@holly_cummins we need more papers like this, so am currently going through it. Thought I would share a piece on PUE as you mention it in the doc -> https://perspectives.mvdirona.com/2010/05/pue-is-still-broken-and-i-still-use-it/ incase you had not seen this before.
PUE is Still Broken and I still use it – Perspectives

@094459 I hadn't seen that about PUE, thanks! Very interesting. My takeaway from it is "everything is wrong, and making it right is hard because complexity" (which is my general understanding of the carbon measurement landscape in general 😕 )

@holly_cummins @094459 Is anyone using CUE (sorry if that’s a naïve question)?

@TomRaftery @094459 I haven't seen it used myself, but I’ve only skated the surface of the infrastructure side of things.

@holly_cummins @094459 If I remember correctly, Facebook used it initially when reporting their DC's effectiveness - not sure how widely it is used now
