The EV Transition Check: Measuring progress towards zero-emission for passenger cars in the European Union
The EV Transition Check distills key facts about the passenger car market in the European Union relevant to the upcoming European Commission Progress Report.
Reassessment of excess NOx from diesel cars in Europe following the Court Justice of the European Union rulings
Estimates the number of vehicle models in Europe that likely use what may now be considered a prohibited defeat device
It’s time for Europe to address diesel defeat devices once and for all
Over seven years after the Dieselgate scandal first broke, high emissions from diesel vehicles are still a widespread issue
Fiat-Chrysler, Renault-Nissan . . . who might be next?
The current investigations might not prove that Fiat-Chrysler or Renault-Nissan used defeat devices per se, but these recalls confirm that automakers can do more than just the minimum necessary to comply with the letter of the law and reduce emissions in real-world conditions.
FAQ: In-use NOx emissions from diesel passenger cars
As the story concerning in-use NOx emissions from diesel passenger vehicles continues to unfold, a number of questions concerning the ICCT’s past and on-going research into discrepancies between chassis dynamometer test emissions and on-road test emissions, have come up repeatedly. In response, we’ve put together this FAQ sheet, which we’ll try to update as needed. […]
EPA’s notice of violation of the Clean Air Act to Volkswagen
Investigation into “defeat device” allegedly used to circumvent emissions tests began with ICCT-sponsored research on in-use emissions from diesel passenger cars Highlights the global need for vigilant enforcement of air pollution laws by regulatory agencies in all vehicle markets The International Council on Clean Transportation applauds the U.S. Environmental Protection Agency and California Air Resources […]
Real-world exhaust emissions from modern diesel cars
Documents the discrepancy between type-approval and real-world NOx emissions from new diesel passenger cars. On average, on-road NOx emissions from the vehicles tested for this analysis were about seven times higher than the limits set by the Euro 6 standard.
[Press release] New ICCT study shows real-world exhaust emissions from modern diesel cars seven times higher than EU, US regulatory limits
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. This is the key finding from a new report published today in Berlin by the International Council on Clean Transportation (ICCT), an […]
In-use emissions testing of light-duty diesel vehicles in the U.S.
Results of a project by the Center for Alternative Fuels, Engines and Emissions at West Virginia University to conduct in-use testing of three vehicles, using a portable emissions measurement system, over a variety of test routes.
