The construction sector is responsible for a significant share of global greenhouse gas (GHG) emissions, driven largely by the production and use of conventional building materials such as concrete, steel, and bricks. Green building strategies that emphasize low-carbon materials have emerged as critical solutions to mitigate environmental impacts, reduce energy consumption, and promote sustainable development. This article explores the concept of sustainable green buildings with a specific focus on low-carbon materials — their definitions, types, benefits, challenges, and implementation frameworks. The literature review synthesizes research on material life cycle assessment, performance criteria, and global green certification systems. Methodological approaches include life cycle analysis (LCA) and system design frameworks for integrating low-carbon alternatives. Implementation strategies are examined across case studies and best practices. Results demonstrate the potential for significant carbon savings, improved indoor environmental quality, and long-term economic benefits. The article concludes with recommendations for policymakers, designers, and stakeholders, emphasizing the need for integrated design, policy incentives, and material innovation to drive large-scale adoption of low-carbon green buildings. Despite these advantages, several challenges hinder widespread adoption, including higher upfront costs, limited availability of certain materials, and gaps in technical knowledge among practitioners. Overcoming these barriers requires coordinated efforts in research, education, and policy-making to create supportive environments for innovation. Future research directions emphasize the development of novel low-carbon materials with enhanced performance and scalability to meet diverse construction needs.
