Fortune Magazine is following what seems like every other magazine out there with its own "first-ever green edition." Among pages on Schwarzenegger's credentials and the new big business of clean technology, Fortune has put together a list of the top ten greenest mega-corps. While it is nice to see that some of these monster corporations have green credentials (each of the companies listed has between 5 and 380 thousand employees,) it can be difficult to make the big businesses of auto-making, aluminum refining, and tar-sand mining to sound environmental at all. Reading the list, it becomes obvious that there's only one way to measure green credentials from Fortune's perspective, and that is to compare each company to other companies in the same sector.
