ナイジェリアの大手銀行3行の5年間のサステナビリティ報告書を分析し、ESG用語の使用が増加している一方で、定量的で検証可能なデータが伴っていないことを明らかに。新たな指標「ESG Salience Index」を用いて、レトリックの流暢さが運用の透明性を上回っている「不可視問題」を指摘。銀行の貸出ポートフォリオによる環境コストがほとんど測定・報告されていないことを批判。規制当局や基準設定機関への提言を提示。
English
This policy brief analyzes five years of sustainability reports from three major Nigerian banks, revealing a gap between ESG rhetoric and quantitative, verifiable data. Using a novel ESG Salience Index, it identifies an 'Invisibility Problem' where the environmental cost of lending portfolios remains largely unmeasured. It recommends five actions for regulators and banks to bridge the gap between sustainability talk and reality.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
この研究は、日本の金融機関や規制当局にとっても示唆に富む。日本ではSSBJや有価証券報告書におけるサステナビリティ開示が進む中、開示の質と実質的な脱炭素行動の乖離は共通の課題である。特に投融資先の環境影響（Scope 3）の可視化は日本のGX政策においても重要であり、本稿の「不可視問題」の指摘は日本の金融セクターにも当てはまる。
In the global GX context
This study highlights a global challenge in ESG disclosure: the gap between rhetoric and operational transparency. It introduces a new metric (ESI) to quantify disclosure quality, relevant to global standard-setters like ISSB and regulators tackling greenwashing. The findings on the 'Invisibility Problem' of financed emissions underscore the need for mandatory, audited disclosure of portfolio environmental impacts, aligning with TCFD and transition finance frameworks.
👥 読者別の含意
🔬研究者:The ESG Salience Index provides a methodological tool for studying disclosure quality; the paper invites replication in other markets, including Japan.
🏢実務担当者:Banks should recognize that merely adopting ESG language is insufficient; they must develop systems to measure and report the environmental footprint of their lending portfolios.
🏛政策担当者:Regulators and standard-setters should consider mandating quantitative disclosure of financed emissions and using tools like the ESI to assess disclosure quality.
📄 Abstract（原文）
Between the period of 2019 to 2023, Nigeria's major leading banks dramatically increased their use of <span>global Environmental, Social, and Governance (ESG) terminology in their annual sustainability disclosures. </span><span>On the surface, this signals improvement. Beneath it, this policy brief, drawn from original research </span><span>analyzing five years of sustainability reports from three Systemically Important Banks (Access Bank, </span><span>Zenith Bank, and UBA), reveals a disturbing pattern: Nigerian banks have learned to talk the language of </span><span>global sustainable finance, but they have not always supported that language with quantitative and verifiable </span><span>data. </span><span>The study, based on a new measure, the ESG Salience Index (ESI), shows that rhetorical fluency </span><span>has surpassed operational transparency, leading to what the author calls the ‘Invisibility Problem’: the </span><span>environmental cost of the lending portfolio of a bank has been largely unmeasured and unreported, despite </span><span>tremendous quantities of sustainability disclosure. This brief suggests five pragmatic recommendations for </span><span>regulators, standard-setters, and the banking sector to bridge the gap between sustainability rhetoric and </span><span>reality.</span> <div> <span><br></span> </div> <div> <br> </div>
