Adding to the pile of evidence: Recent on-road testing results for CO2 and exhaust emissions from Euro 6 light-duty vehicles in the EU

In late 2015, in the immediate aftermath of the revelations about Volkwagen's cheating on vehicle certification tests in the United States, we commissioned Emissions Analytics, a commercial testing...Summarizes the Emissions Analytics testing on nitrogen oxides (NOx) and particulates, both of which pose significant health problems, and CO2 which is vehicles' main contribution to climate pollution...

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.

Will a new test procedure solve the problem? Latest developments on EU vehicle testing

Over the last few weeks, we published two major reports on the real-world emission behavior of passenger cars in Europe. The first one talked about air pollutant emissions, specifically nitrogen...Two recent ICCT reports clearly demonstrate the serious on-road problem for CO2 and NOx emissions in Europe. The European Commission is working on it, but the approaches chosen to address the real-...

Inertia classes, vehicle emissions tests, and the dead hand of the past

Test procedures are a key feature of any system of regulating vehicle emissions. Vehicle emissions testing* involves running a vehicle on a chassis dynamometer, which (among other things) simulates...The current system of using inertia classes for vehicle emissions testing is an anachronism, kept in place by force of habit rather than force of logic. And it has the bad effect of allowing...
