再生可能エネルギーへの移行は、資源の利用可能性、エネルギー収支比(EROI)、材料サプライチェーンに制約される。本研究は、迅速な脱炭素化と公平な成果の間の緊張を検討し、2050年までにクリティカルミネラルの需要が電力部門で200-900%、運輸部門で350-700%増加する可能性を示す。移行中の利用可能な正味エネルギーは10-34%減少し、エネルギー貧困国が最も影響を受ける。技術モデルでは公平性の側面が見落とされがちで、マルチステークホルダー協力や修復的公正、脱成長戦略が提案されている。政策設計が慎重でなければ、エネルギー転換は世界的不平等を強化する可能性がある。
English
The transition to renewable energy is constrained by resource availability, energy return on investment (EROI), and material supply chains. This study examines the tension between rapid decarbonisation and equitable outcomes, projecting that demand for critical minerals could increase by 200–900% in electricity and 350–700% in transport by 2050. Net energy available may decline by 10–34%, with energy-poor countries most affected. Equity considerations are often overlooked in technical models. The study highlights multi-stakeholder cooperation, restorative justice, and degrowth strategies as potential solutions, warning that without careful policy design the transition may reinforce global inequalities.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
この論文は、日本がエネルギー転換を進める上で、資源制約と公平性のバランスを考慮する重要性を示している。日本はクリティカルミネラルの多くを輸入に依存しており、グリーン成長戦略におけるサプライチェーンリスクの認識と、公正な移行(just transition)の視点が求められる。エネルギー貧困や地域間格差への対応は、日本の地方創生やエネルギー自給率向上にも関連する。
In the global GX context
This paper offers a critical perspective on the global energy transition by highlighting the physical constraints of resource availability and the equity implications. It is relevant for ISSB/TCFD frameworks that increasingly consider just transition and supply chain resilience. The findings underscore the need for transition finance and policy mechanisms that address both decarbonization and distributional impacts, especially for developing countries.
👥 読者別の含意
🔬研究者:Researchers should note the empirical projections on critical mineral demand and net energy decline, and the call to integrate equity into energy system models.
🏢実務担当者:Corporate sustainability teams can use the analysis on material supply chain risks and the equity dimension to inform their ESG and just transition strategies.
🏛政策担当者:Policymakers should consider the implications for critical mineral security, just transition policies, and international cooperation to avoid exacerbating inequalities.
📄 Abstract(原文)
The transition to renewable energy is constrained by resource availability, energy return on investment (EROI), and material supply chains. This study examines the tension between rapid decarbonisation and equitable outcomes. Results indicate that demand for critical minerals in renewable technologies could increase total material use by 200–900% in the electricity sector and 350–700% in transport by 2050. Net energy available during the transition may decline by 10–34%, with energy-poor countries mostaffected. Equity considerations, such as distribution, process, and recognition, are often overlooked in technical models. The study identifies multi-stakeholder cooperation, restorative justice, and degrowth strategies as potential solutions. Without careful policy design, the energy transition may reinforce existing global inequalities.
