SEC. 1. Short title

• This Act may be cited as the Fuel Emissions Freedom Act.

SEC. 2. Findings

• Congress finds the following:
  • Fuel emissions regulations increase costs for consumers and manufacturers.
  • Overlapping and ever-changing fuel emissions standards, whether imposed by the Environmental Protection Agency, the State of California, or through Corporate Average Fuel Economy regulations, create long-term uncertainty for manufacturers.
  • This fragmented regulatory environment stifles innovation, disrupts supply chains, and burdens manufacturers and businesses, especially small and medium-sized auto suppliers.
  • Conflicting fuel emissions standards force manufacturers to comply with multiple sets of costly and inconsistent regulations, further reducing efficiency and raising production costs, which are ultimately passed onto the consumer.
  • Eliminating fuel emissions standards at the Federal and State level will help restore regulatory certainty, lower costs for families, and strengthen manufacturing in the United States to ensure economic freedom.
