UC Riverside study finds emissions benefits for E15 blend in California

Green Car Congress

A study by a team from UC Riverside has assessed the potential of increasing ethanol content in California reformulated gasoline (CaRFG) by investigating the exhaust emissions from a fleet of 20 Tier 3 light-duty vehicles. Acetaldehyde and ethanol emissions responded strongly with ethanol across the fleet of 20 vehicles.

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. Statistically, private users of vehicles in Germany re-charge their plug-in hybrid vehicle only on three out of four days.
