Just a suggestion, but placing some of the conference fee into buying carbon credits might make the gig a little greener....?

That's an excellent idea. I will ask Alex if we can make that a "button" for the Kagi web site - if we make it optional then no one can object too much. I will also ask a student to do a "back of the envelope" calculation of our "footprint" and see if we can embed that figure into a carbon credit purchase AND an objective for reduction in future conferences. If you have any pointers on a good carbon impact calculator, I'd be interested in hearing about it. ...r
