Fuel Prices Aren't Airlines' Only Headache.

The article focuses on the challenges facing the aviation industry's Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), a program by the International Civil Aviation Organization (ICAO) aimed at offsetting CO2 emissions from international flights above 85% of 2019 levels. Although CORSIA will become mandatory for most ICAO member states by 2027, airlines have been reluctant to fully engage due to high costs of sustainable aviation fuel, limited efficiency gains, and uncertainties about future regulatory changes, particularly from the US and European Union. The scheme primarily relies on carbon credits, many of which are avoidance units with varying reliability, raising concerns about environmental effectiveness and reputational risks. The article suggests that while CORSIA represents a rare international climate effort, its current design and enforcement limitations hinder its potential impact on reducing aviation emissions.
