Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). Emissions are represented in 12 km resolution grids. Click to enlarge.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

The question of electricity costs vs. health and environmental cost is important to ask everywhere, Michalek said. Stacked bars show the change in generation cost combined with the median damages by pollutant assuming the 2010 social cost of carbon given by the Office of Management and Budget ($31 in $2010).

Researchers find Nissan LEAF creates less CO2 than Toyota Prius hybrid in west US and Texas, but more in N. Midwest

Green Car Congress

Regionally specific lifecycle CO 2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) in the US can vary widely based on grid emission factors (i.e., Under some conditions, the battery electric Nissan LEAF can produce higher emissions than a Toyota Prius hybrid.

We Need More Than Just Electric Vehicles

Cars That Think

The total cost of purchasing and driving one—the cost of ownership—has fallen nearly to parity with a typical gasoline-fueled car. With all this, consumers and policymakers alike are hopeful that society will soon greatly reduce its carbon emissions by replacing today’s cars with electric vehicles. EVs have finally come of age.
