Compares official laboratory-test and on-road nitrogen oxide (NOx) emissions for 541 Euro 5 and Euro 6 diesel passenger cars, representing 145 of the most popular European models.

A report investigating the real-world emissions of four Euro 6 passenger cars—one gasoline and three diesel vehicles with different aftertreatment technologies, tested under variable conditions. The investigation was conducted by the Laboratory of Applied Thermodynamics, of the Aristotle University of Thessaloniki, and its spin-off company, Emisia.

Despite the anticipated decline in diesel car sales future carbon dioxide (CO2) standards in the EU can still be met even if new-car diesel share falls as low as 15% by 2025. The net compliance cost for reaching a 70 g/km (NEDC) target by 2025 would decline by €10–€280 per vehicle, if the diesel market share were to drop to a level as low as 15%.

Diesel vehicles in major markets produce over 50% more NOx than official certification limits indicate. Study links these excess NOx emissions to ~38,000 premature deaths worldwide in 2015—mostly in the EU, China, and India.
