本稿は、従来のEROIでは捉えきれない脱炭素化時代のエネルギー評価に対応するため、拡張エクセルギーに基づくエネルギー投資収益率（Ex-EROI）を提案する。熱力学の第一・第二法則を統合し、エネルギー品質とライフサイクル全体の資本・運用・環境コストを考慮する点が特徴である。脱炭素化、環境持続可能性、エネルギーアクセスと affordability を評価する強力なツールとして位置づけられる。
English
This chapter introduces an extended exergy-based energy return on investment (Ex-EROI) framework to address the limitations of conventional EROI in capturing the complexity of the current decarbonization-driven energy transition. It integrates exergy analysis (First and Second Laws) to account for energy quality and applies a life-cycle perspective including capital, operational, and environmental costs. The approach is positioned as a powerful tool for assessing energy transition challenges such as decarbonization, environmental sustainability, and energy accessibility and affordability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策では、エネルギー転換の評価指標として従来のEROIに加え、環境コストやエネルギー品質を考慮した新たな枠組みが求められている。本手法は、日本のエネルギー基本計画やGX実現に向けた投資判断において、より包括的な評価を提供する可能性がある。
In the global GX context
Globally, the framework responds to the need for more comprehensive energy assessment tools beyond EROI, aligning with ISSB and CSRD emphasis on sustainability metrics. It offers a methodological contribution to transition finance by incorporating environmental costs, which could inform investment decisions and policy frameworks.

📄 Abstract（原文）
Usual energy assessment techniques, like the energy return on investment (EROI), are not suitable for capturing the complexity of the current transition that is driven by governments and businesses around the world pursuing decarbonization strategies. A framework that considers the effects of energy production and usage on the environment, as well as energy quality, is needed. Therefore, the extended exergy–based energy return on investment approach is introduced in this chapter. While conventional EROI focuses solely on the ratio of energy output to input, the extended exergy–based method integrates exergy analysis, combining the First and Second Laws of Thermodynamics to account for energy quality, and applies a life-cycle perspective that includes capital, operational, and environmental costs. The approach can be a powerful tool for assessing the current energy transition, where decarbonization, environmental sustainability, and energy accessibility and affordability are key challenges.
