The Greenwashing Line

I wrote previously in my post, Wal-Mart, Sustainability and the Line, about businesses who are trying to improve their environmental practices. I asked where the line was for companies who businesses were not sustainable, i.e., Wal-Mart, but who were trying to adopt more sustainable business practices. I argued that the fact that they were doing something was better than doing nothing. Today, I read an interesting blog post that agrees and asks, How Bad Is Greenwashing, Really?
