<p>On June 30, the U.N. International Civil Aviation Organization (ICAO) agreed to shift the baseline year for CORSIA, a landmark carbon emissions offsetting scheme for airlines, in response to the COVID-19 pandemic’s effects on the industry. CORSIA, set to begin in 2021, requires airlines to buy credits to offset carbon emissions from international flights that exceed the baseline of average emissions in 2019-2020. The airline industry argued that using 2020 in the benchmark calculation would artificially lower the offset ceiling due to huge declines in flights this year.
