The Role of Oil and Gas in Pomona's Economy
Pomona is a crossroads city. Interstate 10, State Route 57, State Route 60, and State Route 71 all pass through or near it, and freight moves constantly between Los Angeles ports and the Inland Empire's massive warehouse district. That traffic depends on a dependable supply of gasoline, diesel, and other petroleum products. At the same time, thousands of homes, restaurants, and industrial facilities across the Pomona Valley rely on natural gas for heating, cooking, and manufacturing processes.
While California is steadily transitioning toward cleaner fuels, oil and gas companies remain essential to daily life and commerce in Pomona. Many of these firms are also investing in renewable diesel, hydrogen, and renewable natural gas, reflecting the state's evolving energy policy.
