UPS has already been using hybrid trucks in it's U.S. Green Fleet, now they are increasing their fleet - the company will go from 50 to 250 trucks on the road. UPS expects that the hybrid trucks will save the company 176,000 gallons of fuel a year and reduce CO2 emissions by 1,786 metric tons each year. The CO2 emissions are equivalent to taking 100 UPS trucks off the road for one year.  

Con-Way Truckload announced its new enterprise-wide sustainability initiative. By reducing its 2,700-tractor fleet maximum speed from 70 to 65 mph, the company could lessen its carbon emissions by 62 million pounds, equivalent to removing 6,300 cars from American highways. The company also expects an annual savings of 2.8 million gallons of diesel fuel. 

As gas prices continue to soar, some airlines have taken the unusual approach of increasing flight times by flying slower. Airlines have advised that the change is minimal and the longer flight time is absorbed into the extra time already built in for taxiing and traffic delays. However, the savings is in the millions for airlines. For instance, Southwest Airlines reports it will save $42 million in fuel this year by extending each flight by one to three minutes. 

In February, Virgin Atlantic proved to 200 journalists and millions of people that biofuel could be used in aviation by having a 747 take off with one of it's engines having a composition of 25% mixture of biofuel and standard kerosene jet fuel. The biofuel was a combination of coconut and babassu (Brazilian tree) oil. However, not all individuals were thrilled with this first. Some are concerned that growing crops for alternative fuels cuts into the availability of land for growing food.  

“There is a finite amount of land for food" stated Kate Horner, a climate and energy campaigner for Friends of the Earth, “and using it for the expanded production of fuel is driving deforestation, which accounts for one-fourth to one-third of our global emissions.”
