The primary objectives of this paper are to explore methods for testing and certifying the fuel efficiency of HDVs and vehicle components in the established and emerging regulatory programs around the world and the implications for India, as policymakers there deliberate establishing a performance standard of their own.

Black carbon is the second largest contributor to human-induced climate warming, after carbon dioxide. International shipping is a major source of diesel black carbon emissions and not yet subject to international regulation.

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).

Marine vessels are a large source of greenhouse gas and air pollutant emissions, including CO2, NOX, SOX, particulate matter and black carbon, which impact local air quality, human health, and the global climate.

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
