Regulation of air quality has a federal and state law. On the federal level there is the Clean Air Act which regulates emissions of various sources including factories, power plants and vehicles. The Environmental Protection Agency sets criteria for determining the maximum pollutant level in different areas of the United States.
California, at state level has passed the California Clean Air Act. This law aims to lower greenhouse gas emission levels to protect public health as well as to prevent climate changes. The California Clean Air Act includes provisions to reduce smog forming pollutants and improve vehicle efficiency. This act also offers businesses incentives to invest in cleaner energy technologies, and sets targets for renewable energy production.
Having laws both at the state and federal levels allows organizations to make sure that all regulations are enforced in society. They can also ensure greater accountability, helping secure a brighter future for our planet.
