Carbon neutrality，翻译为“碳中和”，节能减排术语。Carbon neutrality是指国家、企业、产品、活动或个人在一定时间内直接或间接产生的二氧化碳或温室气体排放总量，通过植树造林、节能减排等形式，以抵消自身产生的二氧化碳或温室气体排放量，实现正负抵消，达到相对“零排放”。

Climate neutral，翻译为“气候中和”，气候中和是指当一个组织的活动对气候系统没有产生净影响。在气候中和的定义中，除了尽可能实现各种温室气体的净零排放，还必须考虑区域或局部的地球物理效应

Zero Emission，翻译为“零排放”，是指无限地减少污染物和能源排放直至为零的活动：即利用清洁生产，3R(Reduce,Reuse,Recycle)及生态产业等技术，实现对自然资源的完全循环利用，从而不给大气，水体和土壤遗留任何废弃物。

参考双语例句：

为证明这种方式具有合理性， 德国政府强调说，巴布亚新几内亚作为一个小岛屿国家，已经在《联合国气候变化框架公 约》（《气候公约》）之下承诺在 2030 年之前实现减少一半排放的目标，并在 2050 年之 前实现碳中和。
