日本語

本研究は、AMCフレームワークを用いて、自然災害が企業のGHG排出原単位に与える影響を、2006年から2020年の米国上場企業854社のデータで分析。災害直後は排出原単位が一時的に増加するが、動機と能力が高い企業やコミュニティでは増加が抑制され、逆転することもある。災害が環境行動を促す条件を特定した。

English

Using the AMC framework, this study analyzes 854 U.S. listed firms (2006-2020) to show that natural disasters initially increase GHG emissions intensity, but firms and communities with high motivation and capability can attenuate or reverse this increase. It identifies conditions under which focusing events translate into environmental action.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では、気候災害の頻発が企業の排出削減努力に影響を与える可能性を示唆。SSBJ開示やTCFD対応において、災害リスクと排出パフォーマンスの関連を考慮する必要性を示す。

In the global GX context

This study contributes to global understanding of how climate disasters affect corporate emissions, relevant for climate risk disclosure under TCFD/ISSB and for investors assessing resilience. It highlights the role of community context in shaping corporate environmental responses.

📄 Abstract（原文）

Drawing on the awareness–motivation–capability (AMC) framework and Durand et al. (2019), this paper examines why natural disasters as potential focusing events relate to firms’ decisions to alter their greenhouse gas (GHG) emissions intensity after a disaster hits the community where their headquarters are located. Focusing on 854 publicly listed U.S. firms from 2006 to 2020, we find an immediate, short-lived increase in GHG emissions intensity following disasters, consistent with temporarily disrupted motivation and degraded capability. However, as expected, we find that firms with higher firm-level motivation and capability to act exhibit a smaller increase in GHG emissions intensity in the years following disasters. Similarly, firms located in communities with stronger pro-environmental community logics (which enhance motivation to act) and greater social and economic capital (which increase their capability to act) show a lower increase in GHG emissions compared to firms in other communities. Critically, at each level (firm and community), when motivation and the capability to respond are both high, the post-disaster increase in GHG emissions intensity is attenuated and may even be reversed. The study extends research on firm responses to natural disasters, integrates perspectives from AMC and community logics, and identifies the conditions under which focusing events can translate into environmental action.
