The summary in the new report also states, “Increasing bioenergy crop cultivation poses risks to ecosystems and biodiversity” (WGIII).

The report lists many potential negative risks of development, such as direct conflicts between land for fuels and land for food, other land-use changes, water scarcity, loss of biodiversity and nitrogen pollution through the excessive use of fertilizers (Scientific American).

The International Institute for Sustainable Development was not so diplomatic, and estimates that the CO2 and climate benefits from replacing petroleum fuels with biofuels like ethanol are basically zero (IISD). They claim that it would be almost 100 times more effective, and much less costly, to significantly reduce vehicle emissions through more stringent standards, and to increase CAFE standards on all cars and light trucks to over 40 miles per gallon as was done in Japan just a few years ago.
