Sentences with phrase «emissions than corn»

Experiments in Quebec found that soybeans, a major legume oilseed crop in eastern Canada, produced lower nitrous oxide emissions than corn, the major cereal crop grown in the eastern region.

Not exact matches

«The study says it will be very hard to make a biofuel that has a better greenhouse gas impact than gasoline using corn residue,» which puts it in the same boat as corn - based ethanol, said David Tilman, a professor at the University of Minnesota who has done research on biofuels» emissions from the farm to the tailpipe.

A peer - reviewed study performed at the Energy Department's Argonne National Laboratory in 2012 found that biofuels made with corn residue were 95 per cent better than gasoline in greenhouse gas emissions.

Algae production consumes more energy, has higher greenhouse gas emissions and uses more water than other biofuel sources, like corn, switch grass and canola, Clarens and his colleagues found by using a statistical model to compare growth data of algae with conventional crops.

Emissions decreased as the proportion of soybeans in the diet increased, as soybeans require less nitrogen fertilization than corn grain.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

In what would certainly be a huge blow to the US» formidable corn - ethanol industry, the California Air Resources Board is readying a report that says ethanol is worse than oil in terms of greenhouse gas emissions.

An independent panel of academic scientists for the National Research Council of the National Academy of Sciences — reviewing the conflicting work of Searchinger, Wang and several others — concluded in a 2011 report that «corn - grain ethanol might not have lower [greenhouse gas emission] values than petroleum - based gasoline.»

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.

Focusing on the carbon emissions associated with tropical deforestation, it showed that converting rainforests or grasslands to corn, soybean, or palm oil biofuel production led to a carbon emissions increase — a «biofuel carbon debt» — that was at least 37 times greater than the annual reduction in greenhouse gases resulting from the shift from fossil fuels to biofuels.

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.

Other research has shown that several common biofuel feedstocks — including corn and rapeseed which have considerably lower yields than oil palm — also have high emissions from direct and indirect land use.

The EPA's experts determined that corn ethanol was only modestly better than gasoline when it came to carbon dioxide emissions.

There are more emissions from the total Corn Ethanol production sequence and use as an alternative and additive to fossil fuels than if ordinary fossil originated fuels were just used to do the job.

He pointed to findings that corn ethanol, which plays the largest role in meeting RFS mandates, emits more greenhouse gases than gasoline, and he said it is «confusing» for the Obama administration to push corn ethanol while it seeks to lower global greenhouse gas emissions at the Paris climate summit.

Far from having a substantial impact on reducing net emissions of GHG, Wolf says, European rapeseed oil - based diesel and U.S. corn - based ethanol have in fact only made small contributions - 13 % less than conventional diesel and 18 % less than petrol, respectively.

(Note that the study did not look at first generation biofuels made from tropical crops like sugarcane or sweet sorghum which reduce emissions far more than corn ethanol; for sugarcane ethanol, the reduction is as large as that of cellulosic biofuels, earlier post.)

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

The conversation keeps getting dragged away because the ethanol * program * has had lots of unintended effects (corn prices, food prices, etc.) You claim that raising fuel efficiency will do more than ethanol in terms of saving the environment, but take another step back and consider the easiest way to save the environment — taxing carbon emissions.

Using perennial bioenergy crops (e.g., switchgrass, silver grass, willow, eucalyptus) rather than annuals (e.g., corn) reduces emissions and raises carbon sequestration in soil.
