How green is CES?

Here.

Excerpts:

The cost of the CES carbon tax: $108,000. No, there's not a zero or three missing from that number. For the price of a Tesla Roadster and change, CES is cleansing the collective environmental sins of 140,000 people. Without wading into the controversial arena of carbon offsets or questioning the good intentions of CES' organizers, that number begs an obvious question: If neutralizing a looming global catastrophe comes so cheap, wouldn't have Bill and Melinda Gates just have written a check by now?
...
According to Carbonfund.org's website, CES' money will be invested in such things as buying renewable energy certificates from wind farms and planting trees in Nicaragua and Hungary.

CarbonFund is also letting conference-goers offset the considerable CO2 emitted by jets ferrying more than a hundred thousand people into Las Vegas. That's also a bargain: the bill for the six Fortune Magazine reporters who flew into town for CES from New York and San Francisco comes to a grand total of $23.81. At that price, you almost feel guilty about paying so little to not to feel guilty about your contribution to global warming.
