In particular, the cited paper includes this:

    It’s always been pretty obvious that ethanol fuel is a way to greenwash gasoline cars while throwing more money to the corn industry. The only benefit is that it’s renewable (but the corn industry in its current state relies heavily on non-renewable petroleum products.)

    Always good to see the science though.
