Trucks & buses

Tailpipe CO2 emissions from heavy-duty vehicles have increase on average 2.2% annually since 2000. Trucks account for more than 80% of this growth. Vehicle efficiency standards, together with efforts to improve logistics and operational efficiency, are needed to slow growing emissions.

Heavy-duty vehicles emissions need to peak rapidly to decline in the coming decade

After dipping during the pandemic, in 2021 emissions from trucks and buses rebounded to roughly their previous level. As a result, emissions in this sector need to peak within the coming few years and begin to rapidly decline within the coming decade to reach Net Zero Scenario milestones. This equates to a fall of 16% by 2030 relative to their current level.

However, given historical trends and the 2021 rebound, emissions from trucks and buses are set to continue increasing, reaching record levels in the coming years. More countries need to adopt, strengthen and harmonise heavy-duty vehicle fuel economy standards and zero-emission vehicle (ZEV) mandates. Adoption of electric and hydrogen fuel-cell electric heavy-duty vehicles (HDVs) is needed now to enable emissions reductions in the 2020s and 2030s.
Our work

The mission of the AMF TCP is to advance the understanding and appreciation of the potential of advanced motor fuels towards transport sustainability. This is achieved by providing sound information and technology assessments designed to facilitate informed and science-based decisions regarding advanced motor fuels at all levels of decision-making.

The Combustion TCP provides a forum for interdisciplinary exchange and enables international collaborative research to advance the understanding of combustion processes to: accelerate the development of combustion technologies that demonstrate reduced fuel consumption and have lower pollutant emissions in transportation, power generation, industry and buildings, and; generate, compile and disseminate independent information, expertise and knowledge related to combustion for the research community, industry, policy makers and society.
