米国で独自のサーベイ実験を行い、気候脆弱性に関する情報が適応策と緩和策への選好をどう変えるかを検証した。脆弱性を認識していない層は情報提示後に緩和より地域適応を優先する一方、強い事前信念を持つ層は反応しなかった。無党派層で効果が特に一貫しており、緩和と適応が財源を争う状況で緩和支持の動員が難しいことを示す。
English
Original US survey experiments test how information about climate vulnerability shifts preferences between adaptation and mitigation. Those with weak priors prioritize local adaptation over mitigation when informed of their vulnerability, while those with strong priors remain unmoved. Effects are most consistent among independents, highlighting a challenge for mobilizing mitigation support when the two compete for funding.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
気候リスク情報の伝達が有権者の政策優先順位を変えうることを示し、日本での適応計画と緩和策の予算配分や気候リスク開示のコミュニケーション設計を考える上で示唆がある。
In the global GX context
Relevant to global disclosure scholarship on how climate-risk information is framed and consumed: it shows that vulnerability messaging can crowd out mitigation support, informing how TCFD/ISSB-aligned risk communication and adaptation finance narratives are designed.
👥 読者別の含意
🔬研究者:気候リスク情報が適応と緩和の選好トレードオフに与える因果効果を、事前信念の強さで条件付けて示す実証研究として参照できる。
🏢実務担当者:気候リスク開示や適応策の対外コミュニケーションが、緩和策への支持を損なわないよう配慮する必要性を示す。
🏛政策担当者:適応と緩和が財源を争う局面で、脆弱性情報の発信が緩和支持の動員を弱めうる点を政策設計に織り込むべき。
📄 Abstract（原文）
Abstract Climate change is significantly increasing the frequency and severity of extreme weather events. Prior research indicates that exposure to such events can make individuals more supportive of green policies. But we know less about how this shapes individuals’ priorities across policies. Given that governments are budget constrained, policymakers may confront a trade-off between climate policy goals. We conducted original survey experiments in the United States to understand how information about climate vulnerability shapes preferences for adaptation and mitigation, particularly when voters are forced to choose between the two. We find that when individuals with weak priors are told about their vulnerability to extreme weather events, they prioritize local adaptation relative to mitigation, while those with stronger priors remain largely unmoved. Effects are especially consistent among independents, a crucial voting bloc as climate change becomes polarized. These findings underscore a potential challenge of mobilizing support for mitigation in cases in which mitigation and adaptation compete for funding.
