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 “real-world” emissions of diesel cars operating on the roads.

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 paper assesses the fleet characteristics and technology adoption of India’s ligh tcommercial vehicle (LCV) market during fiscal year (FY) 2014-15. The assessment

The market for agricultural tractors and construction equipment in India is growing rapidly. Without further regulatory action to control emissions from these sources, they are expected to surpass on-road vehicles as the predominant transportation-related source of particulate matter (PM) and nitrogen oxides (NOx) in the next 10-15 years.
