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.

Aircraft efficiency metrics: Mass as a “What Is Transported” Term in Efficiency Standards

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.

Test cycles used to evaluate vehicle efficiency

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...

Size or Mass? The Technical Rationale for Selecting Size as an Attribute for Vehicle Efficiency Standards

Summarizes differences between size-based and mass-based vehicle standards and discusses their relative advantages and disadvantages.

Trends in Aircraft Efficiency and Design Parameters

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.
