The European Union plans to extend its carbon pricing scheme to international flights within a 5,000km radius of Frankfurt Airport, set to launch in 2029. The move aims to fund green aviation technologies and fuels but will increase costs for airlines, particularly short-haul budget carriers. Burning jet fuel emits over three tonnes of CO₂ per tonne, with greenhouse gas permits trading above €80 per tonne.

Researchers estimate the tax could add roughly €24 to a Paris-to-Istanbul flight, representing less than 10% of total costs. Legacy carriers like Air France-KLM and Lufthansa may benefit from a more level playing field with non-EU competitors such as Emirates and Turkish Airlines. However, low-cost airlines face greater strain due to price-sensitive customers.

University of Antwerp studies show Ryanair passengers exhibit high price elasticity (-2.07), meaning a 10% price hike could slash sales by 20%. Ryanair CEO Michael O'Leary warns these taxes will push travelers toward budget options, though existing customers may feel squeezed by rising ticket prices.
