Optimization of Carbon Allowance Allocation Mechanism for Construction Industry
In the context of carbon trading mechanism,through analysis of the carbon emission sta-tus of the construction industry from 2019 to 2021,it is found that the current carbon quota alloca-tion system of the construction industry lacks fairness.Therefore,a carbon quota allocation model based on grey forecasting model(GM(1,1))and entropy value-coefficient of variation is estab-lished,and the carbon quota allocation results of life cycle assessment(LCA)of the construction in-dustry in 2030 are finally derived.The results show that with 2030 as the base year,the total carbon quota in the production phase of building materials will reach 3 817 728 200 tons,the construction phase will reach 7 229 066 000 tons,and the operation phase of building will reach 2 448 070 300 tons.Under the premise of unchanged control of the total amount of allocation,among the carbon emission sources in each stage,cement,electricity,urban residential buildings and public buildings are needed to significantly reduce carbon emissions in order to meet the target.The construction in-dustry can refer to this quota allocation standard to control carbon emissions at each stage in order to meet emission reduction standard in this industry.
