CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). The vehicle test matrix had provisions for five vehicles on each emissions standards category (i.e.,

Fraunhofer ISI/ICCT analysis of PHEV data finds real-world CO2 emissions 2-4x higher than official values

Green Car Congress

A new analysis of the real-world usage of more than 100,000 plug-in hybrid electric vehicles shows a large deviation between on-road CO 2 emissions and fuel efficiency and the official vehicle type-approval values. Patrick Plötz, Coordinator of the Business Unit Energy Economy at Fraunhofer ISI and lead author of the study.

UC Davis researcher finds ride-hailing EVs offer triple the emissions benefits of a personally owned EV

Green Car Congress

The study’s analysis showed those concerns are overstated, noting it found no statistical difference between the two technologies for ride-hailing companies. While the data was collected in pre-pandemic times, the results also can hold implications for delivery drivers and the gig economy, where drivers make multiple trips throughout the day.

California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
