建筑碳交易过程的碳排放核算

Carbon Accounting in the Construction Carbon Trading Process

基于目前碳排放-碳交易现状,以核算范围为切入点,提出适用于我国的碳排放核算方法,并明确了碳排放核算边界条件。基于边界条件原则,将建筑碳交易与碳排放核算联系起来,根据是否考虑间接排放、是否允许建筑交易单位自主选择使用能源得出三种常见的碳排放-碳交易组合情况,并针对三种情况,结合是否沿用建筑能耗限额、是否沿用单位建筑面积能耗指标来进行配额分配的问题,进行一一分析对比,并随之提出相应的碳交易配额分配方案。

The paper first proposes a carbon emissions accounting method of buildings applicable to China based on the current carbon emission-carbon trading status, which clarifies the carbon emission accounting boundary conditions. Then the paper combines building carbon trading with carbon accounting and introduces three common carbon emission-carbon trading combinations depending on whether indirect emissions are considered, whether construction trading companies are allowed to use energy independently. Finally, the paper puts forward the carbon trading quota allocation schemes for those three combinations considering whether building energy consumption quota is used, whether building energy usage intensity indicator is applied to solve the quota allocation problem.
