International airlines arriving in the European Union must purchase carbon emissions allowances starting in 2029 [1, 2].
The move expands the EU Emissions Trading System to aviation to help the bloc meet climate-change targets while managing industry pressure [3, 4].
Under the new rules, airlines will be required to pay for CO₂ emissions for flights arriving in EU member states from destinations located within 5,000 km [1, 2]. This distance limit defines the scope of the financial liability for carriers operating in the region [1].
However, the policy includes specific geographic exemptions. Flights arriving from the U.S. and China will not be subject to these carbon costs [1].
There is some disagreement regarding the final scope of the pricing mechanism. While some reports indicate the 5,000 km limit [1], other sources suggest the EU may eventually price emissions from all international flights regardless of distance [1].
The expansion of the carbon market is part of a broader effort to reduce the environmental impact of the aviation sector, a primary contributor to global greenhouse gas emissions [3, 4]. By requiring the purchase of allowances, the EU aims to incentivize airlines to adopt cleaner technologies and more efficient flight paths [3].

This policy signals a shift toward greater financial accountability for the aviation industry's carbon footprint. By exempting the US and China, the EU is likely attempting to avoid immediate diplomatic friction and trade disputes with its largest economic partners while still pressuring regional and mid-range carriers to decarbonize.
