Going green has become a matter of necessity for companies whose  business involves driving. Consumer shipping businesses like UPS and  FedEx may not be the greenest of the green—Climate Counts gives them scores of 39 and 28 out of 100 respectively—but they’ve  recently begun deploying innovative strategies that will certainly  begin reducing their carbon dioxide emissions and can serve as a model  for other commercial shippers trying to stay afloat by using less gas.

Trucks can waste a lot of gas idling  while waiting for a left turn. At the beginning of 2007, UPS therefore  eliminated all left turns from delivery routes, and has so far reduced  over 30 million miles from their routes. This has saved 3 million gallons of gas and 32,000 metric tons of CO2—the equivalent of removing 5,300 passenger cars from the road for a year.

Compressed Natural Gas Delivery Trucks: UPS has deployed over 800 delivery trucks across the United States that run on compressed natural gas. While the  trucks look just like the diesel-guzzlers in UPS’ fleet, they release 20 percent fewer emissions and improve fuel economy by 10 percent.

Hybrid Electric Trucks: FedEx, in cooperation with Eaton  Corp. and Environmental Defense, has begun to incorporate hybrid  electric medium-duty trucks into its fleet. There may only be about 200  of them so far, but these vehicles can travel 57 percent farther than other medium-duty trucks per gallon, and create 65 percent fewer emissions and 96 percent less soot.

Fuel-Efficient Tires: More friction on tires means less fuel economy. That’s why FedEx and UPS have begun using wider, "fuel-efficient" tires that create less friction with the road. These tires allow for more  miles per gallon of diesel for the truck, thereby reducing emissions  and costs.

GPS: It may seem like an easy solution, but companies like  UPS and FedEx have seen their driving miles drop precipitously since  making GPS standard in every truck. Not only do deliveries arrive on  time when drivers don’t get lost—they burn less fuel when they’re not  driving around in circles.

Better Planning: Better technology and some simple forward  planning have allowed UPS and FedEx to save a lot of gas, as well. They  put newer, more fuel-efficient trucks on the longest routes, saving  older trucks for shorter drives. They also have systems for where to  put the heaviest packages so that they don’t place too large a burden  on the trucks; heavy loads are one of the biggest factors contributing  to poor fuel efficiency.

The environment may not be at the forefront of shipping companies’  minds as they try to boost their fuel efficiency, but it’s definitely  helping.

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
