Recent years have seen an increasing interest in the environmental impact, especially the carbon footprint, generated by the often large scale computing facilities used by the communities represented at CHEP. As this is a fairly new requirement, this information is not always readily available, especially at universities and similar institutions which do not necessarily see large scale computing provision as their core competency. Here we present the results of a survey of a large WLCG Tier 2 with respect to power usage and carbon footprint leveraging all sources of information available to us: Power usage data collected from built-in host level monitoring and external aggregates from the power distribution units at rack level; data sheets provided by the hardware manufacturers and the specifics of data centre that hosts our infrastructure.
We show that it is possible to estimate the environmental impact without having to invest in dedicated monitoring equipment, but also discuss the limitations of this approach.
