Wenner's Gulfstream jet has an optimal cruising speed of around 493 nautical miles per hour. (That figure, and the ones that follow, are based on calculations for a Gulfstream IIB, Wenner's longtime ride. In fact, according to sources, these days he may fly the slightly larger Gulfstream IV; a Wenner spokesman did not reply to calls for comment.)
At that speed, the plane would produce around 80 tons of carbon dioxide during the 20-hour round-trip voyage between New York and Athens, and another 33.6 tons flying between New York and Sun Valley. Fun fact: According to the Environmental Protection Agency's emissions calculator, you'd have to drive a Hummer H3 200,000 miles to generate the same amount of carbon.

Update:
..."Lending out the jet is a huge part of Jann's starfucking," says an insider. "It's half the reason he has the plane."
Moreover, according to another Wenner source, the Gulfstream isn't his only emissions-intensive vehicle. He also recently purchased a GMC Yukon Denali—an SUV whose fuel efficiency is on par with that of the Hummer—and also keeps a pair of snowmobiles at his place in Sun Valley, Idaho. Snowmobile engines are notoriously dirty, producing as much pollution in a day of use as a typical car does in 100,000 miles.
And Wenner isn't much better when he's in town, where he has a chauffeured Mercedes to shuttle him the 15 blocks or so between his apartment and his office. Even more wasteful is his lunch routine: a private chef prepares his meal at home, then staffers drive it down to the office, don black-and-white uniforms, and serve it to him on his personal china.
