Out of all the awkward points that could possibly be raised about the 2011 Newsweek Green Rankings, here's one that simply proves how useless such ranking systems are (via Joel Makower):
"Nike’s fall — from #10 in 2010 to #243 this year — was perhaps surprising given its apparent environmental leadership on a number of fronts."
And the reason for this groundbreaking drop? The replacement of one of last year's key inputs of the ranking--a reputation score--with a "disclosure" score. So we can't trust the sustainability community to weigh in accurately on how green they think a company is?
But wait! Not only that, we clearly can't trust the data crunchers themselves:
"We also learned that [Nike's] footprint is slightly larger than we were aware, as they outsource more than we knew before."
