沱江流域协同推进碳达峰碳中和的碳排放权分配研究

Research of Allocation of Carbon Emission Rights for Carbon Peaking and Carbon Neutrality in the Tuojiang Basin

在碳达峰碳中和目标约束下,以经济体量、历史排放责任、公平性为基本原则设计沱江流域碳排放权分配方案,构建碳排放权分配指标,测算2021—2030年各市、州的碳排放配额,并确定地区碳排放权分配规则。研究结果表明:①2021—2030年沱江流域整体碳排放配额为32.36亿t,并呈现逐年上升趋势,其中2021年增量最少,2029年增量最多。②综合加权平均方案能兼顾各方利益述求,相较于单一原则的分配方案更为优化。③加权平均方案既对经济发展水平较高区域成都提出了较高的碳排放约束要求,也对发展相对滞后、历史排放量较小的阿坝进行补偿。

Under the constraint of the goal of carbon peaking and carbon neutrality,this paper designed the carbon emission rights allocation scheme for the Tuojiang Basin based on the basic principles of economic volume,historical emission responsibility and equity,constructed the carbon emission rights allocation index,calculated the carbon emission quotas of each city and prefecture during 2021—2030,and determined the regional carbon emission rights allocation rules.The research results showed that the total carbon emission quota of the basin in 2021—2030 would be 3.236 billion tons,and presented an increasing trend year by year,with the least increment in 2021 and the most increment in 2029.The comprehensive weighted average scheme could take into account the interests of all parties and would be more optimized than the single-principle distribution scheme.The weighted average scheme not only put forward higher carbon emission constraint requirements for Chengdu,a region with higher economic development level,but also compensated Abaperfecture,which was relatively backward in development and had low historical emissions.
