...could end up increasing global greenhouse-gas emissions instead of reducing them. In the second paper, another team of researchers led by Tim Searchinger of Princeton University uncovered a potentially damaging flaw in the way carbon emissions from bioenergy are calculated under the Kyoto Protocol and in the carbon cap-and-trade bill currently being debated in Congress. If that error in calculation goes unfixed, a future increase in biofuel use could end up backfiring and derailing efforts to control global warming, according to the paper. "Biofuels can be an important part of the portfolio of climate-change activities," says...
...that come from using biofuels. CO2 emissions resulting from deforestation or other changes in the way we use land are not evaluated at all. The result is a huge, if accidental error in the existing global carbon accounting system - and one that now stands to be repeated in the cap-and-trade bill up for debate in Congress. "It's a very, very large loophole," says Searchinger, who had done pioneering work on problems of biofuels. "We're just effectively ignoring what happens on land."

Given how limited the impact of the Kyoto Protocol has been, the effects of that error have been modest so far. But if the U.S. adopts a cap-and-trade system with the same mistake, or if the world agrees to a truly global successor to Kyoto, the blowback could be enormous. As long as biofuels are incorrectly treated as 100% carbon neutral, they'll represent an economical way for companies to offset their greenhouse-gas emissions and comply with a tightening carbon cap. One study estimates that if the world were to meet a 50% "cut" in global greenhouse...
...greenhouse gases should get credit for those cuts. But politics will be another matter - the biofuel industry already has a lot of weight, especially in the U.S., where environmentalists need the votes of rural and Midwestern representatives in Congress if they are to have any hope of passing a cap-and-trade bill. Challenging the biofuel loophole could effectively scuttle cap-and-trade...
Facing a fourth-and-23 at the Lafayette 47, Winters threw up a desperation heave to the endzone. Improbably, the ball fell into the waiting hands of Lorditch. The Crimson converted the two-point conversion to cap off a memorable scoring effort in an otherwise forgettable game...
