Enhanced Environmentally Friendly Vehicle
Enhanced Environmentally Friendly Vehicle (EEV) is a voluntary European emissions standard for buses and trucks . The requirements are specified in the EU Directive 1999/96 / EC under "Level C". Vehicles equipped with EEV engines exceed the emission quality of the Euro V standard , which became mandatory on October 1, 2009 for buses and trucks for all newly registered vehicles with a gross vehicle weight of 3.5 tonnes or more.
In 2005, the German Federal Environment Ministry promoted the procurement of vehicles with EEV engines with a project for “demanding environmental standards in inner-city and regional distribution transport”. Other funding programs with the aim of low-emission local public transport also contributed to the fact that EEV motors are used far more frequently in buses than in trucks. On January 1, 2014, 21% of the 77,000 buses registered in Germany complied with the EEV standard, but only 7% of the 529,000 trucks over 3.5 tons.
Since January 1, 2014, newly registered buses and trucks from 3.5 tons must meet the stricter Euro VI standard.
