International comparison of light-duty vehicle fuel economy
The Global Fuel Economy Initiative (GFEI) has been tracking worldwide average fuel economy of new vehicles and how it has evolved since 2005. Between 2005 and 2008, the rate of fuel economy improvement was not fast enough to reach the long term goal fixed by the GFEI in 2030: the average global fuel economy of new light duty vehicles (LDVs) should be cut by half (in l/100km or gCO2/km) by 2030. Have recent fuel economy policies developments accelerated the rate of improvement of new vehicle average fuel economy? This update containing new data analysis for years 2010 and 2011 sheds light on the latest improvement of new light-duty vehicle average fuel economy in most of the big markets worldwide.
