The International Civil Aviation Organisation is in the process of finalising the design of a scheme – the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) – to address carbon dioxide emissions from international aviation.

To address the danger that greenhouse gas (GHG) emissions from aircraft pose to public health and welfare, the U.S. Environmental Protection Agency (EPA) is set to propose an aircraft CO2 emissions standard.

This working paper details and analyzes a global, transparent, and geographically allocated carbon dioxide emissions inventory for commercial aviation for calendar year 2018.

This study assesses the fuel efficiency of U.S. airlines on domestic operations in 2017 and 2018. Revenue passenger miles (RPMs) increased 10% and departures increased by 4% from 2016 to 2018. Fuel efficiency in terms of RPMs per gallon of fuel consumed improved by 3%.

Alternative jet fuels (AJFs) are among the few available in-sector approaches to reduce aviation sector emissions. Although the aviation sector has not played a prominent role in fuels policy to date, policymakers are increasingly incorporating aviation fuels into long-term strategies as the road sector is electrified.
