blue badge – Stuttgart 2018

On the current occasion, I would start the debate…I leased my Dicken T5 until 2019 and was already pinched as a field serviceman if I could not drive into the inner cities (since currently Euro 5) Since I am thinking about changing to a T6 (and here actually wanted the Euro 6 diesel) I had thought about a change to the TSI this morning. However, the press reports that the Stuttgart example is not about fine dust, but about the Co2 and, according to the r Homepage of VW more Co2 than the diesel out of the TSI (173g/km to 212g/km) Is it therefore a fallacy to assume that if necessary the government will keep a blue badge on the Euro standard of the engine? What if the blue badge on the Co2 emissions is awarded? If so, does a diesel not get the badge of the petrol engine?
