Pan Tao, Central Academy of Beijing, PM2.5 was measured to be in 2030 to meet national standards of 35 μg/m3, and measures assessed to measure year by year. If the measures are effective, Pan Tao believes that 2030 PM2.5 standards were promising.
