Will the future RDE regulation be enough to restore trust in diesel technology?

The Volkswagen Group (including Audi and Porsche), Opel, Fiat, Renault, and now Daimler are recalling millions of diesel vehicles for a software update. All of these manufacturers claim their... The success of the RDE regulation will depend on the will of manufacturers to prove that they have learned a lesson from Dieselgate by beginning to focus on reducing real-world emissions, not just...

Real-world emissions testing on four vehicles

We commissioned the Laboratory of Applied Thermodynamics, of the Aristotle University of Thessaloniki, and its spin-off company, Emisia, to investigate real-world emissions of four Euro 6 passenger...

Laboratory and on-road emission testing of in-use passenger vehicles in India

Considering the overwhelming evidence of high in-use NOx emissions from diesel cars in Europe and the US, the impact of NOx emissions in human health, and the growing numbers of new diesel passenger...

International comparison of Brazilian regulatory standards for light-duty vehicle emissions

This paper aims to inform the next phase of PROCONVE for LD vehicles by assessing important components of PROCONVE L6 and their relative strengths and weaknesses compared with similar programs in...

[Press release] New Real-Driving Emissions regulation: A great step forward—though not yet far enough to fully control toxic nitrogen oxide emissions

Real-world NOx emissions from new diesel cars could still exceed the Euro 6 emission limit of 80 mg/km by a factor of three or more, even after the new RDE regulation takes effect, according to...

Real-Driving Emissions test procedure for exhaust gas pollutant emissions of cars and light commercial vehicles in Europe

Two legislative packages are currently under development to complete implementation of the new real-driving emissions (RDE) test procedure for measuring vehicle emissions in Europe. The goal is to...

Impact of improved regulation of real-world NOx emissions from diesel passenger cars in the EU, 2015−2030

NOx emissions from diesel cars in the EU have remained high, largely due to a growing gap between emission certification limits of Euro 4 and Euro 5 standards (measured in laboratory testing) and “...

Assessing real-world CO2 emissions using simulation and PEMS data

The Real Driving Emissions (RDE) testing procedure will introduce on-road testing as well as not-to-exceed emission limits for new passenger cars in Europe. However, for the time being, these on-...

The future of vehicle emissions testing in Europe (and beyond)

At the ICCT we have been analyzing the growing gap between official and real-world vehicle fuel consumption and CO2 emissions of passenger cars in Europe for a few years now. We showed for the first... To solve the problem underlying the growing gap between certification-test and in-use CO2 and NOx emissions, we will have to go beyond just introducing a new test procedure.
