本論文は、英国の住宅建設における材料廃棄物の削減がコストと embodied carbon の削減に与える影響を実証的に分析した。3つの住宅開発プロジェクトと1戸の住宅を対象とした事例研究により、見積もりと実際の使用量の乖離を特定し、国家規模での節約可能性を示した。
English
This empirical study examines opportunities to reduce material waste in UK housebuilding, quantifying cost and embodied carbon savings through improved estimating and procurement. Using mixed methods including three development analyses and a controlled case study, it identifies marginal gains that collectively offer significant financial and carbon reductions when scaled nationally.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも住宅建設における廃棄物削減は重要な課題であり、特に2025年以降の改正建築物省エネ法やカーボンニュートラル実現に向けて、本論文の方法論は参考になる。ただし、日本の建設業界の特性（プレハブ工法など）を考慮する必要がある。
In the global GX context
This UK-focused study contributes to global construction decarbonization by demonstrating how waste-reduction practices can lower embodied carbon and costs. It aligns with circular economy principles and supports corporate sustainability reporting (e.g., CDP, TCFD) by providing quantifiable carbon reduction levers.
👥 読者別の含意
🔬研究者:Provides a reproducible methodology for measuring construction waste and linking it to carbon emissions at unit level.
🏢実務担当者:Offers concrete marginal gains—improved estimating and procurement—that social housing providers can implement to reduce costs and carbon.
🏛政策担当者:Highlights the potential for national-scale savings from small efficiency improvements, supporting policies that incentivize waste reduction in construction.
📄 Abstract（原文）
Building cost-effective homes that comply with stringent environmental regulations remains a significant challenge for the UK housebuilding sector, particularly for social housing providers. In the context of net zero targets and reducing embodied carbon, this study examines opportunities to minimise material waste and associated impacts. Using an inductive mixed-methods approach, the research began with a literature review to establish baseline waste rates across key material streams. It then analysed material usage data from three completed housing developments, comparing estimated quantities with actual orders and spend to identify discrepancies between assumptions and real-world outcomes. To validate these findings, a controlled case study tracked the construction of a single four-bedroom home, enabling direct measurement of waste rates and assessment of cost and carbon implications at unit level. Results highlight a series of marginal gains achievable through improved estimating and procurement practices, which collectively offer potential for significant financial savings and reductions in embodied carbon when scaled nationally. For social housing providers, these efficiencies could lower build costs, support sustainability goals, and create opportunities to reinvest in additional housing delivery.
