この論文は、2050年までのネットゼロ炭素目標達成に向けて、建築環境におけるライフサイクルアセスメント（LCA）の基準をレビューしている。建築物の長寿命や製品カテゴリルールの必要性など、全ライフサイクル炭素評価の課題を特定し、基準の調和を提案する。建設部門の脱炭素化に重要な示唆を与える。
English
This paper reviews current standards for life cycle assessment (LCA) in the built environment to support net-zero carbon goals. It identifies gaps such as the need for harmonized Product Category Rules and Environmental Product Declarations, and challenges from long building service lives. The review emphasizes that addressing these is critical for decarbonizing the construction sector, which has high transformative potential.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の建設業界では、国土交通省の建築物省エネ法やゼロエネルギー建築（ZEH）の推進があり、本レビューのLCA基準調和の議論は、日本版規格（JIS）や業界標準への応用が期待される。特に、SSBJの情報開示基準とも関連し、サプライチェーン排出量の算定にも影響する。
In the global GX context
Globally, this review aligns with the ISSB's emphasis on Scope 3 emissions and the EU's Level(s) framework for sustainable buildings. It highlights the need for consistent carbon accounting standards across jurisdictions to enable transition finance and green building certification like LEED or BREEAM.
👥 読者別の含意
🔬研究者:This paper provides a structured overview of LCA standards and gaps, useful for researchers working on building lifecycle carbon assessment methods.
🏢実務担当者:Corporate sustainability teams in construction and real estate can use this to understand the standards landscape and anticipate harmonization trends for reporting.

📄 Abstract（原文）
Net-zero carbon by 2050 is a key goal of the Paris Agreement. To achieve this in the built environment, we must analyze the building life cycle to find ways to reduce or offset contributions to climate change associated with materials, maintenance, and end-of-life activities. Using holistic assessment techniques such as Life Cycle Assessment (LCA) is essential for this process. While environmental evaluation standards for LCA exist, modifications may be needed to support the design and assessment of net-zero carbon buildings. This paper reviews current standards for construction products and buildings, identifies gaps, and explores opportunities for harmonization. ISO and other standards provide a solid foundation for structuring LCAs for the building lifecycle. The review finds that implementing whole-life carbon faces challenges such as the long service life of buildings, the need for relevant Product Category Rules (PCRs) and Environmental Product Declarations (EPDs), and the harmonization of standards. Addressing these challenges is essential for decarbonizing the construction sector, which has a significant impact as well as potential for transformative change in mitigating climate change.
