(2) Overlapping and ever-changing fuel emis-
sions standards, whether imposed by the Environ-
mental Protection Agency, the State of California, or 
through Corporate Average Fuel Economy regula-
tions, create long-term uncertainty for manufactur-
ers. 
(3) This fragmented regulatory environment sti-
fles innovation, disrupts supply chains, and burdens 
manufacturers and businesses, especially small and 
medium-sized auto suppliers. 
(4) Conflicting fuel emissions standards force 
manufacturers to comply with multiple sets of costly 
and inconsistent regulations, further reducing effi-
ciency and raising production costs, which are ulti-
mately passed onto the consumer. 
(5) 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 eco-
nomic freedom.
