ギリシャのモデルパラメータを用い、BEV・HEV・ガソリン車をcradle-to-graveでLCA比較した研究。機能単位は15万車両キロ、ReCiPe 2016 Endpointで評価。BEVはICEV比で温暖化の健康影響43.2%減、PM2.5形成44.8%減、陸域酸性化45.1%減。HEVは化石・鉱物資源枯渇で51.5%・55.8%減。電動車は効率改善と電力脱炭素の併進が必要と結論。
English
A cradle-to-grave LCA comparing BEVs, HEVs, and gasoline ICEVs using Greek parameters (150,000 vehicle-km, ReCiPe 2016 Endpoint). BEVs cut global-warming health damage by 43.2%, PM2.5 formation by 44.8%, and terrestrial acidification by 45.1% versus ICEVs; HEVs cut fossil and mineral resource scarcity by 51.5% and 55.8%. Results show category-specific trade-offs and support combining vehicle efficiency with electricity decarbonization.

📄 Abstract（原文）
Transport electrification can reduce climate impacts, but its environmental performance depends on vehicle production, energy supply, operation, and end-of-life treatment. This study compares battery electric vehicles (BEVs), non-plug-in gasoline hybrid electric vehicles (HEVs), and gasoline internal combustion engine vehicles (ICEVs) using model parameters relevant to Greece. A cradle-to-grave life cycle assessment was implemented in openLCA using ReCiPe 2016 Endpoint (H), with a functional unit of 150,000 vehicle-kilometres. Both electrified configurations exhibited lower impacts than the ICEV across all 18 indicators with positive results. The BEV achieved reductions of 43.2% in global-warming damage to human health, 44.8% in fine particulate matter formation, and 45.1% in terrestrial acidification relative to the ICEV. The HEV achieved reductions of 51.5% and 55.8% in fossil and mineral resource scarcity, respectively. Each electrified technology recorded the lowest value in nine positive indicators. The BEV–HEV ranking-margin analysis identified equal-impact thresholds of 9.05% for global-warming damage to human health and 4.25% for human carcinogenic toxicity. Negative water-consumption indicators were retained without interpretation as physical water savings. The findings identify category-specific trade-offs and support coordinated vehicle-efficiency and electricity-decarbonization measures without establishing overall environmental superiority.
