Trust the government and their experts though.
"It is important to note that biofuel production and consumption, in and of itself, will not reduce GHG or conventional pollutant emissions, lessen petroleum imports, or alleviate pressure on exhaustible resources."
I.e., what the government claims it to be.
Hence my sarcastic comment about trusting the government and its "experts".
