The GFEI brings together some of the leading global experts in the field of fuel economy. The data and research work which we do builds on that expertise and has led to the development of the only global data on fuel economy trends. This material not only adds to the level of global understanding of the issue, but also underpins our advocacy and in-country capacity-building.

GFEI: Delivering Sustainable Development Goal 7

GFEI: Delivering Sustainable Development Goal 7 Report

This report highlights GFEI's contribution to helping countries work towards delivering Sustainable Development Goal 7. The report was published to coincide with the UN High Level Political Forum in July 2018, which included a focus on energy efficiency as part of a review of SDG7. The report also includes a special case study of GFEI’s work with Jamaica.

At TRB 2017, Pierpaolo Cazzola shared GFEI’s latest fuel economy benchmarking study, which examines global progress in improving average fuel economy over the decade from 2005 to 2015. The new report is unique in its scale and comprehensiveness, covering more than 80% of the global vehicle market. It extends and enhances previous research that GFEI has published regularly since 2011 by including a longer time series, an updated in-depth exploration of fuel economy drivers in 17 countries and a new section on trends in vehicle prices globally.

Can we reach 100 million electric cars worldwide by 2030?


Working paper 16 is part 2 of a study of the potential to achieve a particular target of electric and plug-in hybrid vehicle sales worldwide by 2030.

It explores the question ‘Can we reach 100 million electric cars worldwide by 2030?’ using modelling/scenario analysis.

Working Papers

A series of research studies conducted by ourselves and our partners into issues about fuel economy.



In a GFEI Working Paper entitled ‘How vehicle fuel economy improvements can save $2 trillion and help fund a long-term transition to plug-in vehicles’, Lew Fulton of University of California at Davis argued that fuel economy improvements from conventional internal combustion engine cars could save $2 trillion over the next decade, resources which could in part be used to help offset the costs of developing a global market for electric vehicles since the savings are estimated to be at least four times bigger than these costs.
