Fuel Economy in Major Car Markets

Technology and Policy Drivers 2005-2017

The Global Fuel Economy Initiative (GFEI) works to secure real improvements in fuel economy across the world, with the goal of doubling average fuel economy by 2030 for new cars and by 2050 for all cars. This report tracks progress on fuel economy for cars and light trucks in 18 major car markets.


About GFEI


GEFI logo

The Global Fuel Economy Initiative (GFEI) is a partnership between the International Energy Agency (IEA), the United Nations Environment Programme (UNEP), the International Transport Forum of the OECD (ITF), the International Council on Clean Transportation (ICCT), the Institute for Transportation Studies at the University of California-Davis, and the FIA Foundation. The Initiative works to secure real improvements in fuel economy and the maximum deployment of existing fuel economy technologies in vehicles across the world through shared analysis, advocacy, and the Cleaner, More Efficient Vehicles Tool for in-country policy support.

The Fuel Economy Policies Implementation Tool (FEPIT)

Fuel Economy Policies Implementation Tool (FEPIT) is a Microsoft Excel-based tool which allows countries to analyse potential outcomes of different policy options based on the characteristics of their vehicle fleets in a range of different scenarios.  It also aims to support countries as they seek to promote fuel economy policies.

FEPIT was developed by IEA and introduced to GFEI partners during the GFEI global training event held in Paris on 11-12 June 2015 in conjunction with the IEA Energy Efficiency Training Week, drawing together policy makers and technical experts for two days of practical information-sharing and networking.

Technology Roadmap: Fuel Economy of Road Vehicles

Published: 19 September 2012

This roadmap explores the potential improvement of existing technologies to enhance the average fuel economy of motorised vehicles; the roadmap’s vision is to achieve a 30% to 50% reduction in fuel use per kilometre from new road vehicles including 2-wheelers, LDVs and HDVs) around the world in 2030, and from the stock of all vehicles on the road by 2050. This achievement would contribute to significant reductions in GHG emissions and oil use, compared to a baseline projection.

Different motorised modes are treated separately, with a focus on LDVs, HDVs and powered two-wheelers. A section on in-use fuel economy also addresses technical and nontechnical parameters that could allow fuel economy to drastically improve over the next decades. Technology cost analysis and payback time show that significant progress can be made with low or negative cost for fuel-efficient vehicles over their lifetime use. Even though the latest data analysed by the IEA for fuel economy between 2005 and 2008 showed that a gap exists in achieving the roadmap’s vision, cutting the average fuel economy of road motorised vehicles by 30% to 50% by 2030 is achievable, and the policies and technologies that could help meet this challenge are already deployed in many places around the world.

This report has been released in tandem with another report the Policy Pathways: Improving the Fuel Economy of Road Vehicles - A policy package, which describes the policies needed to deploy more fuel economic vehicles in more detail.

Policy Pathways: Improving the Fuel Economy of Road Vehicles - A policy package

Published: 1 October 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 examples of good practices from countries with experience in implementing fuel economy policies for vehicles. The report, part of the IEA’s Policy Pathway series, 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.

The Policy Pathway series aims to help policy makers implement the IEA 25 Energy Efficiency Policy Recommendations endorsed by IEA Ministers (2011).
