Study Shows Ethanol Produces More CO2 Emissions Than Gasoline
2014-05-02 20:22:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: A Northwestern University study by an economist and a chemist reports that when fuel prices drove residents of So Paulo, Brazil, to mostly switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20 percent. At the same time, nitric oxide and carbon monoxide concentrations tended to go up. The four-year study is the first real-world trial looking at the effects of human behavior at the pump on urban air pollution. This empirical analysis of atmospheric pollutants,...

Thats exactly what a new government-funded study is saying in an analysis of cellulostic ethanol fuel made from byproducts like the leftovers from growing corn. The study suggests that while ethanol might cut emissions in the long term, in the short term, it actually produces 7 percent more emissions than gasoline. That means it cant meet the emissions targets and...

That rule, called "RFS Pathways II and Amendments to the Renewable Fuel Standard,"...
