China is experience in the blue sky Defense War: atmosphere control and accelerating coordinatio

　　On December 3, the fourth "blue making" international clean air conference was held in Beijing. Together, the twenty fourth session of the conference of the parties to the United Nations climate change structure Treaty (cop24) is also being held in Poland.

　　As one of the parties to the Paris Agreement, China has made great progress in greenhouse gas emission reduction in the past few years. By 2017, the carbon emission intensity per unit of GDP in China has decreased by 46% compared with that in 2005, and the carbon emission intensity per unit of GDP in 2020 has been completed ahead of schedule

　　Commitment to reduce emission intensity by 40% ~ 45%.

　　Jiang Kejun, a researcher at the Institute of Power Research of the national development and Reform Commission, said at the fourth international clean air conference: "China is implementing the Paris Agreement in accordance with the established road, and we have a certain possibility to complete zero emissions by 2050, so as to achieve a win-win situation of air quality improvement and greenhouse gas emission reduction. The development of industry and skills will play a decisive role in the end of this policy Role. "

　　In fact, greenhouse gases and air pollutants have the same root identity. The biggest reason for air pollution and global warming is the burning of fossil fuels. The policies, methods and skills of air pollution prevention and control will eventually point to the clean power structure, industrial structure, transportation mode and construction energy. These operations will bring huge greenhouse gas emission reduction effects and be useful to cope with global climate change.

　　In the past five years, China has launched the most intensive, comprehensive and meticulous air pollution prevention and control activities ever.

　　At the fourth international clean air conference of "Chuangyang blue", the Chuangyang Clean Air Alliance released "Chen Shuo (2018) of China's ambient air quality management evaluation". Chen said that he not only systematically recalled the progress made in air quality, pollutant emission reduction, policy release and air quality management during the implementation of the "air pollution prevention and control action plan" (hereinafter referred to as "air 10"), but also made a further analysis on the progress of air pollution prevention and control in response to climate change.

　　According to Chen Shuo, since the implementation of the "air ten" in 2013, it has effectively promoted the coordinated response to climate change. The growth rate of carbon emissions in China is basically zero, and the reduction of unit GDP emission intensity in 2020 has been completed ahead of time 40% - 45% commitment.

　　In China, the proportion of coal in total power consumption has continued to decline for five consecutive years, and the initial negative growth of total coal consumption in China since nearly 16 years. Most provinces and cities have set up the total coal consumption control policies and completed the negative growth of the total coal consumption. Among them, seven provinces (cities) that put forward the requirements of the negative growth of the coal consumption in the "atmosphere 10" have completed the policies.

　　Chen said he also made a benchmarking analysis on the completion of the 13th five year plan for greenhouse gas emission control and air quality. A number of audit policies proposed in the 13th five year plan for greenhouse gas emission control, such as total power consumption, power consumption per unit of GDP and total coal consumption, have been completed in advance. PM2.5 annual average concentration, ratio of heavy and above pollution days, SO2

　　And NOx emissions are also expected to accelerate the completion of 2020 policy.

　　In addition, Chen said, he also analyzed China's air quality change in 2013-2017. In 2017, the Ministry of environmental protection signed the letter of responsibility for air pollution prevention and control policy with all provinces (districts / cities) in China

　　PM2.5

　　In order to check all regions of the policy, the reduction policy has been completed, and the annual average SO2 concentration of each province (district / city) is also initially lower than the national secondary standard. However, at that time, the atmospheric environment situation is still severe, and the weather conditions in winter 2018 are generally more wrong than that in 2017. In the future, China's air quality improvement is still arduous, and the challenges will continue to upgrade.

　　At the fourth international clean air conference of "creating blue", the avenue climate change promotion center and the clean air alliance jointly launched the "Yan'an clean heating pilot project skills Collection activity" to jointly cope with climate change while improving air quality.

　　Yang peidan, director of the avenue climate change promotion center, said at the meeting that clean heating can reduce the black carbon emissions caused by the burning of civil bulk coal. Promoting clean heating is a skill road with obvious synergistic effect.

　　"Taking air pollution prevention and control as the starting point, maximizing the benefits of coordinated response to climate change will become a very useful way to cope with climate change, which has great international promotion value and deserves more attention," said Xie Hongxing, director of Chuanglan clean air alliance, at the meeting.
