Summary of U.S. greenhouse gas emissions and fuel efficiency standards for medium- and heavy-duty engines and vehicles finalized August 2011.
A survey of the benefits of energy efficiency improvements for passenger vehicle tires, and of policies designed to promote those benefits in the EU, US, Japan, and South Korea.
Case study demonstrates how metrics that include vehicle and/or fuel weight could relax incentives for manufacturers to devote technological improvements to reducing fuel consumption rather than boosting performance.
Surveys the range of test cycles used to evaluate the efficiency of vehicles—including passenger cars and trucks, motorcycles, heavy-duty trucks and buses, and marine vessels—in order to inform ICAO discussion of a CO2 certification procedure.
Summarizes differences between size-based and mass-based vehicle standards and discusses their relative advantages and disadvantages.
Discusses initial ICCT work on sales‐weighted historical trends in new aircraft design attributes and their influence on aircraft efficiency, using design range as a first area of inquiry.
Estimates the sales and activity-weighted efficiency of new jet aircraft from 1960 to 2008 to argue that fuel price has been an inconsistent driver of aircraft efficiency, and that an aircraft CO2 standard is most likely to reduce emissions if it applies to all newly built aircraft from current production lines, not just to new designs.
