Costco to Open 40-Pump Gas Station in Mission Viejo Amid California's Zero-Emission Vehicle Mandate

Costco plans to open a 40-pump gas station in Mission Viejo, California, in summer 2026, despite state regulations mandating zero-emission vehicles by 2035. The gas station will be the largest in the U.S., with a larger 240-pump station planned for Honolulu in 2027. The contrast between the gas station's opening and California's push for fossil fuel extinction reflects consumer preferences for traditional vehicles.
