The new Worldwide Harmonised Light Vehicle Test Procedure (WLTP), designed to improve cars CO2 emissions testing in laboratory, will not stop carmaker manipulation of test results and will not close the gap between official and real world figures a new report by Transport & Environment shows.

Provisional data for European new car carbon emissions in 2017 published today shows the small but expected rise in new car CO2 emissions of 0.4g/km is due to the strong growth in sales of crossover and SUV models – mainly diesel powered.

Since 2012 new car CO2 emissions have reduced by just 2% on the road compared to nearly 11% in fake laboratory tests.
