Truck Efficiency and GHG Reduction Opportunities in the Canadian Truck Fleet
Fuel-efficiency devices such as retrofittable aerodynamic technologies, fuel-efficient tires, and auxiliary power units can effectively offset engine-efficiency losses resulting from the 2002 and 2007 Environment Canada and U.S. EPA emissions regulations, while reducing greenhouse gas (GHG) emissions significantly. To identify which fuel-saving devices are most effective, consistent, clear involvement from…
Dust to Dust’s Assumptions About the Prius and the Hummer
In 2007, CNW published a study called Dust to Dust which reports the results of a life cycle analysis that compared the environmental impact of a Toyota Prius and a Hummer H3. The report claims that the Prius has a greater environmental impact than the H3. In response to this…
Profitable GHG Reduction Through Fuel Economy
This presentation outlines practical ways that Class-8 truck fleets can realize significant fuel savings and increased profits through efficiency techniques. Focusing on components that save fuel and providing case studies that have capitalized on these opportunities, RMI’s researchers demonstrate how a 25% fuel economy improvement is possible using existing technologies…
Letter to NHTSA on Revised Light Truck CAFE Standards
This letter was written by Amory Lovins in 2005 and sent to the National Highway Traffic Safety Administration. In the letter, Lovins commends the NHTSA for its 2005 adoption of CAFE standards based on size rather than weight. Size-based standards incentivize manufacturers to use lighter materials that improve the efficiency…
Legislative Options to Improve Transportation Efficiency
Traditional policy prescriptions for transportation efficiency have been largely misguided. With smarter legislation, the auto industry can restore competitiveness, boost profits, and displace oil use. The economic burden of high oil prices, concerns of supply and security, and environmental impact are justifiable reasons for state governments to act now. This…
