Social and environmental problems have increasingly become one of the focuses of global attention. Among them, air quality is one of the most concerned issues. With the acceleration of industrialization and urbanization, air pollution has become a major obstacle to the sustainable development of China's economy and society. In order to meet this challenge, a series of policies and regulations have been promulgated at the national level, and various measures have been taken to improve air quality, which has achieved remarkable results.

First, improve the public health level

Air pollution has not only caused great damage to the ecological environment, but also directly threatened human health. People exposed to high concentrations of pollutants for a long time are prone to health problems such as respiratory diseases and cardiovascular diseases. By implementing strict emission standards, promoting the use of clean energy and strengthening the pollution control of industrial sources, the contents of harmful substances such as PM2.5 and sulfur dioxide in the air have been effectively reduced, which has significantly reduced the incidence of respiratory diseases among residents and improved the quality of life and happiness of the people.

Second, promote the transformation and upgrading of the economic structure

Controlling air pollution is not only the demand of environmental protection, but also the necessary condition to promote high-quality economic development. On the one hand, the government has increased its support for new energy vehicles, green buildings and other fields, and encouraged enterprises to adopt advanced technologies and equipment to reduce exhaust emissions; On the other hand, it is to eliminate backward production capacity, optimize the layout of industrial structure and cultivate strategic emerging industrial clusters. These measures not only reduce environmental pollution, but also inject new vitality into economic development, achieving the goal of win-win economic and ecological benefits.

Third, enhance the international image and cooperation opportunities

In recent years, while actively fulfilling the commitments of the Paris Agreement, China has actively participated in global climate change negotiations and shared its successful experience and technological achievements with other countries. Deepen international cooperation and exchanges by carrying out cross-border river water quality monitoring projects and supporting forest restoration projects in Africa. This not only enhances China's right to speak in the global climate governance system, but also provides a practical case for realizing the principle of common but differentiated responsibilities and establishes a good image of a responsible big country.

In a word, air pollution control is a complex and arduous task, which requires the joint efforts of the whole society to achieve lasting victory. In the future, we will continue to adhere to the concept of "Lucid waters and lush mountains are invaluable assets", unswervingly take the road of green development, and make the blue sky and white clouds become the bright background of beautiful China.
