Well from a PR stand point sure.
I'm not coming out against this by any means as I personally think it's a great idea in theory.
I like playing the devil's advocate role and I'm just bringing up some obvious operational hurdles to starting something like this locally before everyone starts jumping on the bandwagon.
For example, whose to say that some proprietor gets on board with this idea, and once passes it's six step process and gets "certified green" by this organization, gets put on the website and proudly displays a sticker on their door and promotes it on their menus.
Then they quickly decide that it's not really not worth all the extra hassle and expense and they go back to the old way of doing things while still benefiting from the PR as being perceived as having a "green" operation?
I'm 100% certain that stuff like this happens from time to time at restaurants.
For example, this can easily be done with items on menus being promoted as "locally sourced" from such and such a farm when they are actually coming off the Sysco truck.
Personally I like to give people the benefit of the doubt, but I could easily see something like this happening.
