On December 3, the fourth "blue creation" foreign clean atmosphere conference was held in Beijing. At the same time, the 24th Meeting of the United Nations climate change framework Conference (cop24) is also being held in Poland.
As one of the parties to the Paris Agreement, China has gained great hope in greenhouse gas emission reduction in the past few years. In this year, the carbon emission intensity of China's unit GDP has dropped 46% compared with 2005, and completed the unit GDP in 2020 ahead of schedule
The emission intensity is allowed to drop by 40% ~ 45%
Jiang Kejun, a researcher of the Power Research Institute of the national development and Reform Commission, revealed at the fourth "create blue" foreign clean atmosphere conference: "China is implementing the Paris Agreement exactly according to the established path. We have to achieve zero emissions by 2050, so as to achieve a win-win situation of atmosphere quality improvement and greenhouse gas emission reduction. The development of home ownership and technology will carry forward this goal with determination Purpose. "
In fact, greenhouse gases and atmosphere pollution have the same root identity. The biggest reason for atmosphere pollution and global warming is the burning of fossil fuels. The policies, mistakes and technologies of atmosphere pollution prevention and control ultimately point to power layout, household layout, transportation mode, and clean and clean energy consumption of equipment. These things bring huge greenhouse gas emission reduction effects, which can be used to respond to global weather changes.
In the past five years, China has launched the most serious air pollution prevention and control actions, which are the most powerful, the most general, the most careful and the most serious
At the fourth "blue creation" foreign clean atmosphere conference, the blue creation clean atmosphere alliance released the report on China's situation, atmosphere, quality management and evaluation (2018). The report not only systematically reviews the hopes of China in terms of atmosphere quality, pollution reduction, policy announcement and atmosphere quality management mode in the implementation era of "air pollution prevention action decision" (hereinafter referred to as "air 10"), but also profoundly explains the hopes of air pollution prevention and control in response to climate change.
The request of "mediation to optimize household layout; accelerate mediation power layout, increase clean power supply" and the detailed implementation of the missing report are clearly put forward in the "air ten". Since the implementation of the "air ten" in 2013, it has effectively promoted the coordinated response to weather changes. China's carbon emission growth base is zero, and the unit GDP emission intensity drop in 2020 has been completed in advance 40% to 45%.
China has completed five consecutive years of decline in the proportion of coal in total power consumption, and the first negative increase in total coal consumption in the world in nearly 16 years. Numerous provinces and cities have allocated the goal of mastering the total coal consumption and completed the negative increase of the total coal consumption. Among them, seven provinces (cities) that put forward the request of negative increase of the coal consumption in the "atmosphere 10" have completed the goal.
The report also made a benchmarking explanation for the control of greenhouse gas emissions and the completion of the 13th five year plan for climate quality. Many audit objectives proposed in the 13th five year plan for the control of greenhouse gas emissions, such as total power cost, unit GDP power cost and total coal cost, have been completed in advance. PM2.5 annual average concentration, ratio of days with severe pollution and above, SO2
And the total amount of NOx emissions will also hope to accelerate the completion of the 2020 target
In addition, the report also describes the change of atmosphere quality in China from 2013 to this year. In this year, the Ministry of environmental protection and all provinces (districts / cities) signed the "obligations of air pollution prevention and control" in which
PM2.5
For the first time, the annual average SO2 concentration of each province (district / city) is lower than the national level II scale. But at present, the atmosphere situation is still serious, and the image premise of winter 2018 is all wrong compared with this year. It is still difficult for China to improve the atmosphere quality in the coming days, and the tetany will be connected with promotion.
At the fourth "create blue" foreign clean atmosphere conference, the road response weather change excited the middle and clean atmosphere alliance cooperated with the alliance to propose "Yan'an clean heating pilot project technology collection behavior", which coordinated response to weather change while improving the atmosphere quality
Yang peidan, the middle director of the response to the weather change, revealed 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 technology with remarkable synergy effect
At the meeting, Xie Hongxing, director of create blue clean atmosphere alliance, revealed: "taking the prevention and control of atmosphere pollution as the starting point, maximizing the benefit of collaborative response to weather change will become the most useful mode of response to weather change, which has a great cost of implementation abroad and should receive more attention.".
