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. A baseline CaRFG E10 (10% ethanol by volume) fuel was splash-blended with denatured ethanol to create an E15 fuel.

New study finds gasoline stations vent up to 10x more benzene fumes than previously thought

Green Car Congress

A study led by environmental health scientists at Columbia University Mailman School of Public Health examined the release of vapors from gasoline station vent pipes, and found benzene emissions were 10 times higher than estimates used in setback regulations that determine how close schools, playgrounds, and parks can be to the facilities.

Study finds that environmental impact of corn-ethanol E85 is 23% to 33% higher than that of gasoline; environmental problem-shifting

Green Car Congress

Environmental impacts of gasoline and E85. In a similar way, the full breadth of impacts attributable to conventional gasoline production, such as natural resource consumption and hazardous pollutant emissions, must also be considered in order to make balanced comparisons to biofuels. Process flow diagrams for E85 and gasoline.

California ARB holding informational meeting on feasibility of measuring LEV III PM mass standards

Green Car Congress

The California Air Resources Board (ARB) will conduct a public meeting on 22 October to hear an update from ARB staff on the feasibility of measurement of LEV III particulate matter (PM) standards. PM emissions from light- and medium-duty vehicles are regulated by California’s Low-Emission Vehicle (LEV) regulations. Earlier post.)

Brazilian biofuels with LUC may have much higher non-GHG emissions than conventional gasoline and diesel

Green Car Congress

Comparisons of life-cycle emissions from LUC phase for (a) sugar cane ethanol and (b) soybean biodiesel. A paper on their work is published in the ACS journal Environmental Science & Technology. Even in the 100-year case, LUC emissions in CO and particulate matter are still higher than that of gasoline. Credit: ACS, Tsao et al.
