Dirty diesel cars ply EU roads

Down to Earth - - THE FORTNIGHT -

EUROPE, KNOWN for its tight emis­sion norms, has 29 mil­lion highly pol­lut­ing mod­ern diesel ve­hi­cles ply­ing its roads. This is about 76 per cent of the diesel ve­hi­cles regis­tered be­tween 2009 and 2015, says a study by Euro­pean ad­vo­cacy group, Trans­port and En­vi­ron­ment (T&E). Over four in five cars that meet the Euro-V stan­dard for ni­tro­gen ox­ides (NOx) in the lab­o­ra­tory pro­duce over three times the 180 g per 1,000 km limit when driven on the road. Two-thirds of the Euro-VI cars, mostly on sale since 2015, also pro­duce over three times the 80 g per 1,000 km limit in real world con­di­tion. About 70 per cent of these dirty diesel ve­hi­cles are sold in France, Ger­many, Italy and the UK. These cars switch off their ex­haust af­ter-treat­ment sys­tem to im­prove fuel econ­omy. These cars could be re­spon­si­ble for the high NOx lev­els in cities that lead to the pre­ma­ture death of 72,000 EU cit­i­zens an­nu­ally, says T&E.
