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.

Great links. The first one was very informative. I found it interesting that they also looked into who could purchase the switchgrass and for what reason.
