In wake of VW scandal

Opus Inspection has compiled and analyzed on-road emissions data indicating that emissions violations of vehicles under real-world driving conditions may well go far beyond VW diesels.

– A two-pronged approach that continuously monitors real-world emissions is the only effective remedy, Lothar Geilen, CEO of Opus Inspection says.

In the U.S., the EPA says it will add on-road testing to its regimen; German Environment Minister Barbara Hendricks says regulations have to be demanding enough that diesel vehicles truly cause less pollution, with independent authorities' conducting controls to verify it; and U.K. Transport Secretary Patrick McLoughlin says the U.K. leads Europe in calling for real-world testing.
