Emissions regulations are legal requirements governing the amount of pollutants that can be released into the environment. These regulations are designed to protect public health and the environment by limiting the emission of harmful substances such as carbon monoxide, nitrogen oxides, sulfur oxides, and particulate matter. The development and enforcement of these regulations are typically overseen by governmental agencies like the Environmental Protection Agency (EPA) in the United States and the European Environment Agency (EEA) in Europe.
