You never know where the S-word (okay, the good S-word) is going to jump out at you. I was reading the October issue of PRINT magazine, a graphic design journal, and found an article by Jeremy Lehrer, called "The Sustainability Saga." (If that link gives you trouble, go here, select Academic Search Complete, and search for the title.)
The article is about two companies working in communications about sustainability. Jonah Sachs, is the founder of Free Range Studios, and author of Winning The Story Wars. He has helped non-profits such as Greenpeace and Global Zero tell their stories in advertisements, and co-created Annie Leonard's classic film The Story of Stuff. That movie has been seen 35 million times on the web. Interesting piece.
