97% percent of all modern-day diesel vehicles give off more poisonous nitrogen oxide (NOx) contamination on the road than the official limit, as per the most detailed set of data yet released, with a quarter producing a minimum of six times more than the limit.
Remarkably, the small number of designs that did not surpass the requirement were mainly Volkswagens, the carmaker whose cheating of diesel emissions tests which emerged in 2015 sparked the scandal. Professionals said the brand-new results reveal that clean diesel automobiles can be made however that essentially all producers have failed to do so.
The brand-new data, from screening industry leader Emissions Analytics (EA), follows the publication by the Department for Transportation of emissions results for 37 automobiles, all of which discharged more NOx on the road than the main limitation. The new information covers more than 250 vehicles in more rigorously standardised road conditions. EA discovered that just among 201 Euro 5 diesels, the EU requirement from 2009, did not go beyond the limit, while only seven of 62 Euro 6 diesels, the stricter requirement since 2014, did so.
Diesel vehicles have to satisfy an official EU limit for NOx but are only tested in a laboratory under fixed conditions. All automobiles sold pass this policy however, when taken out on to real roadways, almost all emit far more contamination. There is no idea that any of the vehicles tested broke the law on emissions limitations or used any cheat gadgets.
Mayoral candidates located in London, the city with the worst air quality in Britain, have seized on the DfT data to call for tighter controls on contaminating traffic– including a restriction on diesel cars.
