日本語
本論文は、銀行のネットゼロ公約（SBTi、NZBA）が化石燃料融資に与える影響を実証分析。SBTi公約は融資行動に影響を与えないが、NZBA公約は相対的な融資削減をもたらすものの、完全な撤退には至らない。また、NZBA加盟は株価に正の反応を引き起こすが、これは同業他社と共同で加盟した銀行に集中しており、カルテル的な行動を示唆する。ただし、金利上昇や化石燃料企業の投資制限は確認できず、カルテル説は完全には支持されない。
English
This paper empirically examines the impact of banks' net-zero commitments (SBTi and NZBA) on their fossil fuel lending. It finds that SBTi commitments have no effect, while NZBA commitments lead to relative reductions in lending, though far from full divestment. Stock market reactions are positive for NZBA commitments, especially when banks join jointly with peers, suggesting possible cartel-like behavior. However, no evidence of higher interest rates or reduced capital expenditures for fossil fuel companies, so the cartel theory lacks full support.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の銀行もNZBAに参加しており、本論文の知見は、こうした連合が実質的な脱炭素化に寄与するか、あるいはグリーンウォッシュに過ぎないかを評価する上で重要。SSBJや金融庁の気候関連開示基準にも示唆を与える。
In the global GX context
This paper contributes to the global debate on the effectiveness of voluntary climate initiatives in banking, relevant for TCFD/ISSB reporting and transition finance. The findings caution against over-reliance on voluntary pledges and highlight the need for regulatory oversight.
👥 読者別の含意
🔬研究者:Provides robust empirical evidence on the impact of net-zero banking alliances, useful for further studies on transition finance and greenwashing.
🏢実務担当者:Banks can assess the real effects of joining net-zero alliances and consider strategic implications for lending and reputation.
🏛政策担当者:Offers insights into whether net-zero banking coalitions effectively reduce fossil fuel financing or require stronger regulation.
📄 Abstract（原文）
In response to public pressure, large banks have made a flurry of commitments to align their lending with net zero initiatives. Proponents of these initiatives hoped that reducing fossil-fuel lending would benefit the climate, while critics argued that climate banking initiatives were either pure greenwashing or even illegal cartels. Existing analyses present mixed results on whether banks truly decarbonize their lending after net-zero commitments and whether net-zero banking can reduce fossil fuel extraction. I show that when banks commit to set decarbonization targets vetted by the Science Based Targets Initiative (SBTI), they do not subsequently change their fossil fuel lending practices. In contrast, commitments to the now-defunct Net-Zero Banking Alliance (NZBA) were followed by significant relative reductions in fossil fuel lending, although these reductions fell far short of full divestment. Stock market prices do not react to SBTI commitments, but NZBA commitments yield a positive price reaction. I find that both positive stock market returns and reductions in lending by NZBA members are concentrated in banks that announced their membership in the alliance jointly with their regional peers or competitors, rather than banks that joined individually. While these results suggest cartel-like action, the cartel theory lacks full support: net-zero commitment banks do not charge higher interest rates on fossil fuel loans, and fossil fuel companies' ability to make capital expenditures is not reduced.
