There were 90 respected scientist who seem to come seeking any arguable biofuel development loopholes as also being a contributor and needing to 'slack off' policy in USA on biofuels. The biofuel worldwide has eyes on this:
Here is what they say and what we say respectively, readers and audience can judge. The issue is 'backed' seem to me personally by big cats if possible (who knows?).
Here is what they wrote to the speaker Nancy Pelosi:

Dear Speaker Pelosi and Majority Leader Senator Reid,
We write to bring to your attention the importance of accurately accounting for carbon dioxide emissions from bioenergy in any law or regulation designed to reduce greenhouse gas emissions from energy use. Proper accounting can enable bioenergy to contribute to greenhouse gas reductions; improper accounting can lead to increases in greenhouse gas emissions both domestically and internationally.
Replacement of fossil fuels with bioenergy does not directly stop carbon dioxide emissions from tailpipes or smokestacks. Although fossil fuel emissions are reduced or eliminated, the combustion of biomass replaces fossil emissions with its own emissions (which may even be higher per unit of energy because of the lower energy to carbon ratio of biomass). Bioenergy can reduce atmospheric carbon dioxide if land and plants are managed to take up additional carbon dioxide beyond what they would absorb without bioenergy. Alternatively, bioenergy can use some vegetative residues that would otherwise decompose and release carbon to the atmosphere rapidly. Whether land and plants sequester additional carbon to offset emissions from burning the biomass depends on changes both in the rates of plant growth and in the carbon storage in plants and soils. For example, planting fast-growing energy crops on otherwise unproductive land leads to additional carbon absorption by plants that offsets emissions from their use for energy without displacing carbon storage in plants and soils. On the other hand, clearing or cutting forests for energy, either to burn trees directly in power plants or to replace forests with bioenergy crops, has the net effect of releasing otherwise sequestered carbon into the atmosphere, just like the extraction and burning of fossil fuels. That creates a carbon debt, may reduce ongoing carbon uptake by the forest, and as a result may increase net greenhouse gas emissions for an extended time period and thereby undercut greenhouse gas reductions needed over the next several decades1
Many international treaties and domestic laws and bills account for bioenergy incorrectly by treating all bioenergy as causing a 100% reduction in emissions regardless of the source of the biomass. They perpetuate this error by exempting carbon dioxide from bioenergy from national emissions limits or from domestic requirements to hold allowances for energy emissions. Most renewable energy standards for electric utilities have the same effect because bioenergy is viewed as a renewable energy even when the biomass does not eliminate or even reduce greenhouse gas emissions. This general approach .

appears to be based on a misunderstanding of IPCC guidance2
U.S. laws will also influence world treatment of bioenergy. A number of studies in distinguished journals have estimated that globally improper accounting of bioenergy could lead to large-scale clearing of the world’s forests. Under some scenarios, this approach could eliminate most of the expected greenhouse gas reductions during the next several decades.

The lesson is that any legal measure to reduce greenhouse gas emissions must include a system to differentiate emissions from bioenergy based on the source of the biomass. The National Academy of Sciences has estimated significant potential energy production from the right sources of biomass.

Sincerely, . Proper accounting will provide incentives for these sources of bioenergy.

Here is what we say: Biofuel/biofuel digest-worldwide.
Reaction from the Natural Resources Defense Council
Nathanael Greene, of the Natural Resources Defense Council, commented: “Today a group of leading scientists from across the country sent a letter to congressional leaders and Obama officials urging them to carefully count the carbon from biomass burned for energy as part of a comprehensive climate bill or any other legislation or regulation.
The American Power Act (APA) proposed by Senators Kerry and Lieberman provides a solid framework for reducing our global warming pollution and investing in a cleaner economy. Unfortunately, as proposed, the bill would turn a blind eye towards emissions from biomass combustion, threatening to significantly undermine the bills carbon reduction goals. (For some basic thoughts on how the bill should be amended see this fact sheet put out by NRDC and other groups after the House climate bill passed.)
I did a little video late last year explaining the fundamental flaw in the approach that the APA would take. The letter from the scientists puts it clearly: Replacement of fossil fuels with bioenergy does not directly stop carbon dioxide emissions from tailpipes or smokestacks. Although fossil fuel emissions are reduced or eliminated, the combustion of biomass replaces fossil emissions with its own emissions (which may even be higher per unit of energy because of the lower energy to carbon ratio of biomass). Bioenergy can reduce atmospheric carbon dioxide if land and plants are managed to take up additional carbon dioxide beyond what they would absorb without bioenergy…. On the other hand, clearing or cutting forests for energy, either to burn trees directly in power plants or to replace forests with bioenergy crops, has the net effect of releasing otherwise sequestered carbon into the atmosphere, just like the extraction and burning of fossil fuels. That creates a carbon debt, may reduce ongoing carbon uptake by the forest, and as a result may increase net greenhouse gas emissions for an extended time period and thereby undercut greenhouse gas reductions needed over the next several decades.
The Digest’s take: ”Round up the Usual Suspects.”
The letter was signed by seven members of the National Academy of Sciences and a Nobel Peace Prize co-laureate. and should be taken seriously as a point of view in science, and certainly as a political act.
This letter represents scientists, but does it represent science? Imagine what a country the United States would have turned out to be if every US state ratified a different Constitution.
It was primarily signed by biologists and ecologists and did not include leading scientists noted in the development of bioenergy technologies — such as George Church, Chris Somerville, Bruce Dale, Lee Lynd, or Charles Wyman to cite a few examples. A letter signed by a more inclusive group of scientists would have done more to dispel the sense that this letter represents a narrowly-held view within the scientific community, rather than consensus, and consensus must be the basis of any renewable energy policy which would provide any of the benefits of policy stability that renewables as a sector unequivocally require.
Give me Liberty or Give me Death: Give Us Unity or We’ll Face Dearth
The Digest urgently calls on its friends in the scientific community, through the National Academy of Sciences, or other appropriate vehicles, to develop a point of view which can be generally said to be representative of a broad scientific consensus. We have seen what a lack of consensus can do to side-track the discussion of climate change.
Whatever the consensus is, let the chips fall where they may.
Renewable energy needs stability, not a series of partisan letters from open side of the table that can be expected to be answered with a parallel set of letters from the other. That’s ping-pong, not policy, and the time for games has long since passed.
Here at Biofuel, we believe that we are capable to go green and in one big leap will support the world go green and efficiently support and supply the needed commodity The fuel...that is Biofuel for blend or pure! Beside we are cleaning the tons of trash laid down by 200 years of fossil fuel. A group of scientist from that corner of the world cannot ultimately turn down biofuel..we further emphasis that panel of scientists from all arena will have to give in their grip on Biofuel. Besides, Biofuel is a wheel that is at your disposal to steer the course unlike fossil fuel.

I am amazed at the fossil thinking of these “scientists.”
1) There is a fundamental difference to the carbon content of the atmosphere between using fossil carbon and biogenic carbon sources. Fossil carbon combustion adds GHG that was never part of the carbon cycle before – carbon positive. Biogenic carbon combustion simply recycles that which is already in the atmosphere – carbon neutral.
2) GHG emissions is only one scientific reason for replacing fossil fuels with biogenic. Others include: fossil is not renewable (biogenic is); fossil distillation is getting more toxic (biogenic is getting cleaner); direct fossil land and water use change is severely impacting ecology (i.e., oilspills and tar sands); bioenergy conversion facilities will provide env. clean-up and funding for timberland thinnings, hurricane knockdown, flood demolition, invasive species control, landfill mitigation, etc.
This doesn’t even begin to cover the environment, pollution, and biodiversity costs of present and future strategic commodity resource wars like Iraq.Someone needs to rethink their carbon accounting.
