Biofuels have direct, fuel-cycle GHG emissions that are typically 30-90% lower than those for gasoline or diesel fuels. However, since for some biofuels indirect emissions-including from land use change-can lead to greater total emissions than when using petroleum products, policy support needs to be considered on a case by case basis.
The IPCC has released a finalized draft of its Working Group III report. Sourced from Forbes, their analysis: that ethanol is worse than petroleum. The Working Group itself managed to say... Well, after a quick read-through of chapter 8, it appears they managed to keep any actual meaning occluded by a thick screen of political double-speak. So, I guess they said whatever you would like them to have said since nobody can prove any different.

On the other hand, this isn't the first study that indicated that Ethanol increases net energy cost , and decreases mileage while increasing pollution, and increasing food costs.
So regardless how they want to word it, the story is not new.
No, you are mistaken. I've always had this sig.
