Commercial Aviation

The document outlines the difficulty of decarbonizing commercial aviation, noting that while it contributes around 4% of all-time global warming, it lacks the immediate clean technological fixes available to other sectors. It highlights the limitations of sustainable aviation fuels (SAF), the outsized impact of frequent fliers, and the role of non-CO2 emissions like contrails. The guide encourages reporters to scrutinize industry greenwashing, report on how climate change increases flight turbulence and heat-related disruptions, and consider demand reduction as a necessary strategy to meet 1.5 degrees Celsius targets.

• Commercial aviation is responsible for approximately 4% of all-time global warming when accounting for all emissions, including high-altitude gases and contrails, though its CO2 emissions alone account for 2.5% of the global total.
• Decarbonizing aviation is more difficult than other sectors because there are no obvious clean fixes; sustainable aviation fuel (SAF) is currently available only in small quantities at high prices, and electric planes or new designs are years away from commercial reality.
• A small minority of the global population is responsible for a disproportionate amount of aviation emissions, with 1% of people accounting for half of passenger air travel's emissions.
• Climate change is actively impacting aviation operations by disrupting air currents, which increases turbulence, and creating extreme heatwaves that reduce engine thrust and lift.
• Non-CO2 impacts are significant, with airline contrails contributing more than one-third of the industry's total global warming effect.
