Environmental regulation is a multidisciplinary field of academic inquiry and a concept describing the body of laws, policies, and instruments designed to govern human activities that impact the environment. It investigates the development, implementation, effectiveness, and consequences of rules and mechanisms employed by governmental and non-governmental actors to prevent or mitigate environmental degradation, conserve natural resources, and promote ecological sustainability. Key characteristics include its reliance on legal frameworks, economic incentives, and social norms to shape behavior, its complexity across scales of governance, and its significance in addressing pressing environmental challenges and pursuing sustainable development goals.
