日本語
本論文は、ポーランドの教育施設を事例に、CLT（直交集成板）とコンクリート技術のライフサイクル評価（LCA）比較を行った。気候変動と都市化の影響下で、持続可能な建材としての木材の優位性を評価し、CLTが低炭素で環境負荷の低い選択肢であることを示した。EU規制の強化に伴い、環境配慮型材料への需要が高まる中、本分析は建設業界の脱炭素化に貢献する。
English
This paper presents a comparative life cycle assessment (LCA) of cross-laminated timber (CLT) and concrete for an educational building in Poland. It demonstrates that CLT has a lower carbon footprint and environmental impact, highlighting wood's potential as a sustainable construction material. The study aligns with tightening EU regulations and growing demand for low-carbon materials.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも木造建築推進政策（CLT活用促進など）が進んでおり、本論文のLCA手法と実証結果は、日本の建設業界における木造化・低炭素化の意思決定に参考となる。ただし、対象地域の気候・規制が異なるため、直接適用には調整が必要。
In the global GX context
This case study from Poland provides empirical LCA data comparing CLT and concrete, relevant to global efforts to decarbonize construction under EU regulations. It offers a methodological template for similar assessments in other regions, including Japan, where CLT adoption is growing.
👥 読者別の含意
🔬研究者:Provides a detailed LCA comparison of CLT vs concrete for a real building, useful for building material sustainability research.

📄 Abstract（原文）
During the second decade of the 21st century, the effects of climate change became particularly noticeable, as population growth and aggressive urbanisation degraded the natural environment. In modern construction industry, the concepts of sustainable development and life cycle assessment (LCA) are important, covering the investment process from design and construction to operation and potential demolition. Wood, a natural raw material present in architecture for centuries, unites the ecological, economic and social principles of sustainable design. Thanks to innovative processing techniques such as cross-laminated timber (CLT) technology, wood can meet the challenges of modernity. Given the growing consumer interest in pro-environmental attitudes and the tightening of regulations within the European Union, the main emphasis will likely be on choosing environmentally friendly materials with a low carbon footprint, favourable energy balance, and ultimately, recovery or reuse potential. Based on this hypothesis, the paper presents a comparative LCA analysis of CLT and concrete technology for the implementation in an educational building at the Forest Botanical Garden Marszewo in Gdynia.
