Brussels, Belgium – Europe's industry chief says she sees diesel engines disappearing from markets much faster than expected after the European Parliament on Tuesday endorsed tougher rules aimed at preventing a rerun of the Volkswagen emissions cheating scandal.
In response to Volkswagen's admission in September 2015 that it used software to cheat US diesel pollution controls - a scandal that spotlighted the EU's lax vehicle regulations - the European Commission proposed an overhaul of rules on how vehicles are licensed and tested.
Its lawmakers voted 585 to 77 in favour of the draft bill, which would bolster EU oversight and allow Brussels to fine car makers up to €30 000 (R440 000) per vehicle.
European Commissioner Elzbieta Bienkowska said the new measures would eventually take diesel cars off the roads.
"Diesel will not disappear from one day to another," she told EU lawmakers on Tuesday. "But after this year of work, I am quite sure they will disappear much faster than we can imagine."
Under the draft law, car companies would no longer pay the testing agency directly. In a bid to break this cosy relationship, EU nations would have to fund car exhaust testing centres, although they would be allowed to levy fees from car makers to do so.
Brussels would get powers to carry out vehicle spot-checks and levy fines, while national authorities would be able to peer-review each other's decisions.
The bill calls for fines levied by EU regulators to be used to compensate car owners and boost environmental protection or market surveillance measures.
The law still needs to be finalised in negotiations between EU lawmakers, the Commission and member states.
The proposed rules, however, stop short of creating an independent market surveillance agency such as the US Environment Protection Agency – one of the key recommendations of a parliamentary report into the Dieselgate scandal.
Environment groups called it a missed opportunity, saying the scandal had clearly shown the need for stronger oversight.
The non-binding report adopted in a plenary on Tuesday also accused EU legislators and governments of caving in to lobbying efforts and being too slow to adopt reforms.
Following the VW scandal, national investigations revealed on-road nitrogen oxide emissions as high as 15 times the regulatory limits, as well as the use of devices to reduce exhaust treatment.
The use of such devices is illegal under EU law, but car manufacturers have invoked an EU legal loophole that allows them to use software to scale back emissions controls when necessary to protect car engines. All deny breaking the law.
