Optimizing the cross-regional allocation paths of construction waste can not only effectively improve resource utilization efficiency but also significantly reduce carbon emissions, thereby promoting sustainable development. This paper explores the issue of optimizing cross-regional allocation paths for construction waste and proposes an optimization method that combines the shortest path algorithm with a carbon emission calculation model. Focusing on the distribution characteristics of construction waste and carbon emissions during transportation, the shortest path algorithm is used to determine the optimal allocation paths. By integrating optimized transportation routes and modes, efficient cross-regional allocation of construction waste is achieved, with effective reduction of carbon dioxide emissions in the process. This paper compares the changes in carbon emissions before and after optimization, verifying the feasibility and effectiveness of the proposed optimization method in reducing carbon emissions. Reasonable path optimization can not only reduce transportation costs but also achieve a win-win situation of environmental and economic benefits driven by carbon emission reduction goals.
