ISO 14040/14044準拠のLCAで、太陽光発電・EV・グリーン建材の3分野におけるグリーン技術イノベーションの環境便益を定量化。結晶シリコンPVはGWPを38.6%削減、リチウムイオン電池リサイクルはEVのライフサイクル炭素強度を22.4%低減、産業副産物活用建材は埋め込み炭素を31.2%削減。感度分析とモンテカルロで頑健性を確認し、カーボンニュートラル政策への実証的根拠を提示する。
English
Using an ISO 14040/14044-aligned LCA framework, this study quantifies environmental benefits of green technology innovation across PV energy, EVs, and green building materials. Crystalline silicon PV cuts GWP by 38.6%, Li-ion battery recycling lowers EV life-cycle carbon intensity by 22.4%, and byproduct-based building materials reduce embodied carbon by 31.2%. Sensitivity analysis and Monte Carlo simulation confirm robustness, offering empirical support for carbon-neutrality policy.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ基準や有報でのScope3・製品ライフサイクル開示が進む中、LCAに基づく削減効果の定量エビデンスは、企業の移行計画や統合報告書の説得力を高める材料となる。特にPV・EV・建材は国内製造業のGX投資判断と親和性が高い。
In the global GX context
As ISSB/CSRD and TCFD-aligned disclosure increasingly demand product-level life-cycle data, this paper provides sector-specific LCA evidence that can feed into transition plans and Scope 3 accounting. It reinforces the quantitative basis for green technology deployment claims in global climate disclosure.

📄 Abstract（原文）
By now, green technology innovation (GTI) is broadly acknowledged as a key route for reaching sustainable development goals. At the same time, there is still a lack of systematic quantification of the environmental benefits that GTI delivers across varied industrial sectors. We use a life cycle assessment (LCA) framework aligned with ISO 14040 and ISO 14044 standards to evaluate how GTI performs environmentally in three representative sectors: photovoltaic (PV) energy systems, electric vehicles (EVs) and green building materials. A cradle-to-grave boundary is adopted, and we quantify midpoint impact categories including global warming potential (GWP), acidification potential (AP), eutrophication potential (EP) and cumulative energy demand (CED). A 38.6% reduction in the GWP of crystalline silicon PV modules relative to conventional power generation emerges from the results, and lithium-ion battery recycling technologies are found to lower the life cycle carbon intensity of EVs by 22.4%. Green building materials that incorporate industrial byproducts give a 31.2% reduction in embodied carbon compared with traditional Portland cement. These findings are found to be robust when considering parameter uncertainty, as shown by sensitivity analysis and Monte Carlo simulation. Empirical evidence supporting policy frameworks that encourage GTI deployment toward carbon neutrality targets is provided by these results.
