世界16,000以上の油田・ガス田プロジェクトを対象に、地政学リスクが供給網再編を通じて資源の座礁と上流排出に与える影響を2050年まで定量化。リスク高騰により石油・ガスの地域間貿易の7分の1が中東・ユーラシアからアフリカ・米州へ移り、約7.2Gtの石油と3.3兆m³のガスが座礁、累積上流排出は1.8Gt CO2換算増加する。エネルギー安全保障強化は排出を低リスク基準以下に抑え得る。
English
Using a global field-level dataset of 16,000+ oil and gas projects integrated with the MESSAGEix-GOAT model, this study quantifies how geopolitical risk reshapes supply chains, stranding resources and raising upstream emissions through 2050. One-seventh of interregional trade shifts from the Middle East and Eurasia to Africa and the Americas, stranding ~7.2 Gt of oil and 3.3 tcm of gas while cumulative upstream emissions rise by 1.8 Gt CO2-eq. Enhanced energy security can cut emissions below the low-risk baseline.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は中東依存度が高く、地政学リスクによる供給途絶・価格高騰に脆弱。本論文は調達先多様化やエネルギー安全保障政策の排出影響を評価する枠組みを提供し、GX推進と安定供給の両立を考える上で示唆に富む。
In the global GX context
As global disclosure frameworks (TCFD/ISSB) increasingly demand climate-risk assessment, this paper shows geopolitical risk is a material driver of stranded assets and upstream emissions, urging integration into transition planning and energy security analysis.

📄 Abstract（原文）
Abstract Geopolitical conflicts are increasingly reshaping global oil and gas supply chains, yet their implications for resource utilization, stranded resources, and upstream greenhouse gas (GHG) emissions remain poorly quantified. Here, we develop a global field-level dataset covering 16,000+ oil and gas projects and integrate it with MESSAGEix-GOAT, a long-term production and trade model, to trace risk-driven redistribution of extraction, trade, and emissions through 2050. We find that heightened geopolitical risk diverts one-seventh of interregional oil and gas trade away from vulnerable routes linked to the Middle East and Eurasia toward Africa and the Americas, with domestic supply increasing in major importers. This reallocation strands about 7.2 gigatonnes (Gt) of oil and 3.3 trillion cubic meters of natural gas at the field level while unlocking higher-cost and more carbon-intensive substitutes with greater reliance on offshore resources. Cumulative upstream emissions increase by 1.8 Gt CO2-equiv (ranging from 0.8 to 3.2) by midcentury, while enhanced energy security measures can reduce emissions below the low-risk baseline. Our study underscores the need to incorporate geopolitical factors and induced resource stranding and emissions into both energy system assessment and global warming analysis.
