Abstract
California should adopt a phased supply chain accountability framework for electric vehicles sold in the state, combining the immediate implementation of a voluntary Fair Trade Decal program with the mandatory adoption of COFFEE (Corporate Operations Free From Environmental Evil) Standards based on CAFÉ standards, by 2035. This thesis identifies a critical gap in U.S. EV policy: current federal legislation regulates where batteries are sourced but not how cleanly or ethically they are produced. The consequences of this regulatory gap are severe, with emissions simply shifting further down the supply chain rather than being eliminated, child labor and indigenous displacement going entirely unaddressed, and consumers unknowingly contributing to significant environmental and social harm through the purchase of vehicles marketed as zero-emission. With the federal government actively dismantling EV protections and challenging California's regulatory authority, state-level action is both urgent and necessary.
