Legislation plays a critical role in addressing air pollution by establishing standards and regulations that limit emissions from various sources. Laws such as the Clean Air Act in the United States set national air quality standards and empower regulatory agencies to enforce compliance. These regulations can lead to significant reductions in pollutants and improve air quality over time. Additionally, international agreements, such as the Paris Agreement, aim to unite countries in the fight against climate change and its associated air quality issues. Effective legislation not only holds industries accountable but also promotes sustainable practices and encourages innovation in pollution control technologies.
