Efficiency improvements over the past decade have meant that data center energy usage has decoupled from the growth in IT workloads. Much of this efficiency improvement has been attributed to innovations made by “hyperscale” public cloud vendors, where a large proportion of new IT workloads are now being deployed. However, the move to the cloud is making it more difficult to assess the environmental impact of workloads deployed there. Although the large cloud vendors are amongst the largest purchasers of renewable electricity, customers do not have access to the data they need to complete emissions assessments under the Greenhouse Gas Protocol. Data such as Power Usage Effectiveness, emissions factors and equipment embodied energy are not available from public cloud vendors. This paper demonstrates how the Greenhouse Gas Protocol method of assessment of IT emissions does not work for public cloud environments and suggests how this can be tackled by the cloud vendors themselves.

评估《温室气体协议》对于计算公共云计算工作负载排放的适用性

在过去十年中，效率的提高意味着数据中心的能源使用量已与IT工作负载的增长脱钩。这种效率的提高大部分归功于“超大规模”公共云供应商的创新，现在大量新IT工作负载正在部署中。但是，迁移到云使得评估部署在其中的工作负载对环境的影响变得更加困难。尽管大型云供应商是最大的可再生电力购买商之一，但客户无法访问完成《温室气体协议》下的排放评估所需的数据。公共云供应商无法提供诸如电源使用效率，排放因子和设备包含的能量之类的数据。
