CO2 emissions from transport rebounded in 2021, returning to their historical growth trend
Even with anticipated growth in transport demand, following the Net Zero Scenario requires transport sector emissions to fall by about 20% to less than 6 Gt by 2030. Achieving this drop would depend on the rapid electrification of road vehicles, operational and technical energy efficiency measures, the commercialisation and scale-up of low-carbon fuels, especially in the maritime and aviation sub-sectors, and policies to encourage modal shift to lower carbon-intensive travel options.
Electric car sales are accelerating, with China and Europe setting new records
After increasing in 2020 despite a depressed car market, sales of electric cars – battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) – nearly doubled year-on-year to 6.6 million in 2021. This brought the total number of electric cars on roads to over 16.5 million. As in previous years, BEVs accounted for most of the increase (about 70%).
Together, China and Europe accounted for more than 85% of global electric car sales in 2021, followed by the United States (10%), where they more than doubled from 2020 to reach 630 000.

Created in 1990, the AFC TCP seeks to make a significant contribution to address the opportunities and barriers to fuel cell commercialisation by fostering the development of fuel cell technologies and their application on an international basis, and conveying key messages to policy makers and the wider community as appropriate.
Created in 1979, the AMT TCP focuses on materials critical to fuel efficiency improvement for current and future transportation technologies. The AMT TCP conducts co-operative research activities on friction reduction, waste heat recovery, and lightweighting of vehicles. The TCP work programme includes the development of standard test methods, testing, demonstration and design guidelines.
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.
In operation since 1993, the HEV TCP provides a forum for global co-operation on the development and deployment of electric vehicles. It supplies objective information to support decision making, functions as a facilitator for international collaboration in pre-competitive research and demonstration projects, fosters international exchange of information, and it can promote projects and programmes for research, development, demonstration and deployment.
The aim of the Bioenergy TCP is to increase knowledge and understanding of bioenergy systems in order to facilitate the commercialisation and market deployment of environmentally sound, socially acceptable, and cost-competitive, low-carbon bioenergy systems and technologies, and to advise policy and industrial decision makers accordingly.
The Hydrogen TCP, founded in 1977, works to accelerate hydrogen implementation and widespread utilisation in the areas of production, storage, distribution, power, heating, mobility and industry. The Hydrogen TCP seeks to optimise environmental protection, improve energy security, transform global energy systems and grid management, and promote international economic development, as well as serving as the premier global resource for expertise in all aspects of hydrogen technology.
