We face a near tripling of the number of vehicles 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) works to secure real improvements in fuel economy, and the maximum deployment of vehicle efficiency technologies across the world. This includes light and heavy duty vehicles, and the full range of technologies, including hybrid and fully electric vehicles. The Initiative promotes these objectives through shared analysis, advocacy, and through in country policy support, and tools.

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 hosts the secretariat.

HLPF logo

The United Nations High Level Political Forum (HLPF) is a vital opportunity review progress towards the achievement of the Sustainable Development Goals (SDGs).

The HLPF in 2018 has a thematic focus on ‘Transformation towards sustainable and resilient societies’, which includes a focus on SDG7 on energy. GFEI is encouraging countries that are undertaking voluntary national reviews (VNRs) to report progress on target 7.3 on energy efficiency, which aims to double energy efficiency by 2030. This corresponds with GFEI’s goal of doubling vehicle efficiency by 2030. GFEI will be sharing our latest work, including our wider focus on heavy duty vehicles as well as passenger cars and how fuel economy policy can support the transition to zero emission vehicles.

GFEI COP23 Update


GFEI’s new ‘COP23 update’ shares progress made since the COP21 Climate Summit in Paris. In particular, it showcases the extensive activities and action that GFEI has catalysed through its ‘100 for 50by50’ initiative. This has led to 40 new countries joining our work, taking the number to over 70. It includes summaries of recent activities in the past year and a progress chart for all the countries where GFEI works.

'100 countries for 50by50' campaign

‘100 for 50 by 50’


At COP21 GFEI announced 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 encourage 100 countries to commit to our goal of an average 50% improvement in the fuel economy of all light-duty 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
