- International Transport Forum Discussion Papers
The International Transport Forum at the OECD is an intergovernmental organisation with 52 member countries. It acts as a strategic think tank for transport policy and organizes an annual summit of ministers. Our work is underpinned by economic research, statistics collection and policy analysis, often undertaken in collaboration with many of the world's leading research figures in academia, business and government. This series of Discussion Papers is intended to disseminate the International Transport Forum’s research findings rapidly among specialists in the field concerned.

Examining Fuel Economy and Carbon Standards for Light Vehicles
Under the European Union’s Voluntary Agreement with car manufacturers,
average light vehicle CO2 emissions in 2004 were 12.4% below 1995 levels but
appeared unlikely to achieve the 25% reduction needed to reach the 140 g/km
target for “per vehicle” CO2 emissions for 2008. The EU is now considering a
regulatory approach to further reduce average vehicle emissions, in the form of
CO2 emission or fuel economy standards. Such standards have been used by
a number of countries, including the United States (although U.S. standards
have been little-altered since their 1975 promulgation), Japan, China, and
several others, and those that have been in existence for some time – e.g.,
those in the United States and Japan –have been successful in achieving their
targeted levels of new vehicle fuel economy.
The purpose of this paper is to examine various aspects of fuel economy
and carbon standards for light vehicles, including their rationale, methods of
establishing stringency, regulatory structure, and timing, with the hope of
assisting the decision process for new standards. Because the Corporate
Average Fuel Economy (CAFE) standards adopted by the U.S. in 1975 are the
longest-standing and most studied of the various standards now in existence,
much of the focus of this paper will be on the U.S. standards.
