Andrea Moffat interacts with lots of people in her job as director of corporate outreach for Ceres, a Boston-based network of investment funds and public-interest groups that promotes environmentally conscious policies in the business world. It might be the chief executive who discusses "green" issues with Moffat at one company, the head of investor relations at another, and the vice president of corporate responsibility at a third.

One senior position, though, remains something of a mystery to her. "I don't think I've ever sat down with a CIO," she says. "Do most large companies have one?"

We've come a long way since that early article on Green IT in 2006. Companies are buying into the idea that green is the color of money, even if there is a lot of greenwashing going on.

It's smart to be wary of the hype, but there's nothing wrong with doing good while doing well.
