| Environmental key performance indicators for digital infrastructure adapting to climate change | Key performance indicators (KPIs) are essential to enable infrastructure operators to measure their progress against their sustainability goals and to act where needed to ensure they remain on target. However, at present operators take different approaches to what KPIs they report, and the methodologies used to calculate the KPI values. As operators face similar green & low-carbon and sustainability challenges – and as other stakeholders – investors, end-users – will increasingly wish to understand and review the sustainability of businesses – it makes sense to review the sustainability KPIs used in the industry and to seek the development of industry agreed KPIs. This Recommendation takes up the challenge of identifying KPIs for green and sustainable digital infrastructures adapting to the challenges of climate change.
In this Recommendation, the key performance indicators on assessing the environmental impact for digital infrastructures are presented. These KPIs include greenhouse gas (GHG) emission, water usage, power supply, ecosystem, waste and indirect enablement of GHG emission reduction, etc.
For adoption and use of green and sustainable network KPIs, the following points are considered:
– Identifying key metrics and developing a unified methodology for the industry.
– Industry efforts to identify and adopt KPIs enabling more granular reporting. For example, allowing operators to drill-down on the specific issues such as energy use in each part of the network – mobile, fixed, core – and ideally, at least for internal assessment, to the level of specific geographies and sites.
– Definition and adoption of structured and evolving reporting standards to facilitate the evaluation of the KPIs in an automated manner.
This Recommendation is intended to build upon and utilize the best practices of other telco sustainability benchmarking frameworks and related KPI definitions (such as ones proposed by GSMA [b-GSMA ESG Metrics]), and also leading consulting companies [b-ABI research] [b-STL Partners] [b-GlobalPartners]. The KPIs and the review framework are presented as a first step towards in-depth analysis of the sustainability requirements. As the industry gains experience with the metrics, the KPIs and the framework are expected to ensure that it is fit for purpose. This ensures that the KPIs and framework continue to be aligned with work in other industry bodies – with the ultimate aim of ensuring a single set of industry wide agreed KPIs.

L.1327
| Guidelines on the selection of cooling technologies for data centres in multiple scenarios | Recommendation ITU-T L.1327 describes a universal data centre cooling technology selection method at its current industry development stage by matching detailed analysis of such technology and typical application scenarios.
1)Industry mainstream data centre cooling system solutions are categorized and summarized, and their technical principles, characteristics and routes analysed in detail to provide a basis for technology selection.
2)The complete cooling system is then divided into a number of processing components, and key factors affecting their performance are identified by analysing their technical principles.
3)Common data centre application scenarios are then classified from different dimensions, excluding those that have little or no impact on cooling, to identify appropriate scenarios for the performance of each processing component in a cooling system.
4)Single dimensional application scenarios are integrated into those that are multi-dimensional in line with the actual situation. Corresponding cooling system processing components are then integrated into a complete cooling programme to finalize technology selection for a data centre project.
Current data centre cooling technology presents complex, diverse and fast update characteristics. There are many factors affecting actual application of cooling technology and data centres are usually faced with multi-dimensional and complex scenarios. A selection method for an appropriate cooling technology in different application scenarios has become key to the safe energy-saving operation of a data centre.
