In 2011 the ICCT began studying airline operations to provide consumers, researchers, and policymakers with better information about airline efficiency and CO2 emissions. Our initial focus has been on the U.S. domestic market, which currently accounts for approximately one-quarter of global aviation CO2 emissions. Aviation fuel use in the U.S., moreover, is projected to grow almost 2% annually for the next 20 years. Working with researchers at the FAA’s National Center of Excellence for Operations (NEXTOR) at UC Berkeley, we developed a novel statistical approach allowing an apples-to-apples comparison of fuel efficiency independent of airline size, operating structure, and business model.
Fuel accounts for about a third of an airline’s operating costs, creating an incentive for airlines to manage their fuel consumption through technological and operational improvements. Nonetheless, our annual fuel efficiency rankings have identified a large (~26%) and stable fuel efficiency gap among U.S. domestic airlines, falling gains from fuel efficiency for U.S. airlines over time, and little correlation between the profitability an airline and its overall fuel efficiency. The research highlights the importance of effective policies to help constrain aviation emissions growth domestically and internationally.

Updates a benchmarking study of airlines' fuel efficiency in 2010. Overall, the fuel efficiency of U.S. airlines on domestic operations improved 2.3% from 2010 to 2012, not enough to meet U.S. greenhouse gas reduction goals, and the gap between best and worst did not change.
Quantifies the gaps in overall in-service fuel-efficiency between U.S. domestic passenger airlines, using publicly available data and accounting for differences in business operations across airlines.
