So, here I was, in my previous post, being all jetsetty and stupid about sitting on a flight to Prague and flipping through magazines in search of a Eureka moment. (You've got to admit, though, it was nowhere as bad as Tyler Brule's endless columns that appeal to people who need their dose of rare elitist cool that only radiates from articles written by a rich guy who spends his life in transoceanic levitation.)

"Business travel accounts for 65 percent of all flights within the United States," reports Katharine Mieszkowski in Salon, quoting figures from travel-research company PhoCusWright. Read the article here, it's packed with useful information about emissions related to air travel.

I'm here to state the obvious: if you can skip a flight, do it. And use Skype instead for that oh-so-important meeting. Yes, the chain of events that led to the manufacture and distribution of your PC, webcam, headset, or WiFi phone did create a negative environmental footprint. So the physical stuff that Skype needs is far from squeaky clean when you've got your green-colored glasses on. But using Skype sure beats the hell out of binge flying. Oh yessireebob.
