This briefing paper identifies key differences in the regulations governing certification of NOX emissions from diesel cars (Euro 6) and trucks (Euro VI) that help explain

That diesel emissions are harmful and toxic is an old story. But even after 20 year of global action to clean diesel up, it is still throwing up new and more difficult challenges; and that is an unfolding story. US, Europe and Japan have made emissions targets stringent, but diesel vehicles are struggling to lower emissions.

This report provides a summary of CO2 emission levels of new passenger cars and vans in the European Union in 2015.

Annual statistical portrait of technologies, fuel consumption, and GHG and pollutant emissions in Europe's passenger car, light-commercial, and heavy-duty fleets.

This paper explores recent trends in the market penetration of plug-in electric vehicles (PEVs) in selected countries around the world, and the implications of this for a potential transition to a fairly dominant PEV market presence within the next 15 years.

Several studies have found that taxing vehicle purchase or ownership on the basis of carbon dioxide (CO2) emissions reduces CO2 emissions.

The European Commission is preparing to extend the European Union's CO2 emissions regulation for passenger cars and light-commercial vehicles out to 2025–2030.
