陈迎 | 碳中和概念再辨析
1 碳中和概念溯源
1.1 第一阶段:碳中性作为生物碳循环的概念早已有之
1.2 第二阶段:碳中和理念萌芽,企业为个人和家庭客户提供碳抵消服务
1.3 第三阶段:借助大型赛事,碳中和理念在国内进一步传播
2 碳中和成为全球应对气候变化目标
2.1 《公约》提出稳定浓度目标
2.2 《坎昆协议》明确2 ℃温控目标
2.3 《巴黎协定》提出碳中和目标
3 不同碳中和目标的内涵和差异
3.1 各国对碳中和目标的表述

3.2 IPCC报告对碳中和的相关表述
注:资料来源为作者根据IPCC报告整理。
4 碳中和目标的要素及概念辨析
4.1 碳中和对象:人为而非自然
4.2 实施主体:针对多元主体确定核算边界
4.3 气体种类:二氧化碳或碳当量
4.4 主要实现路径:碳减排与碳移除
5 结 论
