The Ventura County (CA) Sustainability Council has tackled environmental issues for a number of years, they are not "johnny come lately" players in the green space. The group is in the process of designing a new website and logo and draft designs included the dollar symbol, much to the consternation of council members. David Goldstein, environmental resource analyst for the county of Ventura, put it rather nicely in his summary of the meeting when he said:
Environmental rhetoric occasionally casts profit as a force leading to pollution and consumption of resources...  Economics is as important for sustainability as two other "E" factors: environment and social equity.
Regardless of your definition of the "Triple Bottom Line" - whether you call it "Ethics (or equity)/Earth/Economics" or "People/Planet/Profit" or even "Community/Climate/Commerce" - the end result is that without commerce, without profit, the whole thing comes to a stand still.
