This report reviews the progress OECD and ECMT countries have made in reducing transport sector carbon dioxide emissions and makes recommendations for the focus of future policies. It analyses over 400 abatement measures introduced or under development. Despite significant efforts on the part of some countries, transport carbon dioxide emissions have increased steadily over the last 10 years. Slowing the growth of these emissions will require more government action and an increasingly pro-active role from transport sector industries. The report identifies the policies most likely to be effective and emphasises the importance of energy efficiency improvements for cost-effective action on global warming. Co-benefits of reducing carbon dioxide emissions include improving the security of oil supply and improved mobility. Reform of vehicle taxation so that it is based on a vehicle's specific carbon dioxide emissions and strongly differentiated, is considered a top priority for Europe. Initiatives to promote fuel-efficient driving, biofuels, modal shift, road pricing, and use of emissions trading in aviation is discussed.
