Freight transport has severe negative impacts on the local air quality in many Asian cities, and contributes significantly to greenhouse gas emissions.

The purpose of this guidance document is to inform national governments in developing and emerging economies about some of the current sources of international funding that are available and that could be used to support national efforts to improve vehicle fuel efficiency.

This report evaluates the impact of transportation policies on worldwide oil consumption and greenhouse gas (GHG) emissions and the potential for the reduction of both out to 2030. Its analysis finds that policies adopted and formally announced since 2000 will dramatically reduce oil consumption and GHG emissions from the transportation sector.

Developing countries need to transition to a low-carbon transport sector now to avoid locking themselves into an unsustainable and costly future, says a report by the World Bank.

The transportation sector accounts for approximately one-fifth of global final energy consumption and will account for nearly all future growth in oil use, particularly for road vehicles. The right policy mix can allow countries to improve the fuel economy of road vehicles, which in turn can enhance energy security and reduce CO2 emissions.

This roadmap explores the potential improvement of existing technologies to enhance average fuel economy of motorised vehicles and provides recommendations to reduce the average fuel economy of road motorised vehicles by 30% to 50% by 2030.
