Low carbon fuel standards, such as the Federal Renewable Fuel Standard and the California Low Carbon Fuel Standard, are major U.S. programs for reducing greenhouse gas (GHG) emissions from transportation fuels. These standards rely on life cycle assessment (LCA) as a tool to estimate fuel GHG emissions. However, current LCAs differ notably in how they are implemented, with disagreements pertaining to data quality, modeling approaches, and key assumptions. This methodological assessment aims to develop a reliable and coherent approach for applying LCA to low carbon fuel standards.
