日本語
本研究は、3つの異なる脱炭素政策経路の下で、乗用車、小型商用車、トラック、バスにおけるパワートレイン切り替え（内燃機関→電気自動車）の環境影響と経済性を評価した。静的および動的LCAモデルを用いて2025～2100年の期間を分析し、政策選択が転換の採算時期に与える影響を明らかにしている。
English
This study evaluates the environmental and economic payback of switching powertrains (from internal combustion to electric) for cars, LCVs, trucks, and buses under three decarbonisation policy pathways. Using static and dynamic LCA models covering 2025-2100, it shows how policy choices affect the timing when switching becomes cost-effective.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文は欧州の政策経路を前提としているが、日本の運輸部門脱炭素（次世代自動車戦略）やSSBJのScope3開示におけるEVシフトの採算性評価に示唆を与える。日本の政策立案者や企業が転換時期を判断する上で参考となる。
In the global GX context
This paper provides a rigorous LCA framework for evaluating powertrain transition payback under varying policy stringency, directly relevant to global TCFD/ISSB scenario analysis and transition planning for the automotive sector. The dynamic model (2025-2100) offers a template for corporate climate transition assessments.
👥 読者別の含意
🔬研究者:Provides a methodology for prospective LCA with time-sensitive payback analysis, useful for transport decarbonization modeling.
🏢実務担当者:Helps automotive and logistics companies assess the optimal timing for fleet electrification under different policy scenarios.
🏛政策担当者:Offers insights on how policy pathways (e.g., carbon pricing, subsidies) accelerate the payback period for EV adoption in road transport.
📄 Abstract（原文）
These spreadsheets contain supplementary data to the article "When does switching powertrain pay off? A prospective life cycle assessment of road transport options under three decarbonisation policy pathways". Interactive model: This file contains the model described in Section 3.5. The Static results sheet presents detailed environmental impacts for vehicle production, battery production, and the tank-to-wheel life cycle stage. These results are not time-sensitive and are calculated for the reference year 2025. The Dynamic results sheet presents detailed environmental impacts for the well-to-tank, vehicle maintenance, and end-of-life life cycle stages. These results are time-sensitive and cover the period 2025–2100. Inventory data: This file contains the inventory data used to model the environmental performance of the analysed road transport vehicles. Separate sheets are provided for cars, LCVs, trucks, and buses. Additional sheets include component-specific data, abrasion and tailpipe emissions during the use phase, and end-of-life modelling. The End-of-life (values) sheet also includes tables with the modelled material composition of individual vehicles and components, along with the corresponding treatment scenario ratios..
