How much material, every year, gets wasted or manufactured for no good reason except to fill gift bags at conferences? Including the bags themselves? The bag for this conference is not even particularly generous, but I'm still looking at a pair of branded flip-flops, a set of laptop screen cleaners, a mousepad, some kind of IP phone gadget, two magazines, and assorted promotional cards. When I think about the sheer number of CDs, USB Keys, rubber toys, and assorted office junk that gets thrown at conference attendees each year--not to mention millions of branded nylon tote bags--almost all of which will probably be thrown away or forgotten within a week, it makes me shudder.
The tech industry is not particularly good at being sustainable in the first place. There's potential there, don't get me wrong--just by digitally delivering movies and music, we could theoretically save a tremendous amount of plastic and industrial pollutants that go into CDs and DVDs. But as it is right now, hi-tech doesn't usually mean good for the environment. It would probably not make much of a dent in the overall impact if conference sponsors went green with their swag, but it would be a nice symbol.
