You can get a copy of the guide here: Environmental Claims: A Guide for Industry and Advertisers
One item I found particularly interesting was the entry on sustainability claims. Here is what the guide says:

In the spirit of honest advertising and useful information, I have to agree that a claim of achieving sustainability would be inappropriate within the systems thinking paradigm.
I haven’t had a chance to completely read the guide but based on a quick review, it looked like a responsible list of criteria we could all adopt as we go forward with our green business, working towards sustainability.
