Corporate Culture...

Wal-Mart loves to go green if it will save the company green. The company has made several recent moves to reduce its environmental footprint while saving costs, and according to a recent Reuters article, Wal-Mart's trucking fleet leeds the way in these efforts.

Here's what they've done so far:

1. Trucks now carry less fuel. This keeps weight down, which makes the trucks more efficient.

2. They're using fuel-efficient tires. You can't go wrong there. (You can read more about fuel-efficient tires here.)

3. Wal-Mart has added controls that allow drivers to turn off cab engines while still keeping refrigeration systems running -- a major energy-saver. (Shorepower's Electrified Parking Spaces are another technology that helps cut down on use of diesel fuel when a vehicle is parked.)

In addition, Wal-Mart is looking to reduce the amount of packaging on its products by 5% over the next five years. Less packaging equals less weight and also means more product can fit in a truck, reducing the number of trucks needed.

All told, Wal-Mart expects these changes to save the company billions of dollars over the next five years alone.

And that, my friends, is a lot of green.
