How effective has China's ecological civilization and beautiful China achieved since the 13th five year plan? What does the green winter Olympics bring us? Wang Jinnan, academician of the Chinese Academy of engineering, President of the Environmental Planning Institute of the Ministry of ecology and environment and President of the Chinese society of Environmental Sciences, introduced at the special press conference of the beautiful China Green Winter Olympics held on the 18th that in the past five years, China has become the world's largest country in the use of new and renewable energy. The blue sky, white clouds and twinkling stars have become the norm, and the scenes of clear water, green shore and fish flying at the bottom have increased significantly. According to the data observed by NASA, about 25% of the new green area in the world since 2000 comes from China.

China's ecological environment protection has achieved a historic, turning and comprehensive leap forward

Since 1972, the Chinese government started the cause of environmental protection, this year is exactly 50 years of China's ecological and environmental protection. Wang Jinnan introduced that China's ecological and environmental protection has gone from the early treatment of "three wastes", to the treatment of key polluting cities, to "three rivers, three lakes, two districts, one city and one sea", to the reduction of total pollutants, to the improvement of environmental quality, to the three action plans and the battle for pollution prevention and control, and to the goal of basically realizing a beautiful China by 2035 proposed by the 19th CPC National Congress in 2017, Especially in the five years since the 13th five year plan, China's ecological environment protection has achieved a historic, turning and comprehensive leap forward. China's ecological and environmental protection is entering a critical period focusing on carbon reduction, promoting the synergy of pollution and carbon reduction, promoting the comprehensive green transformation of economic and social development, and realizing the improvement of ecological and environmental quality from quantitative change to qualitative change. It has comprehensively opened a new journey of building a modern, blue sky, clear water, pure land and beautiful China with harmonious coexistence between man and nature.

In the past five years, the construction of a beautiful China has made phased progress. Over the past five years, the results of green development have gradually emerged. The proportion of coal consumption in energy consumption has decreased to about 56%, and the proportion of clean energy has increased to 25.3%. The installed capacity and power generation of photovoltaic and wind energy, and the production and sales of new energy vehicles rank first in the world. Among them, the sales of new energy vehicles in 2021 increased by 1.6 times year-on-year, accounting for more than half of the world sales, Become the world's largest country in the use of new and renewable energy. In 2020, China's carbon dioxide emissions per unit of GDP decreased by 18.8% compared with 2015 and 48.4% compared with 2005, exceeding the 40% - 45% target promised to the international community. It is also one of the countries with the fastest reduction in energy consumption intensity in the world, basically reversing the rapid growth of carbon dioxide emissions.

Over the past five years, the quality of China's ecological environment has continued to improve. From 2017 to 2021, the concentration of fine particles in cities at prefecture level and above decreased by 25%, the proportion of excellent days increased by 4.9%, the number of days with heavy pollution decreased by nearly 40%, and the twinkling of blue sky, white clouds and stars has become the norm. The proportion of water bodies reaching or better than Class III increased to 84.9%, the proportion of water bodies inferior to class V decreased to 1.2%, and the scenes of clear water, green shore and fish flying shallow bottom increased significantly. The level of safe utilization of soil has been steadily improved, the red line of ecological protection has been preliminarily defined, and large-scale land greening operations have been carried out continuously. The forest coverage rate has reached 23.04%. According to the data observed by NASA, about 25% of the new green area in the world since 2000 comes from China. The overall stability of ecosystem pattern and biodiversity protection has retained more birds and flowers for the people Rural scenery. People's happiness and recognition of blue sky and clear water have increased significantly, creating the successful practice of the largest developing country in effectively protecting the environment while rapid economic and social development.

Over the past five years, the capacity of modern ecological environment management has been continuously improved. The system of main functional areas has been gradually improved, the central ecological and environmental protection inspector has developed in depth, the environmental governance systems such as pollutant discharge permit, ecological compensation and prohibition of foreign garbage have been accelerated, and the "four beams and eight pillars" system of ecological civilization has been basically formed. At the same time, actively participate in global environment and Climate Governance, make a solemn commitment to achieve carbon peak by 2030 and carbon neutralization by 2060, and integrate "double carbon" into the overall layout of ecological civilization construction and high-quality development.

Over the past five years, Green Olympics has changed from vision to reality from concept to action. The Chinese government has fully implemented the Green Olympics initiative, made full use of the original Olympic venues such as the bird's nest, water cube and Wukesong, and added venues to reduce the impact on the environment from the design source. The "ice ribbon" of the national speed skating hall has become the world's First Avenue speed skating hall that uses carbon dioxide transcritical direct cooling system to make ice, with carbon emissions approaching zero; All venues of the Winter Olympic Games meet the green building standards and 100% of conventional energy uses green electricity. Energy saving and clean energy vehicles account for 84.9% of all games time guaranteed vehicles, the highest in previous winter Olympics. At the opening ceremony, "no ignition" replaced "ignition" and "low fire" replaced the raging fire, fully reflecting low-carbon and environmental protection. It can be said that this is a new starting point of the Green Olympics. Through the use of a large number of photovoltaic and wind power generation, local donation of forestry carbon sink and enterprise sponsorship to certify carbon emission reduction, the Beijing Winter Olympic Games has successfully fulfilled its commitment to achieve carbon neutrality. The Beijing Winter Olympic Games has become the first "carbon neutral" Winter Olympic Games so far. Reports from relevant media and authoritative magazines also confirmed this. China held a "green" Winter Olympic Games, demonstrating its leading position in the field of green technology. The Nature magazine pointed out that the emission reduction measures taken by the Beijing Winter Olympics are much higher than those of the previous winter Olympics. Although the carbon emission reduction of the Winter Olympics is only a drop in the total carbon emission of China, it proves that it is feasible to achieve carbon neutrality in a wider range of activities.

Over the past five years, Beijing, as the city of the two Olympic Games, has created a world miracle in air pollution control in mega cities in terms of air quality improvement. Since the 2008 Beijing Olympic Games, we have made unremitting efforts to control air pollution in Beijing and Beijing Tianjin Hebei region. Improving the quality of Beijing's ecological environment, especially the air quality during the competition period, is also a solemn commitment made by China in its bid for the Winter Olympics. Through the fight against pollution, a series of major measures have been taken to protect and control the ecological environment. Beijing's air quality has improved significantly. In 2021, all six major pollutants in Beijing reached the standard for the first time, and the concentration of fine particles decreased to 33 μ g / m3, a decrease of 40% compared with 2017. The number of excellent days reached 288, an increase of 62 days compared with 2017. Beijing Blue has increasingly become the norm, Especially during the Winter Olympics, the air quality in Beijing reached PM2 5. The best level since monitoring, PM2 in a few days The concentration of 5 even appears in single digits. The experience of the United Nations Environmental Protection Agency in dealing with atmospheric pollution in Beijing has provided a high evaluation of the effectiveness of air pollution control in developing cities. More than 20 kilometers to the west, it used to be the famous Shougang. In order to improve the air quality in Beijing, it has been relocated as a whole. At present, it has been built into the office of the Beijing Winter Olympics Organizing Committee and the big platform competition venue for freestyle skiing, realizing the gorgeous transformation from "steel-making fire" to "snow dance and ice flying". This is a green Olympic Games A vivid practice and a beautiful landscape of beautiful China.

Wang Jinnan stressed that just like the spirit of the Beijing Winter Olympics as interpreted by the theme slogan of the Winter Olympics "towards the future together", China will take the green winter Olympics as an opportunity, follow the strategic deployment of ecological civilization and the construction of a beautiful China, focus on key points, make up for weaknesses and strengths, deepen the battle against pollution prevention and control, and accelerate the comprehensive green transformation of economic and social development, We will solidly promote carbon peak and carbon neutralization, continuously improve the quality of the ecological environment, promote the construction of ecological civilization and a beautiful China to a new level, and make new and greater contributions to the construction of a community with a shared future for mankind and a beautiful home on earth.
