State of Clean Transport Policy

Tracking the development of clean transport policies worldwide

The 2014 State of Clean Transport Policy summarized recent progress in national and international regulations intended to reduce energy use, mitigate climate change, and control air pollution from motor vehicles and fuels in major vehicle markets. The report quantified the benefits associated with environmental policies for light-duty and heavy-duty vehicles, marine vessels, aircraft, and fuels in terms of reduced greenhouse gas (GHG) emissions and local air pollution, fuel savings, and benefits to public health. It also examined the additional benefits that could be gained through the wider adoption of world-class policies.

This new, online version of the State of Clean Transport Policy aims to provide up-to-date, relevant international comparisons of adopted policies for clean vehicles and fuels, track progress toward established targets, identify new policy options, and assess the potential impact of these options on the environment, public health, and the economy. In addition to simplifying the task of keeping this information up to date, the online format will allow for more links to current research by the ICCT and others, and to detailed background information at

Contents are organized by section, focused on policies to reduce GHG emissions and energy use, improve air quality, and reduce emissions of short-lived climate pollutants.
