For those who are into carbon offsetting there is a new search engine on the web which donates all its profits to recognised carbon offsetting projects. Yamoogle.com 

Carbon offsetting is a dubious science and most certainly should not be a substitute to becoming less wasteful and less polluting at a personal level. However, if it helps to create or protect good wildlife habitat and to bring low polluting technology to areas where it would not otherwise be used, carbon offsetting cannot be seen as a bad thing – just not a solution in itself.

Yamoogle.com claims that by using it as your search engine of choice every day, one can offset 18.1 tonnes of carbon per year. Worth a try I guess.
