diesel cars emissions are actually an order of magnitude higher than most current standards, so if they remain within Euro 6 boundaries that would be great news. Apparently that is the case now for new cars in the market since Sep/2015. Unfortunately many (most?) diesel cars being sold today still emit far in excess of the Euro 6 specification in real-world conditions. The EQUA air quality index assigns ratings (A to H) to vehicles based on how they perform in real world conditions. The number of diesel models that are getting G or H grades (indicating they emit at least 12X more NOx than the Euro 6 specification allows) is quite alarming: http://equaindex.com/equa-air-quality-index/ http://equaindex.com/equa-air-quality-index/
