Starting in the Spring, San Francisco International Airport will have kiosks where flyers will be able to purchase carbon offsets. This will be the first of its kind and sounds like an interesting idea. Since people are usually bored waiting for their flights, a kiosk will intrigue people to do some minor splurge spending to help the environment. The offsets are not tax deductable and are provided by 3Degrees, a San Francisco firm that sells renewable energy and carbon reduction investments. As you can see from the chart above, the offest price is minimal and 3Degrees gets 30% of it while the rest goes to carbon reduction projects.
