本稿は、GCC諸国の石油ガス企業を対象に、IFRS S2の強制適用が気候関連開示の質、資本コスト、企業価値、収益変動性に与える影響を実証分析した。差分の差分法と構造方程式モデリングを用い、強制開示が開示品質を34.2%向上させ、資本コストを180ベーシスポイント低下させ、企業価値を31%上昇させることを示した。また、炭素集約度の高い企業ほど効果が大きく、リスク管理パフォーマンスが媒介要因であることを確認した。
English
This paper empirically examines the impact of mandatory IFRS S2 reporting on climate disclosure quality, cost of capital, firm valuation, and earnings volatility using a quasi-experimental design on 95 GCC oil and gas firms from 2018 to 2024. Difference-in-differences and structural equation modeling reveal that mandatory IFRS S2 improves disclosure quality by 34.2 percentage points, reduces cost of capital by 180 basis points, increases firm valuation by 31%, and lowers earnings volatility by 33%. The effects are stronger for high-carbon firms, and risk management performance mediates the relationship.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文は、IFRS S2に準拠した強制気候開示が企業財務に与える因果効果を実証しており、日本のSSBJ（サステナビリティ基準委員会）基準への移行を検討する企業や規制当局にとって重要な示唆を提供する。特に、任意開示と比較した強制開示の優位性を定量的に示している点は、日本の有報や統合報告書における気候関連開示の実務に直接的な示唆を与える。
In the global GX context
This study provides causal evidence that mandatory IFRS S2 reporting yields significant financial benefits—lower cost of capital, higher valuation, and reduced earnings volatility—supporting the global push for mandatory climate disclosure under ISSB, CSRD, and SEC rules. The heterogeneity analysis shows that high-carbon firms gain the most, reinforcing the need for robust disclosure infrastructure in carbon-intensive sectors during the energy transition.
👥 読者別の含意
🔬研究者:Provides causal estimates (DiD + SEM) of mandatory IFRS S2 adoption effects, useful for disclosure regulation literature.
🏢実務担当者:Demonstrates that mandatory climate disclosure can reduce cost of capital and increase firm value, encouraging proactive compliance.
🏛政策担当者:Empirically justifies mandatory climate reporting over voluntary regimes, especially for high-carbon industries.
📄 Abstract（原文）
The article's primary focus is on how IFRS S2 affects climate-related reporting on financial risk mitigation strategies in oil and gas companies in the Gulf Cooperation Council. This study takes advantage of the fact that there are varying levels in the regulatory needs across the six GCC states and has used a quasi-experimental design to establish the causality of this relationship. The United Arab Emirates and the Kingdom of Saudi Arabia (KSA), however, have chosen to adopt a regulated, mandatory framework. Additional GCC nations, like Bahrain, Oman, Kuwait, and Qatar, have kept these structures up to date and made them freely accessible. We estimate the difference-in-differences estimation and structural equation modeling results of 95 companies covering 2018 to 2024 (665 firm-year observations) to conclude that mandatory IFRS S2 Reporting significantly enhances climate disclosure quality by 34.2 percentage points. Furthermore, it has beneficial economic implications: a 180-basis-point lower cost of capital, a 31 percent higher firm valuation, and a 33 percent lower earnings volatility. Structural equation modelling shows that improved risk management performance is the mediating factor. When the analysis is cross-sectional, the effects are heterogeneous, and the benefits are magnified in firms with high carbon intensity. Causal interpretation has been supported using our extensive robustness tests. Findings from this research provide an innovative empirical basis for the influence of IFRS S2 on carbon-intensive industries. The research offers essential recommendations to policymakers and corporate executives seeking to address the challenges posed by financial risks and climate change in the context of the current energy transition, confirming the benefits of mandatory reporting systems over voluntary ones.
