Technology roadmap: Fuel economy of road vehicles

Current trends in energy supply and use are patently unsustainable – economically, environmentally and socially. Without decisive action, energy-related emissions of carbon dioxide will more than double by 2050 and increased oil demand will heighten concerns over the security of supplies. We can and must change our current path, but this will take an energy revolution and low-carbon energy technologies will have a crucial role to play. Energy efficiency, many types of renewable energy, carbon capture and storage, nuclear power and new transport technologies will all require widespread deployment if we are to reach our greenhouse gas emission goals. Every major country and sector of the economy must be involved. The task is also urgent if we are to make sure that investment decisions taken now do not saddle us with sub-optimal technologies in the long term.

Awareness is growing of the urgent need to turn political statements and analytical work into concrete action. To spark this movement, at the request of the G8, the International Energy Agency (IEA) is leading the development of a series of roadmaps for some of the most important technologies. By identifying the steps needed to accelerate the implementation of radical technology changes, these roadmaps will enable governments, industry and financial partners to make the right choices. This will in turn help societies make the right decisions.

It is crucial that governments around the world tackle the problem of poor vehicle fuel economy, and this document provides important guidance. Countries should explore how much fuel economy improvement is possible by different dates and design policies to push for maximum improvements over the coming 10 to 15 years. This roadmap and the companion IEA document Policy Pathway: Improving the Fuel Economy of Road Vehicles, provide policy makers with the guidance they need to develop their own plans and policies to make progress toward an efficient vehicle future.
