Biofuels can’t get any respect these days. Science magazine (subs. req’d) recently published an article whose abstract reads, simply,
The carbon sequestered by restoring forests is greater than the emissions avoided by the use of the liquid biofuels.
The article, “Carbon Mitigation by Biofuels or by Saving and Restoring Forests?” notes:
Two issues need to be addressed before the efficacy of biofuels can be assessed: the net reduction in fossil carbon emissions (avoided emissions) arising from use of agriculturally derived biofuels and the effect of alternative land-use strategies on carbon stores in the biosphere.
