欧州16の航空会社グループの年次報告書・サステナビリティ報告書を分析し、Scope1のCO2総排出量や排出原単位の開示は進展している一方、Scope2・3、エネルギー消費、GHG除去、SAFや非CO2効果などの開示に大きなばらつきがあることを示した。任意KPIの乱立が比較可能性を損ない、グリーンウォッシュやグリーンハッシングのリスクも指摘する。CSRDやEU ETS、CORSIA、ReFuelEUなどの規制が改善を促すが、方法論の調和と明確化が不可欠だと結論づける。
English
Analyzing annual and sustainability reports from 16 major European airline groups, this study finds progress in disclosing core metrics like Scope 1 CO2 and emissions intensity, but persistent gaps and inconsistencies in Scope 2/3, energy use, GHG removals, SAF, and non-CO2 effects. Proliferation of voluntary KPIs undermines comparability and raises greenwashing and greenhushing risks. It concludes that CSRD, EU ETS, CORSIA, and ReFuelEU drive improvement but further harmonization and methodological clarity are needed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
欧州の航空セクターにおけるCSRD対応の実態は、日本でもSSBJ基準や有報でのScope3開示を進める上で貴重な先行事例となる。特にSAFや非CO2効果といった航空特有の指標の扱いは、日本の航空・運輸業界が統合報告書で開示を拡充する際の参考になる。
In the global GX context
This paper provides empirical evidence on how European airlines are adapting to CSRD and related frameworks, highlighting gaps in Scope 3 and sector-specific metrics like SAF and non-CO2 effects. It informs global disclosure scholarship on the challenges of harmonizing voluntary and mandatory KPIs in hard-to-abate sectors, relevant to ISSB and TCFD implementation.
👥 読者別の含意
🔬研究者:欧州航空会社のGHG開示の実証分析は、開示インフラ研究やScope3・SAF指標の標準化議論に有用なデータを提供する。
🏢実務担当者:航空・運輸業のサステナビリティ担当者は、Scope3やSAF開示のばらつきとグリーンウォッシュリスクを踏まえ、自社の開示精度向上に活用できる。
🏛政策担当者:規制当局は、任意KPIの乱立が比較可能性を損なう点を認識し、CSRDやCORSIAの運用における方法論の調和と明確化を検討すべき。
📄 Abstract（原文）
Abstract . The Aviation Zero Emission by 2050 (AZERO2050) study systemati cally evaluates the greenhouse gas (GHG) emissions reporting practices of Euro pean airline groups, focusing on both mandatory and voluntary key performance indicators (KPIs) as shaped by evolving regulatory frameworks and the long term ambition to reach net zero by 2050. By analysing annual and sustainability reports from 16 major airline groups, the research identifies significant progress in the disclosure of core metrics such as Total CO2 Scope 1 emissions and Emissions Intensity, reflecting growing regulatory alignment and stakeholder expectations. However, the findings also reveal persistent gaps and inconsistencies, particularly in the reporting of Scope 2 and 3 GHG emissions, energy consumption, GHG removals, and emerging metrics related to Sustainable Aviation Fuel (SAF) and non-CO2 effects—areas critical for tracking progress towards AZERO 2050. The proliferation of voluntary KPIs further complicates comparability due to a lack of standardization and clear definitions. These challenges are compounded by risks of greenwashing, where airlines selectively report favourable data, and greenhushing, where substantive achievements are under-communicated. The study concludes that while regulatory frameworks such as the CSRD, EU ETS, CORSIA, and ReFuelEU are driving improvements, further harmonization and methodological clarity are required to ensure transparency, comparability, and genuine progress toward aviation climate goals.
