ISO 14064的这一部分规定了原则和要求，并在项目层面上为旨在减少温室气体（GHG）排放或增强清除的活动的量化、监测和报告提供了指导。它包括规划温室气体项目、识别和选择与项目和基线情景相关的温室气体源、汇和水库、监测、量化、记录和报告温室气体项目绩效以及管理数据质量的要求。ISO 14064是温室气体计划中性。 如果GHG计划适用，则该GHG计划的要求是ISO 14064要求的补充。注:如果ISO 14064的要求禁止组织或GHG项目支持者遵守GHG计划的要求，则以GHG计划的要求为准。

This part of ISO 14064 specifies principles and requirements and provides guidance at the project level for quantification, monitoring and reporting of activities intended to cause greenhouse gas (GHG) emission reductions or removal enhancements. It includes requirements for planning a GHG project, identifying and selecting GHG sources, sinks and reservoirs relevant to the project and baseline scenario, monitoring, quantifying, documenting and reporting GHG project performance and managing data quality. ISO 14064 is GHG programme neutral. If a GHG programme is applicable, requirements of that GHG programme are additional to the requirements of ISO 14064. NOTE If a requirement of ISO 14064 prohibits an organization or GHG project proponent from complying with a requirement of the GHG programme, the requirement of the GHG programme takes precedence.
