日本語
本研究は、EU ETSが欧州の航空需要と供給に与える影響を分析。炭素価格ショックが国内線・EU域内線の便数を減少させる一方、域外線には影響がないことを発見。航空運賃の上昇も確認され、航空会社が炭素コストを運航効率維持で相殺する戦略を示唆。
English
This study assesses the impact of the EU ETS on air travel demand and supply in Europe. Using VAR with external instruments, it finds that carbon pricing shocks significantly reduce domestic and intra-EU flights, but not extra-EU flights. Airfares increase, and airlines adjust strategically to mitigate carbon costs while maintaining operational efficiency.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも航空業界へのカーボンプライシング導入が議論されており、本論文の実証手法と結果は、国内線・国際線への影響評価に示唆を与える。特に、便数と旅客数の非対称な減少は、航空会社の行動変化を理解する上で重要。
In the global GX context
This paper provides robust empirical evidence on how carbon pricing affects aviation, a sector often excluded from carbon markets. The findings on differential impacts across flight types and strategic airline responses are valuable for designing effective climate policies globally, especially as ICAO's CORSIA and regional ETS expand.
👥 読者別の含意
🔬研究者:Provides a rigorous empirical framework (VAR with external instruments) to identify causal effects of carbon pricing on aviation, useful for future policy evaluation studies.
🏢実務担当者:Airlines and aviation stakeholders can use the findings to anticipate operational and pricing adjustments under carbon pricing, informing carbon cost management strategies.
🏛政策担当者:Highlights that carbon pricing reduces domestic/intra-EU flights but not extra-EU, suggesting leakage risks and the need for complementary measures to ensure environmental integrity.
📄 Abstract（原文）
This study assesses the impact of the EU Emissions Trading Scheme (EU ETS) on air travel demand and supply in Europe. Using vector autoregression (VAR) methodology enriched with an external instrument, we analyse how carbon pricing shocks affect passenger numbers on domestic, intra-EU, and extra-EU flights across Europe, alongside examining the effect on the number of flights. This is done for the EU as a whole, and separately for Germany, United Kingdom, France, Italy, and Spain. We document significant reductions in domestic and intra-EU flights, while extra-EU flights are not found to be affected by carbon price shocks. Moreover, we show that carbon pricing policies lead to significant increases in air transportation prices. Overall, flight frequency is found to decrease more than passenger numbers, indicating airlines' strategic adjustments to mitigate carbon-related costs while maintaining operational efficiency. Our study emphasizes the importance of understanding these effects for informing future policy decisions and business practices in the aviation industry.
