China has pledged to reach a peak in the nation’s economy-wide CO2 emissions by 2030 and to reach carbon neutrality by 2060. This study uses cutting-edge emission modeling tools to assess the potential for reducing climate pollutants from advanced policy packages compared with currently adopted policies for China’s transportation sector.

The recently published heavy-duty vehicle certification data from the European Union are a valuable source of information to assess the values of the CO2 standards baseline, track the progress of truck manufacturers towards their reduction targets, and understand the various technology pathways chosen by manufacturers to decarbonize their fleets

This analysis estimates the number of charging points and hydrogen refueling stations needed to enable the transition to 100 percent sales of zero-emission Class 7 and Class 8 tractor-trailers by 2040 in the United States.

Market analyses by vehicle segment, weight category, manufacturer, and engine size are needed to optimize vehicle emission standards and testing requirements. In India, these are largely adopted from Euro standards to fit the Indian landscape, and that was the case with the Bharat Stage (BS) VI regulations that took effect April 1, 2020.

An upcoming review of the heavy-duty CO2 emissions standards in the European Union will consider several adjustments to the regulation, including the possibility of extending the CO2 emissions reduction targets to other vehicle segments, as well as setting specific targets for trailers.

Diesel, natural gas, and electric heavy-duty vehicles can be designed and manufactured with the capability of complying with the ultra-low NOx limits envisioned in the next set of California and federal HDV regulations. But that is not to say that the outcomes for each are equivalent.

In this paper, zero-emission heavy-duty vehicles refers to vehicles with maximum weight ratings greater than 3.5 tonnes (t) that are equipped with powertrain technologies that produce no tailpipe emissions of greenhouse gases and air pollutants. ZE-HDVs are battery-electric and hydrogen fuel-cell vehicles.

In the past decade, China has rapidly become the world’s largest electric vehicle market, accounting for half of the world’s electric vehicle sales and more than 90% of the stock of electric buses and trucks combined.

In December 2020, the Ministry of Ecology and Environment (MEE) of China updated the China IV emission standards for non-road mobile machinery.

This study analyzes the real-world emissions of seven Euro VI-D trucks and evaluates the avenues for extending the in-use PEMS test provisions to better capture a wider range of frequently occurring conditions in real operation. The analysis finds that urban operation is responsible for 50% to 90% of total NOx emissions from the trucks tested.
