From press release:

Biofuels are getting a lot of attention as a way to slow global warming. But not all biofuels are created equal. Whether they help the environment depends on how they are produced. A new Environmental Defense report recommends polices that will ensure that renewable fuels live up to their promise. Specifically, our study shows that we need:

• a low-carbon fuel standard to spur production of biofuels with low greenhouse gas emissions and
• better protections for water and land resources that are vulnerable to increasing production of biofuel feedstocks.
