摘要
环境权益交易能够帮助以较低的成本实现既定的温室气体减排目标,在我国"双碳"目标的实现中扮演着重要角色.目前,我国有多种与碳减排相关的环境权益交易机制在同时运行,它们之间的交叉重叠和不完善的核算规则体系可能导致巨大的碳减排效益重复计算风险,从而影响环境完整性.文中系统分析了我国与碳减排相关的环境权益交易机制及其可能导致碳减排效益重复计算的机理.为避免碳减排效益的重复计算风险,应该加强顶层设计,从建立统一的管理平台、加强信息共享、完善碳排放统计核算体系、明确各种机制的定位与边界、避免不同机制的交叉和冗余等方面入手,加强机制之间的协调,优化总体的规则设计.
Abstract
Environmental rights trading can help achieve carbon emission reduction targets at a lower cost and play an important role in achieving China's carbon peaking and neutrality goals.Currently,various environmental rights trading mechanisms related to carbon emission reductions are operating in China.The cross-overlapping of these mechanisms and their imperfect accounting rule design may lead to a significant risk of double-counting of carbon mitigation benefits,where the same emission reduction benefit is used to achieve two or more mitigation targets,thereby affecting environmental integrity.This article has systematically reviewed the environmental rights trading mechanisms related to carbon mitigation in China and analyzed in detail the sources and mechanisms of the double-counting risk in environmental rights trading.It is suggested that in order to avoid the risk of double-counting of carbon emission reduction benefits,efforts should be made to strengthen top-level design and coordination between different mechanisms,including the establishment of a unified management platform,the enhancement of information sharing,the improvement of carbon emission statistics and accounting system,the clarification of the positioning and boundaries of various mechanisms,and the avoidance of the cross-overlapping of different mechanisms.
