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.
Summary of the rationale for supporting engine-based standards in the first phase HDV fuel efficiency regulation in India.
Overview of key technologies and best practices, with recommendations for future research.
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.
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.
Expands on the European Environment Agency's recently published provisional data for CO2 emissions from passenger cars sold in the EU in 2013, which shows that average emissions fell to 127 g/km, below the 2015 target.
Concise summary of a key component in the compliance mechanism of the RFS2.
Explains how compliance credit trading under the US CAFE standard is managed and executed in practice.
