Surveys fuel-saving technologies, presents an analysis of the U.S. market, outlines policy options and offers specific recommendations for the upcoming "Phase 2" U.S. rulemaking on GHG and fuel-efficiency standards
Comparison of official and "real-world" fuel consumption and CO2 emission values for passenger cars in Europe and the United States, which shows that the average discrepancy between them rose from less than 10% in 2001 to 25% in 2011.
Analysis of the extent to which upstream carbon dioxide and methane emissions associated with producing liquefied natural gas offset its potential climate benefit.
This study shows that without modification the existing EU biofuels mandate is unlikely to deliver significant carbon benefits. If, however, iLUC factors are included in the policy in future, the policy would be likely to achieve the targeted 50% carbon reductions.
Proposes methods for determining EV efficiency, energy supply GHG intensity, and other factors that provide a basis for calculating upstream emissions.
Analyzes the causes of high off-cycle NOx emissions from Euro IV/V heavy vehicles that threaten efforts to improve urban ambient air quality in Europe and in other countries that use the Euro regulation as a pattern, and recommends various measures to address the problem.
Study using satellite mapping data of historical and projected rates at which oil palm plantations in Indonesia and Malaysia have expanded and will expand onto peat soils
Summarizes and evaluates approaches to testing and certifying power-train systems and complete vehicles.
Argues that studies of the effects of palm oil plantation expansion in SE Asia have significantly underestimated GHG emissions from palm oil grown on peatland, and therefore underestimate the indirect land use change emissions from many biofuels.
Surveys technology and policy options available to China as it works to build a world-class vehicle emissions control program, drawing on experience in Europe, Japan, and the United States.
