本論文は、Earnings Callのテキスト分析から得られた気候変動感情指標を用いて、企業の気候変動に対する楽観性の経時変化と独立取締役の影響を分析。楽観性は時間とともに上昇傾向にあり、独立取締役は当初楽観性を抑制するが、その効果は減少する。気候関連の企業コミュニケーションが戦略的・経済的考慮に基づくようになっていることを示唆。

Optimism increases over time; independent directors initially dampen it but effect diminishes. Findings suggest climate communication shifts from symbolic to strategic, with implications for governance, disclosure, and investor assessment.

📄 Abstract（原文）
We analyze the evolution of climate change sentiment in firms over time and the role of independent directors using sentiment metrics developed by Sautner et al. (2023). These metrics, derived from advanced textual analysis of earnings calls, capture overall sentiment, positive sentiment, negative sentiment, and specific metrics for physical risk, regulatory risk, and new business opportunities. Our findings reveal a positive trend in sentiment, driven by increased optimism and reduced negativity. Regulatory risk sentiment shows rising optimism, while physical risk sentiment remains stable. Independent directors initially dampen optimism, but this diminishes over time, highlighting sustainability’s strategic value. These findings suggest that climate-related corporate communication is increasingly driven by long-term strategic and economic considerations rather than symbolic statements. The results demonstrate the role of governance in shaping how firms respond to sustainability challenges, with implications for corporate strategy, investor assessment of climate disclosures, and regulatory policy design.
