Assesses charging infrastructure deployment practices, challenges, and emerging best practices in major electric vehicle markets. Statistically analyzes the relationship between public charging and electric vehicle uptake at the metropolitan area level to better discern local infrastructure variation, practices, and circumstances.
Assesses zero-emission heavy-duty vehicle technologies to support decarbonization of the freight sector in the 2025–2030 timeframe. Synthesizes data from the research literature, demonstrations, and low-volume commercial trucks regarding their potential to deliver freight with zero tailpipe emissions. Analyzes the emerging technologies by their cost of ownership and life-cycle greenhouse gas emissions for China, Europe, and the United States.
An analysis of advanced biofuel policies and recommendations for improving the effectiveness of policy support for emerging low carbon fuel technologies.
Legal brief summarizing public access to vehicle emissions data in the EU and US.
Analyzes the benefits of establishing separate engine CO2 standards in addition to full-vehicle regulations to specifically drive improvements in heavy-duty engine efficiency. Outlines a possible pathway for the development and implementation of separate engine CO2 standards for heavy-duty vehicles within the regulatory framework of the European Union.
Evaluates well-to-wheel greenhouse gas emissions from soot-free urban transit bus types in 20 megacities.
Reveals that the efforts made by multiple Transport Task Group (TTG) countries to promote and support policies and programs—including stringent tailpipe emissions standards, fuel economy standards, low sulfur fuels, and green freight programs—are in good alignment with the long-term perspective and pathways of the Transport Task Group defined in the G20 Energy Efficiency Leading Programme.
A summary of the technology and policy landscape encompassed by the phrase "new mobility," and survey of considerations involved in ensuring that new mobility developments support and advance the goals of clean transportation.
Examines the link between soybean and rapeseed biodiesel and palm oil in light of a new study on substitution effects.
Assesses the U.S. electric vehicle market and the factors that are driving it. Catalogues electric vehicle promotion activities. Identifies best practice policies in the 50 most populous U.S. metropolitan areas. Conducts a statistical analysis to discern links between the promotion actions and electric vehicle uptake.
Highlights important innovations and trends in diesel engines and emission control systems, some of which were not considered when the 2025 CAFE and greenhouse gas standards were finalized, yet promise to improve diesel passenger vehicles’ cost-effectiveness, especially for larger classes.
Summarizes the key barriers that impede the adoption of fuel-saving technologies in the trucking sector and discusses some of the ways policymakers can combat them.
Examines how the greenhouse gas and fuel economy standards have changed over time, how the auto industry in different regions has reacted, and discusses how the standards may evolve in the future.
Evaluates options for integrating electric vehicles into U.S. and European efficiency regulations based on cost-effectiveness and emission-reduction implications.
Summarizes important features and experiences of successful retrofit program efforts primarily in the U.S. and Europe, and also highlights the range of retrofit technologies that have been successfully used to reduce exhaust emissions (including diesel particulate and NOX emissions) from older, existing on-road and off-road diesel engines.
Summarizes the status of electric vehicle market in California through 2016, quantifying electric vehicle market growth across California cities and metropolitan areas.
Cost-effectiveness and potential analysis of technologies for the reduction of fuel consumption and greenhouse gas emission of heavy-duty vehicles in the European market, in the 2020–2030 timeframe.
Reviews the political science, regulatory, and economics literature to illuminate the international competitiveness impacts of motor vehicle emission standards.
Diesel vehicles in major markets produce over 50% more NOx than official certification limits indicate. Study links these excess NOx emissions to ~38,000 premature deaths worldwide in 2015—mostly in the EU, China, and India.
Investigates the market adoption trends of 27 heavy-duty vehicle technologies, presents 20 years of technology market penetration data, and analyzes the trends in selected technology adoption on tractor-trailers and rigid trucks in the world’s three largest automotive markets (the EU, U.S., and China).
