abstract={The construction sector has a substantial impact on the environment, primarily due to its excessive resource and energy consumption, along with significant waste production. Construction accounts for a third of the world's total waste and around 40% of global CO2 emissions. The phases of material production, construction, the facility’s useful life, and end-of-life components have been widely studied for their role in environmental pollution. Whilst minimising waste holds the highest priority in construction waste management, understanding the sources of construction waste can support effective reduction strategies. This paper aims to explore the relationship between the origins of construction and demolition waste (CDW), lean practices, construction productivity, and the associated environmental impacts. A quantitative research method was adopted, using a survey questionnaire to identify correlations between CDW origins, construction productivity, and environmental impacts. Findings revealed that 62% of CDW origins have a greater impact on the environment than on productivity. Additionally, eight specific CDW origins showed statistically significant relationships with the tested environmental variables. These insights can promote evidence-based decision-making by construction practitioners in developing effective strategies for waste minimisation. },
