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.
Concise overview of the RFS: history and current implementation, proposed reductions in 2014 volumes, biofuels categories, credit trading system.
Brazil has moved to control vehicle emissions, and early deaths from exposure to vehicle emissions are projected to decline by 50 percent in 2030. But if Brazil were to adopt best-practice controls on vehicles and fuels, it could cut health impacts by an additional two-thirds.
Without new limits on vehicle emissions and fuel sulfur content, early deaths from emissions of fine particles in India's urban areas will nearly quadruple by 2030. With such limits, India could reduce early deaths by 84 percent compared to business-as-usual in the same period.
