Improvements in the average fuel consumption of light-duty vehicles have slowed in recent years, significantly below the rate of annual improvement needed to stay on track with global climate goals.

The fuel economy of new light-duty vehicle sales will need to improve by about 3.7% per year on average to stay on track with global climate goals. The most effective policy proven to drive such improvements is vehicle efficiency (or fuel economy) standards. Standards in some countries already require improvements at or above this rate. While recent extensions in the standards in Japan and the European Union, and a draft proposal in China are promising signs, the ambition of standards in the United States remains uncertain . Meeting the target globally will mean extending the scope of standards between where they currently exist and ratcheting up their stringency where they do not. Tightening the rules governing vehicle compliance during tests, and setting up frameworks to ensure these reflect real-world driving, are essential to ensure that all stakeholders make meaningful progress.

Key findings
Factors influencing passenger transport energy use, 2015-2018
OpenEnergy use in transport continues to grow, despite efficiency improvements
In transport, despite improvements in vehicle efficiency, energy use continues to grow. Amongst other factors, sales of new, more efficient vehicles have slowed, consumers prefer larger cars, and typical vehicle occupancy rates have fallen.
Average fuel consumption of new light-duty vehicles sold, 2005-17, and SDS trajectory to 2030
OpenFuel economy standards under real-world driving conditions must become significantly more stringent
Global average fuel consumption of new cars sold in 2017 improved only 0.7% year-on-year, slowing from the average 2005-16 improvement rate of 1.85% per year. To get on track with the SDS, which is aligned with the 2030 GFEI targets, annual improvements of 3.7% are needed. It is vital that standards become significantly more stringent and that vehicles comply with them in real-world driving conditions. Ambitious but achievable CO2 standards passed by the European Union and stricter standards in China inspire confidence, and rapid EV adoption will also help achieve efficiency goals.

Our work
The Global Fuel Economy Initiative (GFEI) – a partnership of 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 – works to secure real improvements in fuel economy and the maximum deployment of existing fuel economy technologies in vehicles across the world.
