Calculates the fraction of biomass carbon removed from disturbed or cleared forests that is retained in wood products (not emitted to the atmosphere).
Actions that reduce or eliminate HFC-134a emissions can make an important contribution toward lowering the overall climate impact of the global auto fleet. This paper assesses alternate refrigerant emissions and their climate impacts.
Builds on more detailed explanations in past WLTP doucments and presents, for discussion, a proposal for defining inertia classes for the WLTP GTR.
This paper was submitted to the UNECE GRPE informal subgroup on the development of a worldwide harmonized light vehicles test procedure (WLTP-DTP) on the issue of inertia classes to be used in the development of the WLTP.
Summarizes key steps in fuel economy data collection and verification under the U.S. corporate average fuel economy system.
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.
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.
Overview of low-carbon fuel related standards in various stages of development and implementation in the U.S., California, Europe, and the UK.
