SFO 1st to let travelers buy carbon offsets, but what ARE carbon offsets?


Are carbon offsets “like a fat man paying a skinny man to lose weight for him?”

Not if you ask Gavin Newson, mayor of San Francisco, who helped bring carbon offset kiosks to that city’s airport. Last week, SFO became the first airport in the nation to offer air travelers a way to offset the greenhouse gases their flight will add to the Earth’s atmosphere.

A buildup of greenhouse gases, including carbon dioxide (CO2), is known to cause global warming.

Here’s how the three Climate Passport kiosks at SFO work:

  • you enter information about your trip on a touch screen
  • the computer calculates how many pounds of carbon dioxide (and other greenhouse gases) your trip will produce
  • it suggests how much you’d need to donate to local projects aimed at reducing greenhouse gases in order to “offset” the damage your trip will inflict on the environment
  • the money goes to renewable energy, energy efficiency, and reforestation projects, like Garcia River Forest and Dogpatch Biofuels
  • The kiosks are after the security checkpoints on both sides of the International Terminal, and in Terminal 3.

How much does a clean conscious cost? According to the computer, a trip from Vancouver to SFO and back, for instance, would produce 1,186 pounds of carbon dioxide, which could be offset with a contribution of $7.26, while a one-way trip from SFO to Boston would produce 1,999 pounds of carbon dioxide, which could be offset for $12.24.

Naysayers: Carbon offsetting is a complex issue, and the naysayers are already out in force, with hundreds commenting on Sfgate.com’s article on the kiosks, most of the comments were along these lines:

  • There’s a sucker born every minute.
  • Fool + money = parted
  • BUY THIS AND YOU ARE AS DUMB AS A STONE!!
  • PT Barnum would have been proud.

Funny, yes,  but I think this one is actually more accurate:

“I betcha a lot more people have an idea of how much carbon their flights are producing after having read this story than before. Fighting global warming is a hearts and minds struggle.”
