本研究は、バイオプラスチックを炭素貯蔵建材として評価するライフサイクル分析を行った。PLA、PEF、PPを比較し、PEFとPPのバイオポリマー集成体は運用エネルギーを5-10%削減し、正味ライフサイクル排出量を110-210kg CO2-eq/m2削減する。これはバイオマス炭素貯蔵によるもので、グリッドの脱炭素化が進むにつれ、体化排出の比率が高まり材料選択が重要になる。非分解性バイオポリマーは長期炭素貯蔵に有効である。

This study performs a life cycle assessment of bioplastics (PLA, PEF, PP) as carbon-storing building materials for New York State. Bioplastic assemblies reduce operational energy demand by 5-10% and net life cycle emissions by 110-210 kg CO2-eq/m2, driven by biogenic carbon storage. As grid carbon intensity declines, the embodied-to-operational emissions ratio quadruples, making material selection critical. Non-degradable bioplastics offer scalable long-duration carbon storage for net-zero targets.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の建築分野でも、グリッド脱炭素化に伴い体化排出への注目が高まっている。本論文の手法と知見は、日本の建材選定やLCA実務に応用可能であり、SSBJや有報におけるスコープ3排出対応にも示唆を与える。
In the global GX context
Globally, as grids decarbonize, embodied emissions become the dominant challenge in building decarbonization. This paper provides a rigorous LCA framework for evaluating biogenic carbon storage in building materials, relevant to ISSB/TCFD-aligned disclosure and net-zero strategies.

📄 Abstract（原文）
The rapid decarbonization of energy grid is shifting the climate mitigation burden in built environment from operational to embodied emissions. This paper evaluates the potential of bioplastics, polylactic acid (PLA; degradable), polyethylene furanoate (PEF; non-degradable), and polypropylene (PP; non-degradable) as carbon storing construction materials. Using a cradle-to-grave life cycle assessment for the New York State determined that bioplastics assemblies reduce operational energy demand by 5-10% and lower net life cycle emissions by 110 kg CO2-eq/m2 for PEF and 210 kg CO2-eq/m2 for PP. These savings are driven by biogenic carbon storage, effectively transforming building envelopes into carbon sinks. Remarkably, as grid carbon intensity declines, the embodied-to-operational emissions ratio quadruples (0.5 to 2), isolating material selection as the critical variables. Therefore, integrating non-degradable bioplastics into building infrastructure offers scalable, robust strategy for long-duration carbon storage necessary to meet net zero targets.
