New Framework for Net-Zero Construction Supply Chains: A Boost for Sustainability Research

A team of researchers from Massey University has developed a conceptual framework that integrates net-zero principles into supply chain performance evaluation in the construction sector, aiming to reduce carbon emissions and enhance resource efficiency. The study, led by Isuru Hettiarachchi, utilized a systematic literature review to identify key supply chain decarbonization performance indicators, tools, challenges, enablers, and improvement opportunities. The research has provided a novel and practical framework that addresses the gap between digital tools, decarbonization metrics, and policy or organizational considerations.

Key Takeaways:

• The construction industry is a major contributor to global carbon emissions, highlighting the need for net-zero targets in material supply chains.
• Evaluating supply chain performance is crucial for reducing emissions, enhancing resource efficiency, and supporting sustainable decision-making.
• The study aimed to develop a conceptual framework that embeds net-zero principles into supply chain performance evaluation within the construction sector.
• A systematic literature review was conducted using PRISMA guidelines, covering 54 peer-reviewed articles published between 2016 and 2025.
• The review identified key supply chain decarbonization performance indicators, tools, challenges, enablers, and improvement opportunities.
• The results reveal the growing use of life cycle thinking, carbon accounting, and digitalization, shaped by policy, data access, technological readiness, and stakeholder coordination.
• The framework integrates these factors to guide a structured, net-zero-aligned supply chain.
• The study contributes a novel and practical framework that addresses a critical gap in the field.
• The research emphasizes the importance of stakeholder coordination, data access, and technological readiness for effective decarbonization.

Statistics:

• 54 peer-reviewed articles were analyzed in the systematic literature review.
• The research focused on the period between 2016 and 2025.
• The construction industry accounts for 11-13% of global carbon emissions.
• The net-zero targets aim to reduce emissions by 45% by 2030.
• The framework provides a structured approach to evaluating supply chain performance.
