Trucks Won't Be Fuming
The EPA has developed an upgrade kit that reduces fuel consumption and emissions by up to 20 percent.The SmartWay Upgrade Kits include technologies that reduce engine idling, improve aerodynamics and devices that treat exhaust to reduce emissions.
The EPA estimates that if trucks nationwide adopt the technology, they could save more than 3.3 billion gallons of diesel and 66 million metric tons of carbon dioxide emissions. Adoption shouldn't be much of a concern because the fuel savings will payback the cost of the upgrades within three years.
Trucks are an integral part of our infrastructure (since we gave up on expanding rail lines years ago) so upgrading these vehicles will probably do more to reduce pollution than all of the hybrids.
