European standards for transportation aim at the production of cleaner transport vehicles. These standards have become increasingly stringent. A new set of standards will be introduced in September 2014: Euro6. Euro6 will require all fleet owners to equip their trucks with a SCR-system witháAdBlue injection. Mandatory emission standards for transportation will become increasingly demanding in the future. Several non-European countries are adopting standards and others are likely to follow (e.g. Brazil in 2012). Transport vehicles have to be cleaner and emit less harmful exhaust gasses like NOx and CO2. European emission legislation is summarized below. For original documents please visit EUR-lex (European).
Euro6 will come into force in September of 2014. It will especially affect standards for diesel driven vehicles, requiring further reduction of NOx and Hydrocarbon emission. Consequently, the SCR system and AdBlue will become vital to meeting the Euro6 standards.
Euro5 was introduced in the EU in 2009. It proposes to limit harmful emission from Heavy Goods Vehicles (HGVs). Most commercial vehicle manufacturers resorted to the Selective Catalyst Reduction system (SCR)
Euro4 was introduced in the EU in 2005. It proposed further limiting of petrol and diesel vehicles emissions.
Euro3 was introduced in the EU in 1999. It limited diesel car emissions. Euro3 also included legislation for Heavy Goods Vehicles.
Euro1 came into force in 1993, setting emission standards for commercial vehicles and light trucks. It was the start of a step by step reduction of emissions from all engines to improve air quality in Europe. Euro1 was soon followed by Euro2 in 1996, which included legislation for motorcycles.
