本研究は、ベルギーの建設部門におけるバイオベース材料の環境影響をライフサイクルアセスメント（LCA）を用いて評価した。従来の材料と比較した結果、気候変動への影響は低減できるものの、土地利用などの他の影響が増加する可能性があり、明確な優位性は見られなかった。ホットスポット分析により、バイオベース材料の生産段階での低影響と、バイオジェニックカーボンの取り込み・放出による廃棄段階での高影響が明らかになった。
English
This study assesses the environmental impact of bio-based construction materials in Belgium using LCA. Comparing with conventional materials, it finds that bio-based materials can reduce climate change impacts but may increase other impacts like land use, with no clear overall advantage. Hotspot analysis reveals lower production impacts but higher end-of-life impacts due to biogenic carbon dynamics.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
ベルギー国内の建設用材料に特化した研究であり、日本のGX文脈では直接の適用は難しい。しかし、バイオベース材料の環境影響評価手法やトレードオフの理解は、日本の建設業界のカーボンニュートラル戦略に示唆を与える可能性がある。
In the global GX context
While Belgium-specific, this paper offers a rigorous LCA framework for evaluating bio-based materials, highlighting trade-offs between carbon reduction and other environmental impacts. Useful for global construction decarbonization efforts, but note the context differs from Japan's building codes and material markets.
👥 読者別の含意
🔬研究者:Provides a detailed LCA comparison and hotspot analysis for bio-based materials, useful for further research on environmental trade-offs.

🏛政策担当者:Demonstrates the need for multi-indicator assessment to avoid burden shifting when promoting bio-based materials in building regulations.
📄 Abstract（原文）
Abstract In the building sector, the use of bio-based materials has gained increased attention to reduce the embodied CO 2 emissions of buildings. This paper aims at assessing the potential environmental benefits of using bio-based materials in the Belgian building sector. A selection of representative bio-based materials is assessed based on life cycle assessment (LCA), using the Belgian LCA tool TOTEM. These materials are compared against conventional, non-bio-based alternatives. The assessment is done at different scale levels, ranging from individual building components (e.g. structural layers, insulation and finishes) to complete building elements (i.e. external walls specifically). To avoid burden shifting, the assessment is not limited to the climate change indicator solely but includes an aggregated environmental score, derived from the set of indicators recommended by the EN 15804+A2 standard. The results are analysed in two steps: first, by comparing the aggregated environmental scores of the different variants; second, by identifying environmental hotspots in terms of impact indicators and life cycle stages. The comparison between the bio-based and conventional alternatives does not reveal a clear preference between the two. The hotspot analysis highlights the potential of bio-based materials to reduce climate change impacts. However, this impact reduction is frequently offset by an increase in other impact categories, such as land use. Additionally, while bio-based materials generally exhibit lower impacts during the production phase, they tend to have higher end-of-life impacts due to the uptake and release of biogenic carbon.
