ナイジェリア上場企業148社の2011～2025年のパネルデータを用い、地球温暖化が企業の持続可能性（炭素排出開示・環境情報開示）に与える影響を分析。気温上昇は自主的な排出開示を促進するが、実際の排出削減努力とは負の相関があり、パフォーマティブな対応を示唆。大企業やサステナビリティ委員会設置企業は開示品質が高く、規制環境が開示と削減の関係を正に調整する。
English
Using panel data from 148 Nigerian listed firms (2011-2025), this study finds that rising global temperatures are positively associated with voluntary carbon disclosure but negatively correlated with actual emission reductions, indicating a performative sustainability response. Larger firms and those with sustainability committees show higher disclosure quality, and the regulatory environment positively moderates the disclosure-reduction link.

日本のGX文脈において
ナイジェリアの事例は、日本企業が新興国サプライチェーンにおけるScope 3排出の実態把握や、開示と実質削減の乖離（グリーンウォッシングリスク）を検討する上で参考になる。SSBJ基準の国際的な適用可能性を考える際の比較材料としても有用。
In the global GX context
This paper provides rare empirical evidence from sub-Saharan Africa on the gap between climate disclosure and actual emission reductions, relevant for global investors and regulators assessing greenwashing risks in emerging markets. It complements TCFD/ISSB frameworks by highlighting the moderating role of regulatory environments in driving substantive corporate climate action.

📄 Abstract（原文）
The intersection of global warming and corporate sustainability has attracted increasing scholarly and policy attention, yet empirical evidence from emerging markets—particularly Nigeria—remains thin. This study investigates the impact of global warming on corporate sustainability, specifically carbon emissions reporting and environmental disclosures, among 148 listed firms on the Nigerian Exchange Group (NGX) over the period 2011–2025. Drawing on a balanced panel dataset of 2,220 firm-year observations, the study employs fixed-effects and random-effects panel regression models, alongside system Generalised Method of Moments (GMM) estimation to address potential endogeneity. The theoretical underpinning integrates Stakeholder Theory, Legitimacy Theory, and the Resource-Based View. Control variables include firm size, leverage, industry type, GDP growth, inflation, regulatory environment, board composition, sustainability committees, and exposure to carbon-intensive sectors. Results reveal that rising average global temperatures and associated climate risk indicators are positively associated with voluntary carbon emission disclosures but negatively correlated with actual emission reduction efforts, suggesting a performative rather than substantive sustainability response among Nigerian listed firms. Larger firms and those with dedicated sustainability committees demonstrate significantly higher environmental disclosure quality. Firms operating in carbon-intensive sectors—oil and gas, cement, and power—exhibit the highest emissions but paradoxically produce more extensive, though selectively framed, disclosures. The regulatory environment, proxied by the Securities and Exchange Commission's sustainability disclosure requirements, moderates this relationship positively. These findings carry critical implications for regulators, boards, investors, and policymakers seeking to align corporate behaviour with climate imperatives in sub-Saharan Africa.
