Biofuel has become a Green’s owned dilemma, destroying rain forest for Palm Oil, destroying motor car engines, yet the original idea was to save carbon emissions, or at least be carbon neutral. Well, they sure got that agenda wrong too according to a new study:

Biofuels not as ‘green’ as many think
Go back to basics when calculating the greenhouse impact and carbon neutrality of biofuels, researchers urge
Statements about biofuels being carbon neutral should be taken with a grain of salt. This is according to researchers at the University of Michigan Energy Institute after completing a retrospective, national-scale evaluation of the environmental effect of substituting petroleum fuels with biofuels in the US. America’s biofuel use to date has in fact led to a net increase in carbon dioxide emissions, says lead author John DeCicco in Springer’s journal Climatic Change.
The use of liquid biofuels in the transport sector has expanded over the past decade in response to policies such as the US Renewable Fuel Standard (RFS) and California’s Low-Carbon Fuel Standard (LCFS). These policies are based on the belief that biofuels are inherently carbon neutral, meaning that only production-related greenhouse gas emissions need to be tallied when comparing them to fossil fuels.

A snippet from the author, DeCicco: […]
DeCicco’s team evaluated the data up to 2013, using the Annual Basis Carbon (ABC) accounting method he previously developed. It takes a circumscribed look at the changes in carbon flows directly associated with a vehicle-fuel system, and does not treat biofuels as inherently carbon neutral.
Instead, the ABC method tallies carbon dioxide emissions on the basis of chemistry in the specific locations where they occur. The system takes into account motor fuel consumption, fuel processing operations and resource inputs, including the use of cropland for biofuel feedstocks. Unlike lifecycle analysis, ABC accounting reflects the stock-and-flow nature of the carbon cycle, recognizing that changes in the atmospheric stock depend on both inflows and outflows.
DeCicco’s team found that the gains in carbon dioxide uptake by feedstock, such as corn, were enough to offset biofuel-related biogenic emissions by only 37 percent, rather than 100 percent, during the period 2005 to 2013.
“This shows that biofuel use fell well short of being carbon neutral even before considering process emissions,” says DeCicco. […]
It’s doubtful there will be much change in the US, because, cronyism :
EPA: The Ethanol Protection Agency
Maybe the initials “EPA” should stand for the Ethanol Protection Agency, as environmental protection seems just too costly and time consuming for the agency. The EPA recently admitted that it has not been in compliance with the 2007 law that requires the agency to study the environmental impact of the ethanol mandate and report its findings to Congress every three years. So far, envirofascist bureaucrats have only met the law’s requirements once in 2011. The EPA’s excuse is that it just doesn’t have enough funding or time and therefore has simply ignored the law.
According to the EPA’s inspector general, because the agency hasn’t been conducting the impact study, it hasn’t been able “to identify, consider, mitigate and make policymakers aware of any adverse impacts of renewable fuels.” The EPA now says it won’t have a fully completed study until at least 2024. Well, that’s good news if you’re a corn farmer, but not such good news for the environment or even other corn-dependent industries, as price of corn has increased.
Several recent independent environmental studies conclude that ethanol biofuels have had an overall negative effect on the environment from an increase of smog in cities to the amount of land, water and energy needed to produce ethanol when compared to that of gasoline. Combined with worse mileage and damage to small engines, ethanol has had the exact opposite effect of what it was touted to accomplish when it was initially mandated back in 2005. Yet there is no push by either Congress or the Obama administration to repeal or even question the ethanol mandate. And the agency tasked with protecting the environment seems too busy figuring out how to clean up its own environmental messes to care. Cronyism at its best.
