Getting the Most Green Bang for Your Greenbacks

Many investors don't rank environmental concerns high on the list of metrics they consider when researching stocks, but it's likely more are coming around to the idea that the tides are changing. How the companies we consider investing in treat the planet is part of a major shift in the way many of us view the definition of solid, long-term management practices.

Of course, it's often difficult to know which companies do a bang-up job on earth-friendly initiatives, but here's one fertile resource: Newsweek recently released its Green Rankings 2012.

It's also been a force to reckon with for suppliers, blocking those that are connected to deforestation and illegal logging practices¬†.

The third-greenest company is Sprint-Nextel (NYSE: S  ) , with a Green Score of 77.5.

Financial company BlackRock (NYSE:
