new diesel vehicles are as much as more than 25 times over the legal contamination limit, a new research study into manufacturer emissions tests has revealed.
The worldwide Council on clean transportation (ICCT) discovered the typical vehicle creates seven times more nitrogen oxides than the Euro 6 standard which came into impact last month.

Just one of the 15 vehicles that were tested satisfied the 60mg per kilometre target with the worst result hitting a staggering 2,000mg per km.
• Diesels triggering unlawful air contamination across the UK
Dangerous levels of nitrogen oxides have been linked to countless premature deaths in the UK as well as the increasing popularity of diesel vehicles has been a big factor. It’s led London Mayor Boris Johnson to float the concept of charging diesel drivers an additional congestion charge.
The British contamination tests, brought out by Emissions Analytics, exposed the Mercedes C200 as well as Citroen C4 Cactus created three times the limit – however it stated it might not release the whole data for all the tests.
The tests were conducted in real-world conditions as well as included quick bursts of acceleration as well as longer periods travelling at 60mph. That’s rather different to the official tests which are conducted in a managed lab with smooth as well as gentle acceleration. The ICCT stated the results that broke the limit were recorded during typical driving as well as not at extreme moments.
• £11million investment in hydrogen fuel
Vicente Franco, an ICCT researcher as well as research study author, stated the results proved some manufacturers were establishing the right innovation however it wasn’t necessarily being utilized correctly. Selective catalytic reduction tech, for example, is calibrated by manufacturers to work at its peak during the official tests rather than in genuine world driving.
