范围本议定书为估算提供或采购低碳或零碳信息和通信技术（ICT）服务可能导致的减排提供了指导。这是一个越来越重要的话题，不仅因为信息和通信技术对环境的影响越来越大，还因为信息和通信技术作为一种服务提供的技术复杂性，特别是在云计算的使用和通过互联网提供信息和通信技术服务方面。该议定书既可用于为碳交易创造可核查的减排，也可用于在公司可持续性报告中量化和报告相关的低碳或零碳ICT举措。

ScopeThis protocol provides guidance for estimating the emission reductions that could result from the provision or sourcing of low or zero carbon information and communication technology (ICT) services. This is an increasingly important topic not only because ICT has growing environmental impacts, but also due the technical complexities which underlie the delivery of ICT as a service, especially in respect of the growing use of cloud computing and the provision of ICT services over the internet. The protocol can be used both for creating verifiable emission reductions for carbon trading, and the quantification and reporting of related low or zero carbon ICT initiatives within corporate sustainability reports.
