Legislation plays a critical role in addressing the issue of acid rain by establishing regulatory frameworks that limit the emissions of sulfur dioxide and nitrogen oxides. In many countries, laws such as the Clean Air Act in the United States have been instrumental in reducing air pollution through the implementation of cap-and-trade systems and emissions trading programs. These regulations encourage industries to adopt cleaner technologies and practices to meet compliance standards. Additionally, international agreements, such as the Gothenburg Protocol, aim to reduce transboundary air pollution, recognizing that acid rain is a global issue that requires cooperative efforts among nations. Effective legislation not only helps mitigate the causes of acid rain but also promotes public health and environmental protection.
