Does cutting airport slots reduce climate impact? The case of Amsterdam airport
研究评估削减阿姆斯特丹机场时刻对减少温室气体排放的效果，发现短期减排有限，除非大幅削减长途航班，否则效果不显著，对制定可持续航空政策有参考价值。
This study evaluates the effectiveness of airport slot reductions as a strategy for mitigating greenhouse gas (GHG) emissions, focusing on Amsterdam Schiphol Airport. Following the Dutch Government’s decision to reduce slots from 500,000 to 440,000, we analyse various risk scenarios using the D’Hondt method for proportional slot allocation and the Fuel Estimation in Air Transportation (FEAT) model to estimate fuel consumption. Strategies include proportional slot cuts, prioritising short-haul flights, and shifting to rail alternatives. Results show that short-term emissions reductions are modest and do not scale with slot reductions unless long-haul flights are significantly curtailed. Moreover, aircraft up-gauging could lead to increased emissions if airline behaviour is not addressed. Our findings challenge the effectiveness of slot reductions as a climate strategy, highlighting the importance of targeting long-haul flights and adopting comprehensive policies to achieve substantial emissions reductions. The study offers critical insights for sustainable aviation policy development.
