This research shows that on average, corn ethanol produces emissions 51 % lower than gasoline.

Not exact matches

An assessment paid for by DuPont said that the ethanol it will produce there could be more than 100 per cent better than gasoline in terms of greenhouse gas emissions.

«Corn - based ethanol, instead of producing a 20 percent savings [in greenhouse gas emissions], nearly doubles greenhouse emissions over 30 years and increases greenhouse gases for 167 years,» the researchers write.

Using corn to produce ethanol has driven up food prices in recent years, and converting forests and other areas into farmland to grow more corn for biofuels may well negate ethanol's improved greenhouse gas emissions (GHG).

The fuel, which supposedly produces less volatile organic compound (VOC) emissions than regular diesel fuel or ethanol, is being produced by RenTech in Rialto, California.

All such «life cycle» studies attempt to estimate all the carbon emissions created by producing and burning ethanol, including carbon released from soil by plowing and from fuel burned in planting, harvesting and refining.

And there was this: «By using a worldwide agricultural model to estimate emissions from land - use change,» Timothy Searchinger of Princeton and other researchers reported in 2008, «we found that corn - based ethanol, instead of producing a 20 percent savings, nearly doubles greenhouse emissions over 30 years and increases greenhouse gases for 167 years.»

It cited «plausible scenarios in which GHG [greenhouse gas] emissions from corn - grain ethanol are much higher than those of petroleum - based fuels,» and questioned the method by which EPA determined that ethanol would produce 21 percent less emissions.

California's LCFS also would have little or no impact on GHG emissions nationwide and would harm our nation's energy security by discouraging the use of Canadian crude oil — our nation's largest source of crude — and ethanol produced in the American Midwest.

They promote spending $ 22 billion just in federal money during FY - 2014 on climate change studies; costly solar projects of every description; wind turbines that blight scenic vistas and slaughter millions of birds and bats annually, while wind energy developers are exempted from endangered species and other environmental laws that apply to all other industries; and ethanol programs that require millions of acres of farmland and vast quantities of water, fertilizer, pesticides and fossil fuel energy to produce a gasoline additive that reduces mileage, harms engines, drives up food prices... and increases CO2 emissions.

A few recent studies still claim that corn ethanol produces fewer emissions than gasoline, but a careful look reveals that their methods don't properly account for land use change.

«The biofuels researcher Timothy Searchinger has calculated that once the massive release of greenhouse gases cause by converting grassland and rainforest into cropland is taken into account, introduction of biofuels produces increases in greenhouse emissions, the size of the rise being as much as a doubling for corn ethanol production,» Montford tells us.

However, Joe Romm pointed out that though «as a matter of science the deal is not optimal,» the end effect of this compromise is slight, noting that most of the corn ethanol produced under the 2007 energy bill was already grandfathered in and would not have to meet these emissions requirements.

Biofuels» Emissions Benefits Often Overstated Citing the study, Reuters reports that, «The OECD said that if Brazil's ethanol produced from sugar cane cuts greenhouse gas emissions by around 80 %, biofuels from other feedstocks in the United States, the EU or Canada tend to have a far lower environmentalEmissions Benefits Often Overstated Citing the study, Reuters reports that, «The OECD said that if Brazil's ethanol produced from sugar cane cuts greenhouse gas emissions by around 80 %, biofuels from other feedstocks in the United States, the EU or Canada tend to have a far lower environmentalemissions by around 80 %, biofuels from other feedstocks in the United States, the EU or Canada tend to have a far lower environmental benefit.

In passing the Act, Congress intended to replace 30 percent of petroleum vehicle fuel use with alternative fuels by 2010, through federal purchase of less polluting vehicles, and by harnessing the purchasing power of the federal government to spur the market for natural gas, propane, ethanol and electric vehicles, which produce less pollution and greenhouse gas emissions.

Alternative fueled vehicles are powered by natural gas, propane, ethanol, or electricity, which produce less pollution and greenhouse gas emissions than petroleum fueled vehicles.

Most ethanol produced in the United States is currently derived from corn, a relatively poor feedstock given its low yield and high fertilizer requirements which have been linked to water pollution, the expanded «dead zone» in the Gulf of Mexico, and significant greenhouse gas emissions.
