This update adds one new data source, for a total of 14, covering 16 years, eight countries, and approximately 1.1 million cars. The analysis shows that, in the EU, the gap between official and real-world CO2 emission values continues to grow—from 9% in 2001 to 42% in 2016.

Investigates the gap between real-world and official CO2 emission values in the four largest vehicle markets in the world: China, the EU, Japan, and the United States. The analysis shows that the gap has increased in all markets since 2001. 

Finds that for cars, the cost for meeting a 2025 target value of 70 g/km (as measured in the New European Driving Cycle - NEDC) is between 250 and 500 euros higher than would be the case in a footprint-based CO2 target system.
