The Blue Angel is the ecolabel of the federal government of Germany since 1978. The Blue Angel sets standards for environmentally friendly product design. The ecolabel exists for 40 years and is regarded as a reliable guide for a more sustainable consumption. Mercedes-Benz has now delivered the first “Bleu Angel” eCitaro's to the German city of Jena.

The environmental label "Blue Angel" is awarded by independent institutions. The eCitaro is the first fully-electric city bus entitled to bear this environmental label. Jenaer Nahverkehr GmbH is the first transport operator to receive three eCitaro vehicles with the "Blue Angel". The company operates local public transport in the Thuringian university city, with a fleet including 43 city buses on 13 routes.

There are high hurdles to be taken before the environmental label "Blue Angel" can be awarded. For example, all-electric buses have to demonstrate a minimum capacity for their high-voltage batteries. Further prerequisites include a guarantee of at least five years or mileage of 200,000 kilometres on the batteries, the opportunity to return them at a later date, non-destructive battery change and the availability of replacement components for up to ten years after production has ended. In addition to this, the proportion of heavy metals in batteries is strictly limited. The requirements also cover the overall vehicle's environmental criteria. In paints and coatings, for instance, no lead, chromium oxide or cadmium compounds are permitted. As of the start of this year, only natural refrigerants are permitted for air conditioning systems.

The environmental label is carried by four renowned and independent institutions. The owner of the mark is the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. The German Environment Agency develops the technical and award criteria. The decision-making body is the Environmental Label Jury with representatives from numerous public institutions. The non-profit company RAL GmbH issues the "Blue Angel" environmental seal.
