So what's the deal here?
The problem with planes is that it spews exhaust high up in the atmosphere, while computing devices don't actually have an exhaust per-se, and its "carbon footprint" has more to do with how the electricity is generated than anything else.
Would there be a "carbon" problem had the power been generated through hydro, or nuclear, or other methods that has small "carbon footprint"?
We have this overly excited environmentalist who kept asking us if it's possible to coordinate with the users here so that the desktops are shut-off unless there is an anti-virus / Windows update. She has no understand of how the updates are done (we don't have a set time schedule for Windows update, and SAV updates everyday), nor there is a way to ensure that even if the users forgot to cooperate, things would get done. We just don't have the infrastructure for lights-out management at the moment.
Not to mention the computing cluster inside the server room with the rest of the server, and a UPS the size of a car that runs 24/7 and gets loaded at the off hours...
