本研究は、欧州銀行が発行するグリーンボンドの利回りに影響を与える要因を分析。ESGスコアやスコープ1/2/3排出量、気候関連SDGsへの整合性は利回りに負の影響を与える一方、グリーンボンドラベルや非関連SDGsは正の影響を与え、投資家が具体的な環境指標を重視することを示唆。グリーンウォッシング懸念がグリーンボンドのプレミアム（グリーニアム）に影響する可能性を実証。
English
This study analyzes factors affecting yields of green bonds issued by European banks. It finds that ESG scores, Scope 1/2/3 emissions, and alignment with climate-related SDGs have a negative impact on yields, while the green bond label and non-relevant SDGs have a positive impact, indicating investors prioritize concrete environmental indicators. The results suggest greenwashing concerns may affect the greenium.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではグリーンボンド発行が増加しているが、グリーンウォッシング懸念も高まっている。本論文は、投資家が具体的な環境指標（スコープ1/2/3排出量やESGスコア）を重視することを示しており、日本の発行体が開示すべき情報の優先順位を考える上で示唆に富む。SSBJ基準や有報での気候関連開示の実務にも関連。
In the global GX context
This paper provides empirical evidence on how green bond yields are influenced by environmental performance indicators, addressing greenwashing concerns. It contributes to the global debate on green bond credibility and the role of disclosure (e.g., TCFD, ISSB) in sustainable finance. The findings are relevant for investors, issuers, and regulators worldwide.
👥 読者別の含意
🔬研究者:Provides empirical evidence on the determinants of green bond yields, highlighting the importance of granular environmental metrics over labels.
🏢実務担当者:Offers insights for banks issuing green bonds: investors reward concrete environmental performance (ESG scores, emissions) rather than just the green label.
🏛政策担当者:Suggests that regulators should encourage detailed environmental disclosure (e.g., Scope 1/2/3) to enhance green bond market credibility.
📄 Abstract（原文）
Banks play a pivotal role in supporting the real economy throughout the transition toward a more environmentally sustainable model. Among the initiatives available to them, the issuance of green bonds represents a concrete means of demonstrating a commitment to sustainable finance. However, for such initiatives to be credible, banks must ensure that green bond issuance translates into measurable and timely improvements in their environmental performance. This research stems from the skepticism around banks issuing green bonds, as a result of which they may not benefit from a greenium (a premium on the yield of green bonds in favor of the issuer), perhaps because they are not perceived by investors as reliable in implementing green projects. Consequently, investors may perceive the “environmental benefit” and allocation of bond proceeds as less direct and transparent, and the impact of green bank bonds as reduced. The findings document that the ESG score (comprehensive and per pillar), the GHG Scope 1, Scope 2 and Scope 3 emissions, as well as the alignment with the climate related SDGs (SDG-7 and SDG-13) exert negative, statistically significant impact on the yield. In contrast, the green bond label and the number of SDGs have positive, statistically significant effect on bond yields. This indicates that the green bond label or the alignment with the SDGs that are not relevant to green projects do not convince investors to accept lower returns, whereas more specific or relevant indicators do.
