Slashing Flight CO2: Ditch Premium Seats!

Analysis suggests that cutting aviation's climate-heating emissions in half is achievable without reducing passenger numbers. Key strategies include eliminating premium seating, ensuring near-full flights, and utilizing the most fuel-efficient aircraft. These operational enhancements are presented as more effective than relying on sustainable fuels or carbon offsets.

The research, which analyzed over 27 million flights from 2023, identified significant variations in global flight efficiency. Airports in the US and Australia, particularly smaller ones, were noted for more polluting flights. Conversely, airports in India, Brazil, and Southeast Asia demonstrated greater efficiency.

Experts emphasize that these efficiency gains could also reduce the future need for sustainable fuels. Implementing policies such as efficiency ratings for airlines or higher landing fees for polluting aircraft could drive industry-wide improvements.
