エネルギー転換モデルは客観的・価値中立と見なされがちだが、実は正義に関わる前提を内包する。本研究はオランダの2つの政策用モデル(Energy Transition ModelとHestia)の開発者・利用者とのワークショップを通じ、省察手法を開発・検証した。モデルのスコープ設定、規範的仮定、政策誘導効果、誤り、複雑性、誤用という6類型の(不)正義の顕在化を提示し、設計者と利用者の間で責任が転嫁され続ける「責任ギャップ」を指摘する。

English

Energy models are often treated as objective, yet they embed justice-relevant assumptions. Through two workshops with developers and users of two Dutch policy models (Energy Transition Model, Hestia), the authors develop and test a reflection method. They propose a six-part typology of how (in)justice manifests in/via models—scoping, normative assumptions, policy steering, errors, complexity, misuse—and identify a persistent 'responsibility gap' between modellers and users.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では第7次エネルギー基本計画やGX推進戦略など、モデル分析に基づく政策決定が進む。モデルの価値前提やステークホルダー認識を問う本稿の視点は、日本の政策モデルガバナンスや統合報告における意思決定プロセスの透明性議論に示唆を与える。

In the global GX context

As ISSB/TCFD disclosure pushes companies and governments toward transparent, defensible transition planning, this paper highlights that the models underpinning transition scenarios carry hidden normative choices. It adds a justice-and-reflexivity lens to global debates on scenario credibility and accountability in climate policy.

📄 Abstract(原文)

Energy models play a central role in energy transition decisions yet are often treated as objective and value-neutral tools. Increasingly, scholars and practitioners argue that energy justice should be more explicitly linked to energy modelling, both because of its intrinsic importance and in response to contestation of top-down, techno-economic decision-making. Existing efforts largely focus on incorporating justice within model logic, for example through equity metrics or participatory modelling. However, these approaches themselves embed often-implicit assumptions about justice, including who is recognized as a stakeholder, whose knowledge is represented, and which interests are prioritized. Because such choices carry justice implications, it is essential that model developers and users engage reflexively with the modelling process. Yet, few concrete tools exist to support such reflection. This paper asks: How, and to what extent, does a reflection method help model developers and users identify assumptions and choices with potential justice implications? We develop and test a reflection method in two workshops with developers and users of two policyrelevant energy models in the Netherlands: Energy Transition Model and Hestia. Our findings show how structured reflection can surface justice-relevant assumptions across the modelling process. We propose a typology of six ways in which (in)justice can manifest in/via energy models: model scoping, normative assumptions, policy steering effects, errors, complexity, and potential misuse. We identify a persistent "responsibility gap" between modellers and users, whereby responsibility for justice consequences is continually shifted between those who design models and those who apply them. We conclude with implications for integrating reflexivity and justice awareness into energy modelling practice.
