EU car emissions: Tough new tests backed:
New car models sold after September 2017 will not be allowed to exceed nitrogen oxide emission levels by more than twice the technical limit.

Car makers will have until 2019 to limit the emissions on all new vehicles to that level.

By 2020, the emissions from all new models must not be greater than 1.5 times the technical limit. The same rule will apply to all new vehicle from 2021.

"The EU is the first and only region in the world to mandate these robust testing methods," EU Commissioner Elzbieta Bienkowska said.
