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. Formaldehyde emissions did not show a statistically significant effect. Durbin, Kent C. 2023.128836.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars. Appendix D: Vehicle Driving Statistics. Conclusions.
