San Francisco fliers go green with carbon offset kiosks

San Francisco Chronicle:Air travelers at the San Francisco International Airport will soon be able to pay restitution for the carbon emissions caused by their trip. This spring, the airport plans to unveil self-service kiosk stations where users can purchase carbon offsets. The experimental program will make the airport the first in the nation to offer such a plan. 　

"We'd like people to stop and consider the impacts of flying," said Steve McDougal, executive vice president for 3Degrees, a San Francisco firm that sells renewable energy and carbon-reduction investments and is teaming up with the airport and the city on the project.
