By your request, I added a few maps to filter the thousands of green hotels I have on the site. Let me explain how this all works.
The guide became watered down over time because I want to acknowledge and encourage places to do little things that are more responsible and healthy for guests. If you have a choice of only a few places and one does one or two good things while the other places do nothing? Choose the one making some effort.
Travelers regularly want to know what hotels are completely smoke free or use safe cleaning products but don't care about all the other stuff. So I created a green rating to allow me to give one leaf to places that are non-smoking, for example. The downside is that for some, it “clutters” the guide because there are more chains and places that are not really green or eco hotels.
The easiest and first solution is to create maps that highlight places with the higher green hotel ratings. I figured it was best to create maps to cover all the higher rated places in the US so you can decide what is best for you and how selective you want to be.
I didn't think it was worth going down to the lower ratings. The quantity rises and if green is really your priority, the lower ones aren't doing enough. You can still use the regular guide to pick those over places that do nothing at all.
Please let me know of any thoughts or suggestions on ways I can take it further and be even more useful.
