Study finds air pollution caused by corn production increases mortality rate in US

Green Car Congress

The paper, published in Nature Sustainability , presents how researchers have estimated for the first time the health damages caused by corn production using detailed information on pollution emissions, pollution transport by wind, and human exposure to increased air pollution levels. a, Absolute mortality. per bushel (56.5

Researchers say fuel market rebound effect can result in increased GHG emissions under RFS2; suggest taxes over mandates

Green Car Congress

However, argues a team from the University of Minnesota in an open-access paper published in the journal Energy Policy , once the “fuel market rebound effect” is factored in, RFS2 actually increases GHG emissions when all fuel GHG intensity targets specified under the act are met. for its analysis. —Hill et al. 2016.07.035.

University of Minnesota Study Finds Cellulosic Ethanol Carries Lower Human Health Economic Costs Than Gasoline or Corn Ethanol

Green Car Congress

A new study by researchers at the University of Minnesota finds that cellulosic ethanol has fewer negative effects on human health because it emits smaller amounts of fine particulate matter. Jason Hill, lead author, resident fellow in the University of Minnesota’s Institute on the Environment. The public pays these costs.”

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). The researchers included a sixth pollutant, ammonia (NH 3 ).

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.

Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

A specific challenge would-be-conversions must face is that the NRC’s standards—both for atmospheric pollution and for the amount of radiological material a reactor can release—are much tighter than federal standards for coal plants.

Study: Reducing Future Transportation CO2 Emissions to Kyoto Protocol Levels Will Require Combination of Vehicle Technology and Smart Growth

Green Car Congress

A Georgia Tech City and Regional Planning study on climate change concludes that “smart growth” combined with the use of hybrid vehicle technology could reduce cities’ carbon dioxide (CO 2 ) emissions significantly by 2050.
