We face a near tripling of the number of cars on the planet from 2010 to 2050, the vast bulk in emerging economies. Improved fuel economy is essential if we are to address some of the negative implications of this growth, such as pollution, congestion, energy and resource depletion, and environmental damage.

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

The 21st session of the Conference of the Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC) was held in Paris from 30th November to 11th December 2015.

COP21 aimed to achieve a new international agreement to keep global warming below 2 degrees centigrade in 2050 (compared with the climate of the pre-industrial era in 1850). Improved vehicle fuel economy is vital for mitigating the impact of climate change as part of package of measures to reduce carbon emissions from transport. GFEI was showcased throughout the conference.

GFEI's message to COP21 Paris 2015

GFEI's latest film makes a strong case for global action on fuel economy.

GFEI attended COP21 in Paris 2015 to discuss and promote the benefits of improved fuel economy. The benefits are many, not least of which are the huge carbon savings which achieving the GFEI targets would bring. With up to 33 gigatonnes up for grabs - as well as gains in energy security, resource waste and even air quality, this film lays out the strong rational for action on fuel economy now.

GFEI Fuel Economy State of the World 2016


The GFEI launched its Annual Report entitled ‘Fuel Economy State of the World 2016: Time for Global Action’ in late 2015.

The report reviews the recent progress and remaining challenges in fuel economy and highlights the new developments, trends, and examples of progress that the GFEI has helped to bring about.

‘100 for 50 by 50’


To mark COP21, GFEI is announcing ambitious action to improve fuel economy globally – our ‘100 for 50 by 50’ campaign. We are using the vital political momentum of the SDG, G20 and COP processes to get 100 countries to commit to our goals of an average 50% improvement in the fuel economy of all vehicles by 2050. Our research shows that this is possible using existing cost-effective technologies. Countries committing to this are expressing:

  • Global commitment – to publically support the GFEI’s target to double fuel economy of the global passenger vehicle fleet by 2050, and for new passenger vehicles by 2030.
  • Domestic commitment to develop and adopt national policies to improve fuel economy for new passenger vehicles, consistent with GFEI targets, recognising that each country starts from its own baseline.
  • Resources and engagement commitment to actively contribute to the efforts of the GFEI, which could include:
    • Sending representatives to the annual GFEI training summit
    • Dedicating staff time to develop fuel economy database and policies, in collaboration with GFEI partner organisations
    • Engaging in regional initiatives on fuel economy as appropriate, and provide technical or financial support to these efforts as available
