本研究は、熱力学の法則を世界のエネルギー転換分析に統合し、後発国のジレンマを「エントロピー債務」の概念で捉える。位相空間モデルを用いて歴史的排出による「不正義ギャップ」を特定し、再生可能エネルギー中心の循環経済がエントロピートラップに陥ることを示す。解決策として、遡及的なETS3メカニズムで資金調達する第4世代原子炉を提案し、エネルギー正義が物理的必要条件であると論じる。マンチェスターの放射債務を約1428億ユーロと定量化する。

English

This study integrates thermodynamic laws into global energy transition analysis, framing the latecomer's dilemma as 'entropy debt.' Using a phase space model, it identifies an 'injustice gap' foreclosed by historical emissions and argues that a circular economy powered by low-density renewables becomes an entropy trap. It proposes Generation IV nuclear reactors funded by a retroactive ETS3 mechanism as a stabilization solution, quantifying Manchester's radiative debt at ~€142.8 billion. The work synthesizes biophysical constraints with energy justice.

日本のGX文脈において

日本のGX政策（GX推進戦略、原子力活用、カーボンプライシング導入）に理論的裏付けを与える。特に、後発国支援や国際的なカーボンプライシング設計（ETS3）の議論に示唆を与え、日本のエネルギー政策における原子力の位置づけを再考する材料となる。

In the global GX context

This paper contributes to global debates on climate justice and transition finance by introducing a thermodynamic perspective on historical emissions. It challenges the feasibility of renewable-only circular economies and proposes a retroactive carbon pricing mechanism (ETS3) to fund high-density energy solutions, relevant to ISSB/CSRD discussions on just transition and climate risk.

👥 読者別の含意

🔬研究者:Provides a novel theoretical framework linking thermodynamics, ecological debt, and energy justice, useful for scholars modeling transition pathways.

🏢実務担当者:Offers conceptual justification for nuclear investments and carbon pricing mechanisms, though practical implementation details are limited.

🏛政策担当者:Highlights the need for retroactive carbon pricing and support for latecomer nations, informing international climate policy design.

📄 Abstract（原文）

When the global energy transition is analyzed through economic lenses, the constraints imposed by the laws of thermodynamics are often overlooked. This study addresses the Latecomer’s Dilemma—the predicament of semi-peripheral nations compelled to decarbonize without the capital stock accumulated following the example of the countries of the Global North during their more than two hundred years of industrial development associated with the saturation of the atmosphere with carbon dioxide. A novel phase space model of the Anthropocene is constructed, synthesizing the political concept of ecological debt with the biophysical reality of entropy debt. The application of the laws of systems ecology and non-equilibrium thermodynamics enables the mapping of national development trajectories against the saturated “atmospheric bathtub”. The analysis identifies a critical Injustice Gap—a region of phase space physically foreclosed by historical emissions. Moreover, it has been demonstrated that a circular economy powered by low-density renewables functions as an entropy trap, converting material debt into radiative debt without achieving a closed loop. Consequently, the Polish correction vector is proposed as a stabilization mechanism. This study’s findings indicate that addressing the emerging phenomenon of adaptation apartheid necessitates the implementation of a high-density energy flux, namely Generation IV nuclear reactors, which would be funded by a retroactive ETS3 mechanism. This approach fulfills the thermodynamic condition for material closure, thereby substantiating the notion that energy justice constitutes a physical necessity for planetary stability. This study quantifies the historical radiative debt of a single early-industrialized hub (Manchester) at approximately 142.8 billion EUR. The novelty lies in the synthesis of biophysical laws and the Latecomer’s Dilemma through the proposed ETS3 mechanism.
