The California Air Resources Board has revealed regulation­s aimed to reduce criteria and greenhouse gas emissions from both light and medium-duty vehicles beyond the 2025 model year. As for the light-duty, low emission vehicle (LEV) standards, the proposed changes include a 0.030 g/mile NMOG+NOX fleet average for nonzero emission vehicles (ZEV), the addition of cleaner emission certificat­ion bins, a phase-in of 3 mg/mile particulat­e matter (on US06 cycle) standard, and new coldstart emission requiremen­ts. The biggest concerns on cold-start emissions include controllin­g early drive-away emissions and regulating aggressive driving cold-start emissions for plug-in hybrid vehicles.
