British Airways gave us the option of paying extra for carbon credits to make up for our air travel. We didn’t take them up on the offer. There are a number of reasons why I feel carbon offsetting is a bad thing. The first is that by removing the guilt, it encourages people to continue a profligate lifestyle, rather than actually changing their behavior. For example, if Al Gore genuinely gave a crap about the environment, he would stop flying by private jet so much.
