A key message of the Fourth Assessment Report (AR4) of the Intergovernmental\nPanel on Climate Change is that improved energy efficiency is one\nof society�s most important instruments for combating climate change.\nThis article reviews a range of energy efficiency measures in the\ntransportation sector as discussed in AR4 and assess their potentials\nfor improving fuel efficiency. The primary focus is on light-duty\nvehicles because they represent the largest portion of world transport\nenergy use and carbon dioxide emissions; freight trucks, a rapidly\nexpanding source of greenhouse emissions, are also discussed. Increasing\nenergy efficiency can be achieved by improving the design and technology\nused in new vehicles, but vehicle technology is only one component\nof fleet fuel economy. Measures that create strong incentives for\ncustomers to take energy efficiency into consideration when buying\nand operating their vehicles will be crucial to policy success.
