This report is a comprehensive response to 2007 Washington State legislation (HB 1303) that tasked Washington State University to 1) analyze the types and corresponding amounts of biofuel in the state and 2) recommend viable incentive programs to promote biofuel market development. Inside you will find policy recommendations based on analysis of a broad set of policy options, including renewable fuel standards and subsidies, carbon taxes, as well as approaches to support research, implementation of new technologies, and creation of infrastructure.
