Exhaust emissions

European rules affecting exhaust emissions from cars first came into force in 1970 and have been tightened up progressively ever since.

The limits form part of the European type approval regulations – a collection of safety and environmental tests which a new vehicle must pass before it can be sold in the European Union.

The latest Euro standards, Euro 4 (January 2005) and Euro 5 (September 2009) and Euro 6 (September 2014) concentrated on cleaning up emissions from diesel cars, especially particulate matter(PM) and oxides of nitrogen (NOx). Diesel cars needed particulate filters to meet Euro 5 standards.

Euro 6, applies to new type approvals from September 2014 and all new cars from September 2015 and reduces some pollutants by 96% compared to the 1992 limits.
