日本語

21カ国を対象に気候不安の prevalence と予測因子を調査。気候意識と思考頻度が不安と正の関連を示すが効果量は小さい。コストや情報不足が気候行動の主な障壁であり、不安軽減には意識向上だけでなく行動を可能にする条件整備が必要。

English

This multi-country survey of 21 countries examines climate anxiety, finding over 60% feel emotionally overwhelmed. Climate awareness and thinking frequency are positively associated with anxiety but with small effect sizes. Barriers such as cost and lack of information hinder climate action, suggesting that reducing anxiety requires enabling conditions beyond awareness.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本のGX文脈では、気候不安が行動変容に与える影響は注目されるが、本調査は日本固有データを含まず、SSBJや有報への直接示唆は限定的。ただし、企業の気候関連リスク認識や従業員エンゲージメントに応用可能性がある。

In the global GX context

While not directly addressing disclosure or transition finance, this study highlights psychological barriers to climate action, relevant for global GX stakeholders designing behavior change interventions or communicating climate risks to stakeholders.

👥 読者別の含意

🔬研究者:Provides cross-country evidence on climate anxiety levels and its weak link to pro-environmental behaviors, highlighting research gaps on structural barriers.

🏢実務担当者:Suggests that merely raising climate awareness may not drive action; practitioners need to address cost, availability, and information gaps to foster behavior change.

🏛政策担当者:Indicates that enabling conditions (e.g., subsidies, infrastructure) are crucial to translate climate concern into action, complementing awareness campaigns.

📄 Abstract(原文)

Climate change is increasingly recognized as a source of psychological distress, yet the prevalence, predictors, and behavioral implications of climate anxiety remain unevenly understood. This study examines climate anxiety, its key drivers, and associated behavioral responses in a multi-country sample of adults. A cross-sectional online survey was conducted across 21 countries using the Climate Change Anxiety Scale (CCAS), alongside measures of awareness, coping strategies, social support, and food-related behaviors, including food waste reduction, increased plant-based food consumption, and home or community gardening. Analyses included descriptive statistics, exploratory factor analysis (EFA), and multivariable regression. Given the uneven country-level representation, results are reported as pooled patterns with a few exploratory cross-country comparisons. Climate anxiety was widely reported, with over 60% of participants indicating that climate challenges were emotionally overwhelming. Regression analyses showed that climate awareness and frequency of climate-related thinking were positively associated with higher anxiety, although the effect sizes were small and explanatory power was limited (R2 = 0.055). EFA identified two related dimensions: cognitive concern about future impacts and affective distress. Climate anxiety across countries showed modest variation (2.44–3.23) and no statistically significant differences, despite variation in awareness. A gap between concern and climate action was evident: only 39.1% reported environmentally motivated dietary changes. Cost, limited availability, and lack of information were the main barriers to climate action, and only 24.4% reported frequent social support. These findings indicate that climate anxiety is shaped by both psychological and structural factors, and that reducing it requires not only increasing awareness but also enabling conditions that support meaningful climate action.
