Evaluation of real-world fuel consumption of light-duty vehicles in China: A 2021 update
The gap between real-world fuel consumption and emissions of carbon dioxide from light-duty vehicles (LDV), and their laboratory values, is increasingly apparent around the world, including in China. ICCT has been tracking the gap between real-world and type-approval fuel consumption of LDVs since 2017. This update reveals that the gap between real-world and official fuel consumption in China has widened from 14% for MY 2007 to 37% for MY 2021. The accelerated expansion of the gap clearly indicates the need for regulatory changes to reverse the trend and close the gap.
