UAI commissions study to see if corn-based ethanol not getting all the green credit it deserves

In Washington, a new study is underway to determine whether corn-based ethanol makes a larger contribution to the reduction of GHG emissions than it is currently receiving credit. The Urban Air Initiative commissioned a study with Transport Energy Strategies to look at the impact ethanol has on carbon reduction in the gasoline itself.

Current modeling regarding ethanol and GHG emissions by DOE’s GREET model focus on how ethanol is produced, how it gets from the field to the tank. However, UAI contends that no one has considered the GHG impact of ethanol from the fuel tank to the tailpipe. This is where UAI proposes corn ethanol warrants additional credit for reducing GHG emissions.
