In the Netherlands, the focus is on reducing nitrogen emissions through stricter standards for agriculture and industry, especially after the invalidation of the Nitrogen Action Programme (PAS).

The European Union has directives such as the Habitat Directive and the Nitrates Directive, which require member states to control nitrogen emissions to protect natural areas.

In North America, the United States and Canada are leading examples with regulations such as the Clean Air Act, which sets strict standards for NO_X emissions from industrial and mobile sources.
