At least there’s that: I live in a world where some people care about it and publish their viewpoint in the latest CACM. Read it on your next flight. Some interesting things that won’t shock anyone:
There’s a nice picture with different environmental costs based on the location of the conference. It also shows that people like to go to nearby conferences, one of the reasons why “The impulse to ignore the issue is entirely understandable.” For more perspective see some of our earlier posts for example here and here.
The viewpoint also reports on a recent switch from in-person to online program committees for flagship conferences (POPL and ICFP), following a recent trend. For starters we continue to suggest that STOC and FOCS do the same, because the nature of decisions does not justify the cost. The latter post also includes hard numbers on the added value of a physical meeting (with respect to accept/reject decisions — of course one can value at infinity meeting in person luminaries in your field, but that can be done in other ways and should not be tied to PC meetings).
