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

Green Car Congress

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. This study highlighted the environmental impacts of corn ethanol in comparison with gasoline.

NREL review of E15 effects on MY2001 and later cars finds no meaningful differences with E10

Green Car Congress

The main conclusions of NREL’s analysis were: Several of the studies tested relatively large numbers of engines or vehicles, including the Coordinating Research Council’s (CRC) engine durability study (28 engines); the University of Minnesota’s in-use fleet study (80 vehicles); and the US DOE’s catalyst durability study (82 vehicles).

New study of emissions and health impacts from EVs in China, including massive e-bike fleet

Green Car Congress

The team found that using concentration rather than intake is suboptimal for health comparisons. The study used an intake-based, rather than concentration-based, risk assessment for primary PM 2.5. For example, they noted, comparing PM 2.5 are about equal between the two modes.
