Addresses several common misconceptions about light-duty vehicle fuel efficiency and greenhouse gas standards and focuses on Australia’s proposed light-vehicle CO2 standards and the effects they may or may not have on Australian motorists.

Provides a synthesis of information regarding the global development of hydrogen fueling infrastructure to power fuel cell vehicles. Compiles research on hydrogen infrastructure deployment, fuel pathways, and planning based on developments in the prominent fuel cell vehicle growth markets around the world.

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.


Summarizes how state and local governments are supporting the development of local electric-vehicle markets in the 25 most-populous U.S. metropolitan areas. Provides a quantitative estimate of the effective cost of owning and operating battery electric vehicles in those 25 cities.

Summary of the rationale for supporting engine-based standards in the first phase HDV fuel efficiency regulation in India.

Publication: Briefing

Overview of key technologies and best practices, with recommendations for future research.

Publication: Briefing

Details options for and benefits of leapfrogging the Euro 5/V LDV/HDV vehicle emissions standards, and instead progressing directly from Euro 4/V to Euro 6/VI.

Publication: Briefing

HDVs conforming to Euro IV and V standards frequently show poor real-world NOx emissions performance. Evidence indicates that new certification protocols in Euro VI resolve this problem, and Euro VI-compliant HDV NOx emissions meet expectations.

Publication: Briefing

Summary of technologies and policies to reduce direct emissions from cars, trucks, and buses, drawing on examples of other megacities' policy initiatives in the areas of clean fuels, new vehicle emission standards, and in-use vehicle programs.
