欧盟PEF中的循环足迹公式CFF学习笔记-1-CFF公式整体介绍

以下内容为个人在学习过程中形成的观点，不作为咨询建议或政策解释。

本系列的讨论基础为欧盟于2019年发布的PEF方法文件，第4.4.8节 End of life modelling。

（https://eplca.jrc.ec.europa.eu/permalink/PEF_method.pdf）

本系列内容是个人观点，仅作参考。

本系列的内容打算通过以下框架展开：首先是整体介绍，然后是CFF公式三部分的介绍，然后是各参数的介绍。（目前是这样的打算，实际怎么写看实际情况）

循环足迹公式
首先整体介绍一下循环足迹公式，来看公式全貌
CFF整体上由三部分组成：

CFF = Material + Energy + Disposal

即
CFF=材料循环+能量回收+最终处置
CFF-材料循环
材料循环部分由三个部分组成，
第一部分的含义是：产品生产时使用的原生材料的环境负担
第二部分的含义是：产品生产时使用的再生材料的环境负担
第三部分的含义是：产品在未来走到生命末期时，因参与材料循环而产生的环境负担与收益
CFF-能量回收
能量回收部分，指的是产品在未来走到生命末期时，因参与能量回收而产生的环境负担与收益。
如果只看第一个乘号后面的括号里的内容，也由三个部分组成，
第一部分的含义是：能量回收过程产生的环境负担
第二部分的含义是：能量回收过程因替代热能生产而产生的环境收益
第三部分的含义是：能量回收过程因替代电能生产而产生的环境收益
CFF-最终处置
最终处置部分，指的是产品在未来走到生命末期时，因未参与材料循环与能量回收而产生的环境负担。
也就是真正被丢弃/非资源化利用处置而产生的环境负担。
下一篇文章应该会介绍CFF-材料循环部分。
