Advanced Clean Cars combines the control of smog-causing (criteria) pollutants and greenhouse gas (GHG) emissions into a single coordinated package of regulations: the Low-Emission Vehicle regulation for criteria and GHG emissions and a technology forcing regulation for zero-emission vehicles (ZEV) that contributes to both types of emission reductions. The goal of the program is to guide the development of environmentally advanced cars that will continue to deliver the performance, utility and safety car owners have come to expect.
