Analysis of carbon emission reduction potential of construction industry in Liaoning Province based on system dynamics

Abstract

 The rapid increase in carbon emissions is one of the main causes of environmental degradation, and the construction industry contributes 40% of carbon emissions. This paper uses system dynamics to analyze the carbon emission reduction potential of construction enterprises in Liaoning Province in order to realize the national "dual carbon" goal as soon as possible. First, the factors affecting carbon emissions are summed up by combining the calculation formula of carbon emissions of buildings in the whole life cycle and related literatures. Then use the environmental characteristics of Liaoning Province to establish a carbon emission reduction model, carry out simulation simulation and validity test, and obtain the relationship between the influencing factors and carbon emission reduction. Finally, a scenario analysis is carried out in four aspects: energy technology, building materials production technology, transportation technology and waste recycling technology. A series of conclusions are drawn, such as building materials production technology and energy technology are the key aspects of implementing carbon emission reduction in the construction industry in Liaoning Province. The whole work provides a theoretical basis for Liaoning Province to successfully achieve the "14th Five-Year" goal, and then achieve carbon emission reduction and sustainable development.
