European emission standards

The European emission standards are vehicle emission standards that regulate pollution from the use of new land vehicles sold in the European Union and European Economic Area member states and the United Kingdom, and ships in European territorial waters. These standards target air pollution from exhaust gases, brake dust, and tyre rubber pollution, and are defined through a series of European Union directives that progressively introduced stricter limits to reduce environmental impact.
