To comply with the German Energieverbrauchskennzeichnungsverordnung (EnVKV) DV has, next to the usual fields for emissions and consumption, also support for specific German fields. These for example include the CO₂ class and energy costs.
DV can check if a vehicle complies with the EnVKV regulations and prevent a listing for coming online if it doesn't. DV will also give feedback to the advertiser so the necessary information can be supplemented.
