Shopping online is one of the great luxuries of modern life and it has its environmental benefits. It keeps us from using our cars and, in the case of online-only stores, removes the need for energy-demanding, brick-and-mortar stores. But when you factor in the fuel-using, emission-producing trucks that deliver the products, it becomes clear that online shopping has its environmental cost. Luckily, delivery companies are starting to look for solutions.
UPS announced yesterday that it will be the first delivery company to use hydraulic hybrid vehicles (HHVs), a diesel hybrid technology that replaces the conventional drivetrain and transmission with a hydraulic propulsion system. Hydraulic pumps and hydraulic storage tanks capture and store energy and the diesel engine is used to periodically recharge pressure in the propulsion system.
The company began testing the EPA-developed technology two years ago on Detroit routes with significant results. The vehicles achieved a 45-50 percent increase in fuel economy compared to the conventional diesel trucks and the company believes that the same results, plus a 30 percent reduction in CO2, are possible in daily use. The first HHVs will be deployed in early 2009 in Minneapolis, with more following in 2010.
DHL is also planning to reduce their footprint. The company announced earlier this month that it was setting up a clean technology incubation unit that will fund innovative startups capable of helping them cut emissions. The company has set a target of reducing emissions by 30 percent by 2030.
