AIR POLLUTION * UK / Norway - Report: Diesel cars emit up to four times more toxic pollution than a bus

* England - Failure to use available technology to cut dangerous nitrogen oxides in new cars is a ‘disgrace’


-- A modern diesel car pumps out more toxic pollution than a bus or heavy truck, according to new data, a situation described as a “disgrace” by one Member European Parliament (MEP)... The revelation shows that effective technology to cut nitrogen oxides (NOx) pollution exists, but that car manufacturers are not implementing it in realistic driving conditions... Diesel cars tested in Norway produced quadruple the NOx emissions of large buses and lorries in city driving conditions, according to a report from the Norwegian Centre for Transport Research. A separate study for Transport for London showed that a small car in the “supermini” class emitted several times more NOx than most HGVs and the same amount as a 40-tonne vehicle... The issue of NOx pollution, thought to kill 23,500 people a year in the UK alone, gained prominence when VW diesels were discovered to be cheating official US emissions tests. The scandal also led to revelations that the diesels of many car manufacturers produce far more NOx on the road than in EU lab tests, though not via illegal means... The Transport for London research compared nine diesel cars, ranging from the super-mini class up to SUV, against three HGVs and one LGV. The NOx emitted from the cars was similar to that from the heavier trucks though one car – the smallest diesel tested – produced more than double the 12-tonne lorry and the same as the 40-tonne vehicle... Emissions expert James Tate, from the University of Leeds, said the reasons car manufacturers were not implementing the NOx reduction technology on cars were convenience and cost...
