Surveys governments', automakers', and advocates' efforts to support development of the global EV market, and outlines an agenda to promote the global transition to a zero-emission vehicle fleet.
Extends an analysis of the gap between official and real-world fuel consumption and CO2 emission values for passenger cars in Europe and investigates the reasons for the increasing gap.
Analyzes results of emissions tests on 32 Euro 6 diesel passenger cars from 10 different manufacturers. Results show some automakers meeting diesel NOx emissions standards under more realistic driving conditions, while others lag badly.
Analyzes the fuel efficiency / carbon intensity of new commercial aircraft, and indicates the substantial gap existing between what is technological feasible and new aircraft currently on the market.
Inspection and maintenance (I/M) programs are key to identifying high-emitting vehicles and mitigating their impact on air quality and climate. This paper assesses best practices for I/M programs targeting heavy-duty vehicles and makes recommendations on how to improve HDV I/M programs in the future.
Analyzes the implications of a growing natural gas vehicle fleet on the emission benefits of the U.S. HDV “Phase 2” greenhouse gas rulemaking, synthesizing data on upstream emissions, vehicle emissions, and efficiency technology.
Surveys actions being taken by state and local governments and public utilities to facilitate electric vehicle deployment in the 25 largest U.S. metro areas. Presents city-specific analysis of consumer benefits and links between policies aimed at promoting EVs and market uptake.
Reviews China’s efforts to rein in air pollution from vehicles and presents a cost-benefit analysis of the introduction of stringent new vehicle emissions and fuel quality standards.
A survey of local- and provincial-level policies intended to control emissions from high emitters and older vehicles, and comparison with best practices.
