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.

I will have to disagree with this study.
I have noticed my emissions are much worse when I drink petroleum instead of ethanol!(not to mention the brutal hangovers!)
This is old news, and this study will change things about like all the similar studies have...not.
Until improvement and innovation take precedence over protecting entrenched business models, this will not change.
And this phenomenon is not confined to the 'energy industry', it is almost universal.
