Oops.  Accounting error seriously overestimates benefits of biofuels.  

The European Union is overestimating the reductions in greenhouse gas emissions achieved through reliance on biofuels as a result of a “serious accounting error,” according to a draft opinion by an influential committee of 19 scientists and academics.

The European Environment Agency Scientific Committee writes that the role of energy from crops like biofuels in curbing warming gases should be measured by how much additional carbon dioxide such crops absorb beyond what would have been absorbed anyway by existing fields, forests and grasslands.

Instead, the European Union has been “double counting” some of the savings, according to the draft opinion, which was prepared by the committee in May and viewed this week by The International Herald Tribune and The New York Times.

The committee said that the error had crept into European Union regulations because of a “misapplication of the original guidance” under the United Nations Framework Convention on Climate Change.

“The potential consequences of this bioenergy accounting error are immense since it assumes that all burning of biomass does not add carbon to the air,” the committee wrote.

Duh.  This has been a known fact to about everyone else, as most independent studies not done by a corn-state university have found ethanol to have, at best, zero utility in reducing atmospheric CO2.

It is worth noting that the EU would likely have never made this admission had it solely been under the pressure of skeptics, for whom this is just one of a long list of fairly obvious errors in climate-related science.  But several years ago, environmental groups jumped on the skeptic bandwagon opposing ethanol, both for its lack of efficacy in reducing emissions as well as the impact of increasing ethanol product on land use and food prices.
