That's right up there with the energy credits you can buy at Whole Foods, which so far as I can tell, are very careful to avoid saying that they will do anything for the planet or anyone else, other than put you in a save the planet, pictures-of-windmills state of self-deluded oneness with Gaia.
It reminds me of when Seventh Generation got snookered into selling those "ionized disks" that would clean your clothes without detergent and last forever. The reality is, there's enough detergent residue in all your clothes that you can wash them with nothing a couple of times and still get them clean. By the time you figured out the ionized disks were worthless, it was too late to return them. Seventh Generation, at least, realized they'd been stupid and refunded everyone who returned them anyway, but a certain Hollywood religious group was supposed to have been involved in selling them too and was far less scrupulous.
