日本語
メキシコの電力システムをライフサイクル評価と資源分析で評価し、EI99H損害結果から4つのエネルギー持続可能性指標を新たに開発した。2013〜2023年で燃料油・水・バイオマスは改善したが、天然ガスと石炭の影響は増大。人間健康への損害は生態系品質より55%高く、主因は化石燃料燃焼である。
English
This study assesses Mexico's electricity system via life-cycle assessment and resource analysis, introducing four novel energy sustainability indices derived from EI99H damage results. Fuel oil, water, and biomass improved from 2013–2023, while natural gas and coal impacts rose. Human health damage exceeds ecosystem quality by 55%, driven by fossil fuel combustion.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では電源構成の脱炭素評価やLCA指標の設計に関心が高く、SSBJ・有報でのScope 3や電力調達の開示を検討する企業にとって、指標設計の参考になる。ただしメキシコ固有の政策文脈が中心で、直接の日本制度接続は限定的。
In the global GX context
Adds a non-OECD, fossil-heavy electricity case to the global transition literature, complementing TCFD/ISSB-aligned power-sector decarbonization assessments. The proposed indices offer a replicable framework for comparing national grids beyond direct carbon emissions, relevant to CSRD and transition-finance analyses.
👥 読者別の含意
🔬研究者:電力システムのLCAと持続可能性指標設計の新手法として、国別比較研究に応用可能。
🏢実務担当者:電力調達やScope 2/3評価において、炭素以外の環境負荷指標を検討する際の参考になる。
🏛政策担当者:電源構成の脱炭素政策評価に、健康・生態系影響を含む多面的指標の必要性を示唆。
📄 Abstract（原文）
The global energy transition is driving power systems toward lower-carbon electricity generation, requiring sustainability assessments that consider environmental burdens beyond direct carbon emissions. This study evaluates Mexico’s electricity system using life cycle assessment, resource analysis, and energy sustainability indices. The main novelty of this study is the development of four energy sustainability indices derived from EI99H damage results: the Index of Environmental Change per Energy Unit, Relative Environmental Change Index, Per Capita Environmental Impact, and Environmental Intensity Metric. These indices capture temporal environmental change, generation-related variation, population-related burden, and environmental impact per unit of electricity. Results show improvements in fuel oil, water, and biomass performance between 2013 and 2023, whereas natural gas and coal impacts increased. Mexico exhibits a lower per capita environmental burden than Germany and Spain, while France shows the lowest value, largely due to its nuclear-based electricity mix. Human Health damage is 55% higher than Ecosystem Quality, mainly due to fossil fuel combustion. Hydroelectric generation shows substantial water demand, while solar and wind have negligible requirements. Rising natural gas costs constrain competitiveness, whereas renewables maintain low operating costs.
