From 1st- to 2nd-Generation Biofuel Technologies

The current debate over biofuels produced from food crops has pinned a lot of hope on “2nd-generation biofuels” produced from crop and forest residues and from non-food energy crops. This report, produced jointly with IEA Bioenergy, examines current state-of-the-art biofuel technologies as well as the challenges for 2nd-generation biofuel technologies. It evaluates their costs and considers policies to support their development and deployment.
