本研究は、十分性（sufficiency）介入の社会的共便益を実証的に評価するための多段階・反復的な方法論を提示する。Inferences-to-the-Best-Explanation、チェンジ・オブ・セオリー、ベイズ認識論、因果ダイアグラムを組み合わせ、公共交通改善を事例に健康共便益への経路を分析する。汚染削減と身体活動増加による健康便益は信頼性が高い一方、自動車から公共交通へのモーダルシフト自体は自明ではなく、利用者の選好と能力に強く左右されると示す。因果ダイアグラムにより直接効果と間接効果を区別し、実証研究で統制すべき変数を特定できる。
English
This paper presents a multi-staged, iterative methodology for empirically assessing the social co-benefits of sufficiency interventions, combining Inferences-to-the-Best-Explanation, Theory-of-Change, Bayesian epistemology, and causal diagrams. Using public transport improvement as a case study, it identifies two health co-benefit pathways: reduced pollution and increased physical activity. Bayesian assessment shows health benefits are credible, but the initial modal shift from cars is heavily moderated by user preferences and capabilities. The framework distinguishes direct from indirect effects and is adaptable to sustainable finance and scenario analysis.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では十分性（sufficiency）は省エネ・脱炭素政策の周辺概念にとどまり、SSBJや有報の開示実務との直接接点は薄い。ただし、シナリオ分析やインパクト評価の因果設計に関心を持つ国内企業・自治体にとって、政策効果の誤謬を避ける枠組みとして参考になる。
In the global GX context
Globally, this contributes to impact assessment and transition-planning methodology by offering a causal-inference blueprint for co-benefits, which is relevant to ISSB/CSRD-adjacent scenario analysis and sustainable-finance impact models. It bridges qualitative case research and quantitative population evaluation, a gap increasingly noted in climate-policy and disclosure scholarship.

📄 Abstract（原文）
Abstract Background Sufficiency is a critical but often overlooked decarbonization strategy. A significant challenge in promoting sufficiency is the difficulty in assessing its social co-benefits, such as improved health outcomes. This study presents a multistaged, iterative methodology designed to facilitate empirical investigations into the direct and indirect causal effects of sufficiency interventions. The primary purpose is to bridge the gap between an ex-ante impact hypothesis, potential impact models and evidence for plausible causal pathways. It helps to identify relevant variables and guides their statistical control. Results The methodology employs a four-step heuristic approach combining Inferences-to-the-Best-Explanation logic, Theory-of-Change models, Bayesian epistemology, and causal diagrams. Using the improvement of public transport systems as a case study, the methodology identifies two main pathways to health co-benefits: the reduction of pollutants leading to cleaner air and the increase in physical activity from walking or cycling to transit points. Bayesian credence assessments reveal that while the health benefits from reduced pollution and increased activity are highly credible, the initial “modal shift” from cars to public transport is not a trivial outcome. The results highlight that this shift is heavily moderated by the specific preferences and capabilities of car users. Causal diagrams further enable the distinction between direct and indirect effects, allowing researchers to identify which parameters must be controlled for in empirical studies to accurately predict health outcomes. Conclusions The proposed methodology provides a robust blueprint for establishing plausible impact relations in social impact assessments. It successfully closes the gap between qualitative case-oriented research and quantitative population-oriented evaluations. It follows a probabilistic epistemology and is thus open to different types of impact assessment methods, including both impact modelling and conventional statistics. By re-evaluation of pathways in light of evidence, the approach helps researchers avoid causal fallacies and biased expectations. Beyond transport, this iterative framework is adaptable to various sectors, including sustainable finance and scenario analysis, offering a versatile tool for designing more effective decarbonization policies and impact models.
