In an automotive sector strained by recession, lay-offs, bankruptcies, the credit crunch and recalls, one bright spot over the last year has been the move among corporations to more fuel efficient fleets.

Poland Springs Water, a brand of Nestle Waters, has been greening its fleet since 2007, and seeing big savings as a result. It all started when Chris McKenna moved from warehouse manager to fleet manager at Poland Springs. He had been using biodiesel in the warehouse yard trucks and thought it might be worth testing for the fleet.

UPS shed 30 million miles from its delivery routes in 2007, and three million gallons of gasoline, after drivers cut back on their left-hand turns.

"The only left turn you make is to come home," says Dan McMackin, a former UPS driver who is now a company spokesman.

Don’t knock life in the right lane until you try it.

For UPS, it produced a giant cut in carbon dioxide emissions of 32,000 metric tons. That’s equivalent to removing 5,300 passenger cars from the roads for an entire year.
