Promoting Responsible Growth of Biofuels (1 of 4) 1. Avoid “One-Size-Fits-All” Approach – Maximize usage of local/regional biomass resources – Minimize transportation of feedstocks – Expand diversity of feedstocks, processes, and products – There is no single best technology • Match technology with available feedstock • Integrate technologies – biorefinery concept 20
Promoting Responsible Growth of Biofuels (2 of 4) 2. Emphasize Sustainability of Biofuels – Life-cycle assessments (LCA) are very important • Must be improved/expanded • Consider both direct and indirect effects • Consider energy, GHG, environ., and ecological impacts • Develop common metrics that accurately reflect true impacts – Minimize tradeoff between food and fuel. Consider 1 st generation biofuels as temporary transition to 2 nd generation – Economic sustainability is also important Source: CEC Report 600-2007-004-Rev., August 2007 21
