Editing Vehicle emissions control (section)

===Europe===
The [[European Union]] has control over regulation of emissions in EU member states; however, many member states have their own government bodies to enforce and implement these regulations in their respective countries. In short, the EU forms the policy (by setting limits such as the [[European emission standard]]) and the member states decide how to best implement it in their own country.

====United Kingdom====
In the United Kingdom, matters concerning environmental policy are "devolved powers" so that some of the constituent countries deal with it separately through their own government bodies set up to deal with environmental issues:
* [[Environment Agency]] – England and Wales
* [[Scottish Environment Protection Agency]] (SEPA) – Scotland
* [[Department of the Environment (Northern Ireland)|Department of the Environment]] – Northern Ireland

However, many UK-wide policies are handled by the [[Department for Environment, Food and Rural Affairs]] (DEFRA) and they are still subject to EU regulations.
