本レビューは、環境クズネッツ曲線（EKC）フレームワークにおけるエネルギー価格の環境影響を、計量書誌学とナラティブ統合により分析した。1997〜2025年の67件の文献を分析し、再生可能エネルギーへの移行が主要テーマであることを示した。実証統合では、エネルギー輸入先進国でEKC仮説と高価格の環境便益が支持される一方、エネルギー輸出国ではN字型EKCや悪影響が報告されることを明らかにした。
English
This review analyzes the environmental impact of energy prices within the EKC framework using bibliometric analysis and narrative synthesis of 67 studies from 1997-2025. It finds renewable energy transition as a dominant theme. Empirical synthesis shows EKC hypothesis and environmental benefits of high prices are more often validated in energy-importing advanced economies, while energy-exporting economies often show N-shaped EKC or adverse effects.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はエネルギー輸入国であり、エネルギー価格上昇が排出削減に寄与する可能性を示す本レビューの知見は、日本の気候政策やエネルギー政策に示唆を与える。特に、再生可能エネルギーへの移行が進む中で、価格メカニズムの役割を理解する上で有用。
In the global GX context
This review provides a global perspective on how energy prices affect emissions, relevant to international climate policy discussions. It highlights the differential impacts in energy-importing vs. exporting economies, which can inform policy design in the context of carbon pricing and energy transition.

📄 Abstract（原文）
Type of the article: Review ArticleAbstractEnergy prices are a crucial factor influencing the emissions–income nexus. Hence, this study aims to examine the environmental effects of energy prices within the Environmental Kuznets Curve (EKC) framework through bibliometric analysis and narrative synthesis of empirical studies. For this purpose, 67 Scopus-indexed documents published during 1997–2025 are analyzed. The bibliometric findings reveal that publications have grown at an exponential rate since 2016, peaking at 10 articles in 2023. Bradford’s Law analysis identifies that Environmental Science and Pollution Research is the leading source. Moreover, Lotka’s Law shows that nearly 75% of authors contributed only one or two studies, indicating a diverse research community. Citation analysis further reveals high global citations but limited local citations, suggesting strong external visibility but relatively weak internal connectivity. Thematic analysis identifies carbon dioxide emissions and renewable energy as dominant motor themes, showing increasing scholarly interest in the renewable energy transition due to high energy prices. The empirical synthesis shows that the EKC hypothesis and environmental benefits of high prices are more frequently validated in energy-importing advanced economies. In contrast, studies on energy-exporting economies often fail to validate the EKC hypothesis or report N-shaped EKC patterns, together with adverse environmental effects of energy prices. Overall, the review concludes that the environmental impact of energy prices within the EKC framework varies according to economic development and energy-trade status.AcknowledgmentThe authors extend their appreciation to Prince Sattam bin Abdulaziz University for funding this research work through the project number (PSAU/2025/RV/9).
