I find myself wondering if Renault’s decision to withdraw diesel engines is being driven by the environment, or by difficulty in getting these engines through RDE2? I guess it’s a combination of both, does anyone know?

The resulting impact on the environment, I think, is a mixed bag; good news for local emissions probably (although RDE2 compliant means much cleaner than older diesels) but for CO2 it’s probably bad news. I’m guessing a lot of buyers will now buy non-hybrid petrol and that means a lot more tail-pipe CO2 now and for the whole life of the car, which will typically be more than 10 years.

Isn’t it funny how some CO2 emissions are really important, and others seem to be just fine?
