The construction industry remains heavily reliant on conventional building materials, which are widely associated with significant environmental degradation. To address these challenges, various sustainable construction practices have been implemented globally, aiming to minimise the environmental impact of building activities. This study explores the role of sustainable construction in mitigating environmental degradation amid rapid urbanisation and growing infrastructure demands. Using a quantitative survey of construction professionals in South Africa, the research identifies key sustainable practices prioritised within the industry. Findings reveal that resource and energy efficiency are viewed as the most effective strategies to reduce environmental impacts, while broader ecological concerns, such as climate change mitigation and environmental preservation, receive moderate attention. Social and design-related factors, including occupant health and sustainable architectural design, are recognised but underemphasized. Additionally, environmental awareness and adoption of alternative building technologies face challenges due to knowledge gaps, cost, and regulatory barriers. The study highlights the need for integrated approaches that balance immediate resource management with long-term ecological stewardship and social well-being. It recommends strengthened policy frameworks, education, and incentives to support sustainable construction practices that align with global sustainability goals and promote environmental resilience.
