The better the environment, the less obvious the pollution reduction effect? Shanghai's "Half Year Report" provides answers nationwide | concentration | Shanghai
For five consecutive years of decline, the annual average concentration of fine particulate matter in Shanghai dropped to 25 micrograms per cubic meter in 2022, the lowest value since monitoring records began.
The ecological environment quality is getting better and better, and people living in Shanghai are becoming happier. However, environmental governance conforms to the law of diminishing marginal benefits. In the past, as the governance efforts increase, the effect of pollution reduction is very obvious. However, as the governance efforts increase, the effect may not be significant.
Can Shanghai break this pattern? Today is the first National Ecological Day, and the latest semi annual report on Shanghai's ecological environment provides a phased answer: in the first half of this year, the average concentration of fine particulate matter in Shanghai was 30 micrograms/cubic meter, and the excellent rate of environmental air quality index was 87.8%, an increase of 0.5% year-on-year; 92.3% of the 273 surface water assessment sections in the city are classified as excellent Class III, and Class V and inferior Class V sections have been eliminated.
The livable environment not only attracts people, but also makes Shanghai favored by many birds and fish. As of May this year, Shanghai has recorded 519 species of birds belonging to 251 genera and 80 families in 22 orders, accounting for 34.6% of the total bird species in China. Wild birds account for 84% of the total wild animal species in Shanghai. A large number of economic fish such as eel, dark striped pufferfish, and coilia, as well as Chinese mitten crab, inhabit Shanghai, which is also a passage for rare and endangered animals such as Yangtze River finless porpoise and Chinese sturgeon to write their life history. The latest data shows that Shanghai has monitored and recorded 150 species of nationally protected wildlife, over 325 species of terrestrial wildlife with important ecological, scientific, and social value, and 46 species of locally protected wildlife.

The significant environmental governance effect is still ongoing, and the decisive factor is the persistent battle against pollution prevention and control.
In terms of defending the blue sky, Shanghai has issued the Clean Air Action Plan and two special action plans to continuously promote the special rectification of volatile organic compounds. Starting from April 1st this year, the city wide restriction of National III diesel trucks will be implemented.
In terms of the defense of clear waters, Shanghai is promoting the construction of ecological clean small watershed demonstration sites, accelerating the fourth phase of the Suzhou River environmental comprehensive improvement project, and carrying out marine ecological environment governance in Jinshan District.
In terms of the clean land defense war, Shanghai has introduced soil pollution prevention and control regulations and a "waste free city" construction plan, accelerating the construction of a batch of wet waste disposal facilities such as the third phase of bioenergy reuse in Laogang. In addition, we will steadily advance the central ecological environment protection inspection and the rectification of the Yangtze River warning film, and carry out routine inspections at the city level in Changning District and Qingpu District.
While making every effort to control pollution, Shanghai adheres to the bottom line of the ecological environment. Firstly, it focuses on important sensitive areas such as the Chongming East Beach to carry out wetland ecological restoration projects, and implements pilot projects for the treatment of Jiuduan Sand, Spartina alterniflora, and Rice Grass; The second is to continuously optimize the ecological spatial pattern. Last year, 81 greenways with a total length of 231.88 kilometers were built, bringing the total length of greenways in Shanghai to 1537.78 kilometers. With the construction of 1055 hectares of new green space and 51000 acres of newly added forests landing last year, as of the end of 2022, Shanghai has included 670 types of parks in the management of urban and rural parks, with a forest area of 1.898 million acres and a forest coverage rate of 18.51%. The third is to strengthen the safe utilization of contaminated farmland, strengthen environmental risk prevention and control in key areas such as drinking water sources, hazardous waste, nuclear and radiation, and regularly carry out cross regional and cross departmental joint law enforcement.
The comprehensive green transformation of production and life is the perpetual motivation for promoting high-quality development.
In the field of energy, Shanghai has implemented energy-saving and carbon reduction transformation of coal-fired power, and promoted major projects such as offshore wind power demonstration. In the industrial field, we must resolutely curb the blind development of "two high" projects and promote industrial structure adjustment. In the field of transportation, accelerate the formation of a green and low-carbon transportation structure, and solidly promote the development of multimodal transportation such as sea rail intermodal transportation and river sea intermodal transportation. In the field of architecture, we will promote the construction of ultra-low energy buildings and the energy-saving renovation of existing public buildings.

The issue of ecological environment is not a matter of sweeping snow in front of each door, but rather a matter of "everyone prospers and everyone suffers".
Shanghai actively plays a leading role in promoting ecological environment protection and joint governance in the Yangtze River Delta region. Up to now, the "three unifications" system of ecological environment standards, monitoring and law enforcement has been promoted in key areas such as Hangzhou Bay and around the Taihu Lake Lake. Ecological environment information such as air and water and high pollution vehicle information have been shared in the region. In addition, the Yangtze River Delta region has formulated a special plan for the ecological environment of the Yangtze River Delta Ecological Green Integration Development Demonstration Zone, and is also promoting collaborative legislation for the protection of drinking water sources in the integrated demonstration zone and the establishment of the Taipu River ecological compensation mechanism.
