I haven't fully formed this thought yet, but your request might result in a net loss of "good" people. The people who actually consider your request will probably fail to launch their business due to those environmental constraints. If you take 10 people who run a business regular and compare them to 10 who do it in an environmentally conscience way (while environmentalism not being he the bizmodel in the first place), I'd think you'd have equal or less environmental businesses succeeded which actually ends up hurting your problem more than helping.

I think the ideal way is to let a startup thrive any way possible and when they're not trying to not starve anymore, begin environmental changes.
