With the acceleration of society, industrialization and urbanization, air quality problems have become increasingly prominent, which has become one of the important factors restricting the sustainable development of economy and society. Faced with this challenge, countries have introduced a series of policies and measures to improve air quality, among which environmental protection, as a core component, plays a vital role in air control strategies.

1. Source control: reduce pollution emissions.

Source control is the most direct and effective way to prevent and control air pollution. By promoting the use of clean energy (such as natural gas instead of coal), improving energy efficiency standards, and implementing stricter restrictions on vehicle exhaust emissions, the amount of pollutants generated will be reduced from the root. In addition, advanced technology and equipment are adopted to deal with the waste gas emission in the industrial production process to ensure that it meets the national or local emission standards.

2. Environmental supervision: strengthen law enforcement.

Establish and improve the environmental monitoring system, strengthen the monitoring of air quality in key industries and regions, and find and solve existing problems in time. At the same time, strengthen the investigation and punishment of illegal sewage discharge, strictly enforce relevant laws and regulations, punish those who violate the regulations according to law, form a powerful deterrent, and urge enterprises to consciously abide by environmental protection requirements.

3. Public participation: enhancing environmental awareness

The government should actively guide all sectors of society to pay attention to and support atmospheric protection work, popularize scientific knowledge through various media platforms, and enhance citizens' sense of environmental responsibility and action. Encourage the public to participate in the specific practice of energy conservation and emission reduction in daily life, such as choosing public transport and reducing the use of disposable plastic products. Through collective efforts, we will jointly create a good ecological environment.

4. Scientific and technological innovation: promoting green transformation

Scientific and technological innovation is the key driving force to achieve the goal of air pollution control. Support the research and development of more efficient and clean technical solutions and accelerate the development of new energy vehicles, smart grids and other fields; Promote the construction of circular economy model, optimize the resource allocation structure, reduce the energy consumption level per unit GDP, and fundamentally change the traditional development model of high energy consumption and high pollution.

In a word, air treatment is a systematic project, which requires the joint efforts of the government, enterprises and every ordinary citizen. Only by organically combining the above measures can we effectively promote the continuous improvement of air quality in China and even around the world and leave a beautiful home with blue sky and white clouds for future generations.
