不確実性を考慮した頑健な意思決定フレームワークを用いた気候政策の評価により、期待効用最大化ではなく後悔回避型のアプローチがより積極的な排出削減を促すことを示した。経済・社会の将来経路や気候被害の不確実性が非対称な結果をもたらし、強い対策を正当化する。
English
This paper applies a robust decision-making framework to climate policy evaluation, showing that shifting from expected utility maximization to a regret-averse approach drives more aggressive emissions reductions. Uncertainties about socio-economic trajectories and climate damages create asymmetric consequences that encourage precautionary, stronger mitigation.

日本のGX文脈において
日本の2050年カーボンニュートラル目標やエネルギー基本計画の見直しにおいて、モデルの不確実性をどう扱うかは重要な論点。本論文の頑健な意思決定フレームワークは、日本の気候政策設計に示唆を与える。
In the global GX context
This paper contributes to the global climate policy debate by demonstrating that model uncertainty, often used to justify delayed action, instead supports stronger near-term emissions reductions under a robust decision-making lens. Relevant for national and corporate mitigation strategies.

📄 Abstract（原文）
Evaluating the economic impacts of climate policies is important for designing a response to climate change. One typical approach to assessing mitigation policy options uses integrated climate-economy models to analyze tradeoffs between the costs of reducing greenhouse gas emissions and the benefits of reducing climate damages. However, the uncertainty characterizing these models poses significant challenges for policymakers. We address this difficulty using a robust decision-making framework to evaluate mitigation policy. We show that a shift from a decision framework that maximizes expected outcomes to one that is averse to regret suggests more aggressive emissions reductions. Uncertainties about socioeconomic trajectories and the magnitude and functional form of climate damages create the asymmetric consequences of weak mitigation policy that encourage aggressive emissions reductions and precaution in the face of uncertainty.
