One of the side effects of travelling so much is feeling guilty about my contributions to global warming. So I started doing a little research into buying carbon credits to offset my carbon contributions to the world. It seemed the best way to do so (in America) was through “Carbonfund”:http://www.carbonfund.org/site/, but my research here was fairly spotty. I’m normally leery about giving money to charities that aren’t that well established, but I think no charities on these lines are going to be well established. Do any readers have any suggestions?
