Almost a year after the Volkswagen emissions scandal, diesel vehicles are still emitting much more pollution when driven in real world conditions compared to testing. Many are taking steps towards reducing pollution, including the EU which has tightened emission regulations for September 2017 whereby diesel vehicles that emit more than double the laboratory limits for NOx road emissions will be banned from sale.
Newly elected London Mayor Sadiq Kahn has also vouched for change with London currently 15th out of 36 global cities for air quality, behind Berlin and Stockholm. The Mayor is consulting on plans to charge for the most polluting vehicles, expanding the Ultra Low Emission Zone, implementing a £10 Emissions Surcharge (additional to the London Congestion Charge), implementing clean bus corridors and a diesel scrappage scheme.
It will be interesting to see how London tackles their emission problems and whether this will result in other cities following suit, unlike the controversial London Congestion Charge.
