Travelers flying out of San Francisco International Airport can be the first in the nation to wipe away some of the damage their flights wreak on the planet by swiping their credit cards.
On Thursday, the Bay Area's largest airport unveiled three Climate Passport kiosks with touch screens that determine how many pounds of carbon dioxide a trip will produce, calculate the sum an environmentally conscious traveler should contribute to projects in San Francisco and California that help reduce greenhouse gases, then allow fliers to purchase certified carbon offsets.
"We realize people are going to fly," said Steve McDougal, executive vice president of 3Degrees, a San Francisco company that helped SFO develop the program. "This gives them something they can do to reduce their impact. This is just one of many small things people need to do."
The kiosks are located near the entrances to Terminal 3 and international terminals A and G - behind security checkpoints and perched in front of large signs reading, "Keep our skies blue. Purchase your air travel carbon offset here."
