Mind the Gap 2015: Closing the chasm between test and real-world car CO2 emissions

External Data Spec Published 15 Jan 2016
Report of the European Federation for Transport and Environment: The system of testing cars to measure fuel economy and CO2 emissions is utterly discredited. This report analyses the gap between test results and real-world performance and finds that it has become a chasm, increasing from 8% in 2001 to 31% in 2012 and 40% in 2014. Without action this gap will grow to nearly 50% by 2020.
