This brief presents the technical details and benefits of leapfrogging to Euro VI heavy-duty emission standards and Euro 6 light-duty emission standards rather than progressing through Euro 5/V.

Heavy Duty Vehicles conforming to Euro IV and V standards frequently show poor real-world NOx emissions performance. Evidence indicates that new certification protocols in Euro VI resolve this problem, and Euro VI-compliant HDV NOx emissions meet expectations.

In many regions of the world, older, high-emitting vehicles account for a small percentage of the overall vehicle fleet but a disproportionately large share of total emissions. It is estimated that these vehicles may be responsible for more than 50% of particulate matter (PM) and black carbon (BC) emissions by 2020 (Yan et al., 2011).

This paper provides a summary of recent data for real-world fuel consumption of HDVs—specifically, tractor-trailers—in three regions: the United States, China, and the
