A sharp increase in revenue passenger miles drove both profits and fuel consumption on domestic operations up between 2014 and 2016 for U.S. airlines. Alaska Airlines again ranked first in overall fuel-efficiency, while the gap between it and the least fuel-efficient carrier, Virgin America in 2016, widened slightly to 26%.

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.
