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.

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.

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.

Long-haul trucks are responsible for the bulk of road freight CO2 emissions in Europe. However, at the time the heavy-duty vehicle CO2 standards were finalized in the European Union in 2019, there was little information available on zero-emission technologies.

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.

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.

Air pollution poses a risk to human health at levels even below the emission limits established by the World Health Organization in Europe.

The European Commission is currently developing the requirements for the upcoming Euro VII standards. This paper assesses the total manufacturing costs of the emissions control systems—including both engine and aftertreatment technologies—that will likely be required to meet these limits.

China’s fuel consumption standards for heavy-duty vehicles (HDVs) have progressed since Stage 1 was first introduced in 2012, and Stage 4 standards are currently in development.

The monitoring of on-board fuel consumption metering (OBFCM) data is aimed at preventing a growing gap between the certified and real-world CO2 emissions from trucks. This can only be achieved, however, if regulation mandates a certain accuracy for the OBFCM methods in real-world operation.
