This study addresses Nigeria’s significant yet understudied role in global carbon emissions, where the construction sector contributes up to 37% of energy- and process-related CO₂ emissions amid rapid urbanization and limited regulatory frameworks. Employing a quantitative empirical approach, data were collected via questionnaire surveys from 200 industry professionals and experts, including architects, engineers, quantity surveyors, and urban planners. Principal Component Analysis (PCA) was utilized to identify key factors influencing carbon emission reduction through carbon trading practices. The literature review underscores the imperative for emission minimization in construction and elucidates carbon trading’s role in fostering sustainability. Findings reveal that carbon trading promotes industrial upgrading, optimizes energy structures, and stimulates low-carbon technological innovation within the Nigerian construction industry. The study concludes that the construction sector should adopt green building principles and carbon trading mechanisms to curb pollution effectively. Recommendations include enhancing awareness and education among professionals, investing in low-carbon R&D, and implementing supportive policies tailored to Nigeria’s context. These measures can significantly reduce the sector’s carbon footprint, contributing to sustainable development. This research provides valuable, Nigeria-specific insights for policymakers, practitioners, and stakeholders committed to sustainability in construction, bridging global knowledge with local gaps.
