IEA (2012), "Policy Pathway - Improving the Fuel Economy of Road Vehicles 2012", IEA, Paris https://www.iea.org/reports/policy-pathway-improving-the-fuel-economy-of-road-vehicles-2012
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. Improving the Fuel Economy of Road Vehicles highlights lessons learned and provides examples of good practices from countries with experience in implementing fuel economy policies for vehicles. This report outlines key steps in planning, implementation, monitoring and evaluation. It complements the IEA Technology Roadmap: Fuel Economy for Road Vehicles, which outlines technical options, potentials, and costs towards improvement in the near, medium and long term.
