CATF argues that EPA's lifecycle analyses are flawed by relying on hypothetical 2022 production scenarios and ignoring current indirect land use change (ILUC) and the 'global rebound effect.' The document claims that cumulative GHG emissions from corn ethanol produced between 2010 and 2015 are 28% higher than those from gasoline. Furthermore, it states that the RFS contributes to global food insecurity by diverting crops and driving land conversion in tropical countries. CATF suggests transitioning to zero-carbon mobility fuels, such as ammonia, electricity, and synthetic hydrocarbons, rather than relying on biofuels.","ai_generated":true,"unit":"catf-000487#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"The RFS is not reducing greenhouse gas emissions below the levels of baseline petroleum-derived fuels.
