Statutory requirements for foundation model developers to report embodied silicon lifecycle emissions and megawatt-hour energy consumption for training runs.
California SB 253 (the Climate Corporate Data Accountability Act) and the EU CSDD Directive require large technology enterprises to publicly disclose annual Scope 1, Scope 2, and Scope 3 greenhouse gas emissions. For artificial intelligence developers, Scope 3 encompasses upstream semiconductor fabrication emissions and cloud datacenter power consumption during frontier model pre-training runs.
