日本語
従来の建設資材（セメント、焼成レンガ、鋼、木材）は高い内包エネルギーと環境負荷を伴うため、竹、再生鋼、フライアッシュレンガ、ラムドアース、低炭素コンクリート等の代替材の環境影響をナイジェリア・ジョス市で実証的に評価した研究。代替材は炭素排出・廃棄物を削減し資源を保全するが、認知度の低さ、政策執行の不備、技術知識不足、初期コスト高が普及を阻害している。環境規制強化、グリーン建設へのインセンティブ、研究開発投資、啓発活動を提言する。
English
This study empirically evaluates sustainable alternatives to conventional construction materials (bamboo, recycled steel, fly ash bricks, rammed earth, low-carbon concrete, recycled plastic) in Jos, Nigeria. Findings show alternatives cut carbon emissions, waste, and resource depletion, but low awareness, weak policy enforcement, limited technical know-how, and high upfront costs block adoption. It recommends stronger regulation, green-building incentives, R&D investment, and awareness campaigns for developing economies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では、建設業のScope 3排出（セメント・鋼材等の調達段階）や embodied carbon 開示、グリーンビルディング認証との接点がある。ただし本論文はナイジェリアの地域事例であり、日本のSSBJ・有報対応への直接的な示唆は限定的で、途上国における建設脱炭素の比較事例として参照する位置づけとなる。
In the global GX context
While framed around Nigeria, this paper speaks to the global embodied-carbon agenda in construction — a sector increasingly targeted by CSRD, ISSB, and green-building disclosure regimes. It adds developing-economy empirical evidence on adoption barriers (awareness, policy enforcement, upfront cost), complementing the largely OECD-focused literature on low-carbon building materials and procurement standards.
👥 読者別の含意

🏛政策担当者:途上国における建設脱炭素政策の設計に、規制執行・インセンティブ・啓発の必要性を示す事例を提供する。
📄 Abstract（原文）
The growing rate of urbanization and infrastructural development across the world has intensified the demand for construction materials, leading to severe environmental consequences such as greenhouse gas emissions, deforestation, depletion of natural resources, and ecological degradation. Traditional construction materials including conventional cement, fired clay bricks, steel, and timber are associated with high embodied energy and environmental pollution. Consequently, the search for sustainable alternatives has become a critical concern within the global construction industry. This study examines alternatives to traditional construction materials and evaluates their environmental impacts with particular attention to Nigeria and Jos metropolis in Plateau State. The study adopts an empirical approach using questionnaires, interviews, and secondary data obtained from professionals in the construction industry. The paper explores sustainable alternatives such as bamboo, recycled steel, fly ash bricks, rammed earth, low-carbon concrete, and recycled plastic products. Findings reveal that alternative construction materials significantly reduce carbon emissions, minimize waste generation, conserve natural resources, and improve environmental sustainability. However, challenges such as low awareness, poor policy implementation, inadequate technical knowledge, and high initial costs hinder widespread adoption in Nigeria. The study further reveals that Jos metropolis possesses substantial potential for sustainable material adoption due to the availability of local earth materials and increasing awareness of environmental conservation. The paper concludes that sustainable construction materials offer practical solutions for reducing environmental degradation while promoting resilient and affordable housing development. It recommends stronger environmental regulations, incentives for green construction practices, investment in research and development, and public awareness campaigns to encourage the transition from traditional to sustainable construction materials in Nigeria and other developing economies.
