Dreamhost is the latest provider to jump on the 'green' bandwagon. What that normally means is that they're tree-hugging, bagel eating hippies (most dreamhost employees are, I hear) but in this case it means they're carbon neutral.

Carbon neutrality means that a project, organization or person can purchase credits to have someone else plant trees on their behalf, reduce emissions elsewhere, etc.

I personally would prefer if companies would get out there and donate their time instead: Plant trees, go around town telling other businesses & get involved directly but at least this is a step in the right direction.

Paying someone else to do it on your behalf just seems like the lazy man's way out.
