A recent report from the International Council on Clean Transportation (ICCT) finds that on-road nitrogen oxides emission levels of modern diesel cars are on average about seven times higher than the limit set by the Euro 6 emission standard, which went into effect in September 2014.
The ICCT - an independent research organisation - says that its report is the most comprehensive yet produced on the real-world behavior of the latest generation of diesel cars.
The study found remarkable differences between individual vehicle models, indicating that technologies for real-world clean diesels already exist but are not being consistently employed by different vehicle manufacturers.
The study is based on on-road tests of 15 vehicles using Portable Emissions Measurement Systems (PEMS). It covers more than 140 hours and 6,400 kilometers of driving, and provides the largest collection of public data on Euro 6 equivalent diesel cars currently available. Diesel vehicles make up about 50 per cent of all new cars in the EU. From September 2014 on, the Euro 6 standard applies to all new passenger car types.
