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.
Proposes a rapid, comprehensive policy response not only to deal with defeat devices but also to identify vehicle models with high real-world emissions relative to test-cycle performance and improve current compliance and enforcement programs.
Technical summary for policy makers of the status of hybrid vehicle development in the United States. First in a series of technical briefing papers on trends in energy efficiency of passenger vehicles in the U.S.
Summary based on the provisional data recently released by the European Environment Agency. All manufacturers have achieved their 2015 targets, with average emissions of 123.3 g/km in 2014, a decrease of 3% compared to 2013.
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.
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.
