Moving towards Net-Zero requires robust information to enable good decision making at all levels: covering hardware procurement, workload management and operations, as well as higher level aspects encompassing grant funding processes and policy framework development.

The IRISCAST project is a proof-of-concept study funded as part of the UKRI Net-Zero Scoping Project. We have performed an audit of carbon costs across a multi-site heterogenous infrastructure by collecting and analysing snapshots of actual usage across different facilities within the IRIS community ( This combines usage information with an analysis of the embodied costs and careful mapping and consideration of the underlying assumptions to produce an estimate of the overall carbon cost, the key elements that contribute to it, and the important metrics needed to measure it. We present our key findings, lessons learned, and recommendations.
