Researchers find consumers compensate for fuel-efficient car by buying bigger second vehicle; losing 60% of fuel economy savings

Green Car Congress

An analysis by a team from the University of California, Davis, MIT and Yale suggests that households that buy a fuel-efficient vehicle tend to compensate for that purchase by buying a bigger, more powerful second vehicle. This unintended effect could erode goals of fuel economy standard policies by up to 60%.

Study urges tougher target for California LCFS; up to 26% by 2030 under high performance scenario

Green Car Congress

California can reduce carbon emissions by more than 70 million metric tons by 2030—akin to taking 15 million gasoline-powered cars off the road in one year—by adopting a higher target for its Low Carbon Fuel Standard (LCFS), according to an analysis released by the UK-based research firm Cerulogy.

NREL report on electric bus demo at Foothill Transit finds Proterra fuel economy >8x higher than CNG on same line

Green Car Congress

A team from the National Renewable Energy Laboratory (NREL) has released the second report summarizing the results of the battery-electric bus (BEB) demonstration underway at Foothill Transit in California. The CNG buses had an average fuel economy of 3.89 kWh per mile—17.35 miles per diesel gallon equivalent (mpdge).

California ARB awards $7M for ultra-low NOx heavy-duty diesel truck demo project with Achates opposed-piston engines

Green Car Congress

The California Air Resource Board (CARB) is awarding $7 million to CALSTART to develop a Class 8 truck that will achieve a 90% reduction in NO x along with a 15-20% fuel efficiency improvement. California’s ultra-low NO x emissions standard is 0.02 That will enable us to meet ultra-low NO x tailpipe standards.
