New 'real world' diesel tests fail to prevent rush hour pollution peak
New “real world” emissions tests fail to prevent high levels of pollution from diesel cars during rush hour, according to new data.
Diesel vehicles are the main cause of the UK’s widespread levels of illegal air pollution, with the VW cheating scandal exposing the fact that virtually all diesel cars emitted far more toxic fumes than in official laboratory based tests. Since 1 September, new models must now be tested on real roads, but the new data shows even this does not prevent high levels of fumes in slow traffic, when pollution is at its worst for drivers and other road users.
Emissions Analytics, a respected testing firm, measured the emissions from two diesel cars on rush hour journeys into and out of London. In the most congested three-mile stretch of the evening rush hour, a VW Golf and Vauxhall Insignia both emitted far more nitrogen oxides in their official real world tests – 42% and 118% more, respectively. read more »
