More on purchasing carbon offsets

The people at Clean Air - Cool Planet have put compiled a nice guide (pdf) to the many companies selling carbon offsets.

If you are thinking about donating money to go carbon neutral - which was named 2006 word of the year by the New Oxford American Dictionary, quite an accomplishment given the tough competition (surge anyone?) and the small matter of being, er, two words - spend five or ten minutes reading through the guide first.

There's a lot of money in carbon guilt these days. Companies have rushed into the game with bold promises to gobble up your carbon emissions but without any oversight.

The Retail Offsets Guide has kind words for three North American based companies -- Climate Trust, NativeEnergy and Sustainable Travel (a subsidiary of the Swiss company Myclimate).
