Much has been written about the pros and cons of carbon offsets. The idea, if you haven’t been following, is that you pay money to a nonprofit organization to plant trees or invest in renewables or otherwise reduce the amount of carbon in the atmosphere in an attempt to offset the carbon you’ve generated.
There are many calculators online that help you to figure out how much carbon you’ve generated and where you should donate it. Carbon Footprint is a nice flexible one that lets you calculate individual aspects of your life as opposed to doing a whole audit – both can be good, but since I’m on the road, my lifestyle doesn’t easily fit into many of these calculators. Since my main impact is travel, I figured my mileage and multiplied the air travel by 1.9 to account for the increased impact airplane emissions have (the amount used by Carbon Footprint). It then lets you select from a variety of worthy projects from Kenya to Central America.
Critics compare this system with the Catholic Church’s system of indulgences in Medieval times – a system that allowed people to “buy” forgiveness for their sins by making donations to the Church. They argue that there’s a wide variance among carbon offsetting groups, none of them are regulated and there’s no way to know for sure that the trees you’re paying to plant wouldn’t be planted anyway.
