Management of Carbon Emissions Throughout the Building Life Cycle Based on the Analytic Hierarchy Process

The severe global warming driven by the large-scale emission of greenhouse gases has made the reduction of carbon emissions a critical priority for global economic and social development. Among various sectors, the construction industry stands out due to its significant consumption of natural resources throughout the building process, resulting in a considerable environmental burden. In China, carbon emissions from the construction industry account for approximately 40% of the total emissions. Therefore, mitigating carbon emissions in this sector is of the utmost importance. This study develops an evaluation model for low-carbon production management in construction enterprises, utilizing the Analytic Hierarchy Process (AHP). Through a case study, the research identifies practical challenges in implementing this model and offers actionable recommendations. Theoretically, the study provides a valuable reference for future research on energy conservation and emission reduction in the construction industry. In practice, it offers guidance to construction enterprises in achieving a low-carbon transition.
