UK diesel cars fail to meet EU emission norms
DIESEL CARS currently following Euro 5 emission norms and tested under urban driving conditions in the UK have been found to emit 17 times more nitrogen oxide (NOx) as compared to their petrol counterparts. NOx emissions were also six times more for certified diesel cars under the Euro 6 emission standards. This was revealed recently in a London Assembly report Driving awayfromdiesel. The report assumes significance as Europe is planning to adopt Euro 6 emission standards by September 2015. Normally, diesel cars are allowed to emit three times more NOx as compared to petrol cars under the current Euro 5 standard. However, in present circumstances, NOx emissions by one diesel car equals to that of 17 petrol cars meeting the same norm. The London Assembly report Drivingawayfromdiesel was prepared after the Supreme Court ordered the UK government in April 2015 to prepare a new air quality strategy to tackle high levels of NOx found in the atmosphere. According to the UK government estimates, diesel vehicles are responsible for 40 per cent of London's NOx emissions.
