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.

Key findings

CO2 emissions from trucks and buses in the Net Zero Scenario, 2000-2030


Heavy-duty vehicles emissions need to peak in the next year and begin to decline

The Covid-19 pandemic led to decreased transport activity in 2020, reducing bus and truck CO2 emissions 5% from 2019. Although emissions are expected to rebound in 2021, for the Net Zero Emissions by 2050 Scenario they need to peak in the next several years and then begin to decline, averaging year-on-year decreases of 2.1% from 2021 to 2030. To achieve this reduction in emissions, more countries need to adopt heavy-duty fuel economy and CO2 emissions standards as well as zero-emission vehicle mandates (and existing ones need to be made more comprehensive and stringent to spur adoption of zero-emission technologies). Rapid electrification of buses and the deployment of hydrogen and electric medium- and heavy-duty trucks, along with strategic infrastructure deployment, are needed in this decade to pave the way for large-scale battery and fuel-cell truck adoption in the 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.
