Perhaps I should have read Joel Makower's post on Wal-Mart's new green labeling system before blogging about it last week, as he knows far more about it than the Wall Street Journal does, having seen early versions of it and talked to many parties involved with the effort.
The two big letdowns for me are (1) that the labels will address only product manufacturers, not specific products, and (2) that Wal-Mart isn't actually rating anyone (companies or products), because it hasn't set any performance benchmarks.
Which is not to say that the whole thing is crap, but... You can read his post in full here.
