Biofuels - Worse than oil ?

Discovery News
"Clearing raw land to produce biofuels actually contributes to global warming by emitting large amounts of greenhouse gases into the atmosphere, researchers have warned.

Carbon dioxide (CO2) emissions from new croplands carved into rainforests, savannas, wetlands or grasslands would easily surpass the overall amount of CO2 emissions reduced through the use of biofuels, according to a report in the Feb. 8 edition of Science."

"...crops used in the production of biofuels -- creates a "biofuel carbon debt" by releasing 17 to 420 times as much CO2 into the atmosphere as the greenhouse gas reductions which the biofuels provide by displacing fossil fuels."

"The researchers calculated that in Indonesia, where wetlands are being converted to grow palm oil to produce biofuels, it will take 423 years before biofuel CO2 emission savings would repay the carbon debt caused by the land conversion."
