Countries around the world have created laws to control air pollution and protect the environment. These laws limit how much pollution factories, vehicles, and other sources can release into the air.
In the United States, the Clean Air Act sets limits on emissions and helps keep air quality within safe levels. In the European Union, similar rules make sure that member countries meet strict targets for reducing pollution.
China has also made air pollution control a priority, investing in technology and cleaner energy to fight smog in its cities. These laws are important because they help industries lower their emissions and avoid fines or legal issues.
By following air quality regulations, businesses contribute to global efforts to protect the environment and public health.
