Heavy-duty zero-emission vehicles: Pace and opportunities for a rapid global transition
Outlines steps needed to reduce greenhouse gas emissions from heavy duty vehicles to levels that help meet the transportation sector’s responsibilities under the Paris agreement.
A comparison of nitrogen oxide (NOx) emissions from heavy-duty diesel, natural gas, and electric vehicles
Compares the capabilities of these three powertrain types in meeting an ultra-low NOx standard across four key areas: feasibility, cost, health impacts, and climate impacts.
Barriers and opportunities for improving long-haul freight efficiency in China
Identifies key barriers and opportunities for improving the efficiency of long-haul trucking in China, including ways to leverage policy windows.
Current state of NOx emissions from in-use heavy-duty diesel vehicles in the United States
