I wonder if it also factors in travel for remote employees though. Every fully remote company I’ve ever worked for has had regular in-person meetups where people fly to some central location a few times a year.
I doubt there are all that many people meeting the following conditions: work for small companies with one office, live far enough away from that office to need to fly, work for a company with enough extra money sitting around to fly everyone out, work for a company that wants to fly everyone out, are willing to fly out. I really doubt there are enough to have much impact on carbon emissions.
