本研究は、人間の緩和行動と環境フィードバックを組み込んだ社会気候モデルを分析。同質性（homophily）が初期環境状態が悪い場合に壊滅的結果を防ぐ可能性を示し、富裕層の「通常営業」戦略からの貧困層の離脱が植生消失を回避することを発見。単純化されたモデルだが、意思決定の社会的ダイナミクスへの洞察を提供。
English
This study analyzes coupled social-climate models incorporating human mitigation behavior and environmental feedback. It finds that homophily can prevent catastrophic outcomes when the initial environmental state is poor, and that defection of poorer groups from the 'business as usual' strategy of richer groups can prevent vegetation collapse. While based on simplified models, it offers insights into social dynamics of decision-making in environmental sustainability.

日本のGX文脈において
日本のGX政策（例：GX実現に向けた基本方針）では、社会行動変容のメカニズム理解が重要だが、本モデルは抽象度が高く、具体的な政策設計への応用にはさらなる研究が必要。
In the global GX context
This paper contributes to global GX discourse by modeling how social dynamics like homophily and inequality affect mitigation outcomes, relevant to understanding collective action in climate policy. However, its simplified assumptions limit direct applicability to real-world policy design.

📄 Abstract（原文）
Abstract Understanding the role of human behavior in shaping environmental outcomes is crucial for addressing global challenges such as climate change. Environmental systems are influenced not only by natural factors like temperature, but also by human decisions regarding mitigation efforts, which are often based on forecasts or predictions about future environmental conditions. Over time, different outcomes can emerge, including scenarios where the environment deteriorates despite efforts to mitigate, or where successful mitigation leads to environmental resilience. Additionally, fluctuations in the level of human participation in mitigation can occur, reflecting shifts in collective behavior. In this study, we consider a variety of human mitigation decisions, in addition to the feedback loop that is created by changes in human behavior because of environmental changes. While these outcomes are based on simplified models, they offer important insights into the dynamics of human decision-making and the factors that influence effective action in the context of environmental sustainability. This study aims to examine key social dynamics influencing society’s response to a worsening climate. While others conclude that homophily prompts greater warming unconditionally, this model finds that homophily can prevent catastrophic effects given a poor initial environmental state. Assuming that poor countries have the resources to do so, a consensus in that class group to defect from the strategy of the rich group (who are generally incentivized to continue ‘business as usual’) can frequently prevent the vegetation proportion from converging to 0.
