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.
Assesses the design and effectiveness of fiscal and other incentives for electric vehicles in Germany, the UK, France, the Netherlands, and Norway, at both national and, through a set of ten case studies, regional and city levels.
Highlights the effects of disparities between real-world data and official road-load coefficients, used to set up vehicle type-approval test equipment, on fuel consumption and CO2 ratings for European passenger cars.
Takes a closer look at three potential alternatives for OBD regulatory requirements that can be incorporated into the China 6 proposal. The ICCT recommends adopting CA OBDII with China 6 emission standards.
Under current regulatory standards, the wide commercialization of diesel cars would significantly increase NOX and PM2.5 emissions, contributing to poor air quality and adding 150,000 premature deaths through 2050.
Evaluates the potential air-quality benefits of using shore-based electric generating facilities, as opposed to a ship's own engines, to supply power for operations (such as loading and unloading) while a ship lies berthed in port.
