An ICCT survey reveals how many diesel cars are still circulating in Italy and Europe with NOx emissions above the limits

March 24, 2023 – 5 p.m.

More than 7 years after the dieselgate scandal, an investigation by the International Council of Clean Transportation (ICCT) has made aanalyzes broad spectrum on vehicle emissions circulating in Europe. Italy is among the countries with the highest number of diesel cars with NOx emissions result “unnatural” Or “extremein real tests. A report that unveils the figures for makes and models and which will certainly lend itself to strengthening the position of environmentalists regarding the ban on new ICE cars from 2035 and the Euro 7 standard.

THE EUROPEAN SURVEY ON NOx EMISSIONS FROM DIESEL CARS IN TRAFFIC

The ICCT report clearly indicates that I NOx Emission Test Results more than 200 diesel car models sold from 2009 to 2019 in Europe. The researchers looked at the data from the homologation and RDE tests against the results from the independent tests. The analysis found levelssuspectsNOx emissions in at least 77% of cars against type approval testing and up to 100% of vehicles in independent testing likely to have a defeat device. Of the 219 vehicle models tested:

  • 209 they showed suspicious emissions in at least one test, with the likely presence of a defeat device.
  • about 66% tested vehicle models showed emissions “extreme”, indicating the certainty of the presence of an emissions modification plant.

IN EUROPE 37 MILLION DIESEL CARS HAVE NOX PROBLEMS

The ICCT report estimates that in the EU and UK were sold approx. 53 million Euro 5 and Euro 6 homologated diesel cars before the introduction of the Real Driving Emissions (RDE) test cycle. About 24 million diesel cars sold have “suspicious emissions” and probable handling, of which 16.3 million have “extreme emissions” and known handling. Italy, being one of the 5 large representative markets of Europe, inevitably takes the lead in this survey, after Germany, France and the United Kingdom and ahead of Spain, for the number of diesel cars with extreme NOx emissions. Only in Italy circulate according to the study 1.9 million diesel cars with emissions well above the homologation limit And 2.6 millions of diesel cars with suspicious emissions.

MAKES AND MODELS OF DIESEL CARS WITH NOX EMISSIONS BEYOND THE LIMITS IN ITALY

Among the manufacturers who, according to the analysis, would have placed a more vehicles with excessive NOx emissions There is volkswagen band. However, relative to sales, the weight of diesel cars with suspicious and excessive emissions is attributed to Nissan-Renault, Groupe PSA, Ford, General Motors, Hyundai Motor Company and Volvo.

As a result for some best selling diesel car models, the probability or certainty that an emission treatment device was used during type approval is increased. There Volkswagen Passat 2.0 TDI and Renault Clio 1.5 dCI are the most numerous of the models homologated according to the Euro 5 standard. The adoption of the Euro 6 homologation protocols has considerably reduced the number of cars whose emissions exceed the legal limits, but the presence of Peugeot 308 1.6HDi Euro 6 this is confirmation that the “problem” has not completely disappeared. “These measures alone cannot clean up the tens of millions of diesel cars that continue to emit NOx emissions many times over the legal limit.“, reports the ICCT. “It is time for EU Member States and the UK to fully tackle the problem of excess NOx from diesel cars.”.
