Chevron warns California: Company says strict climate rules and Iran war could force refineries to close, sparking fuel shortages
Chevron’s global refining president warned California officials that stringent climate rules and global supply shocks, including the Iran war, could force the company to exit state refining within ten years, risking refinery closures, severe fuel shortages and higher gas prices.

What Chevron is saying
Andy Walz, Chevron’s Global Refining President, told state leaders that the current mix of costly regulation and tightening global supplies threatens operations and reliability. He warned that without policy changes, “They won’t have any refineries in 10 years,” and added, “Chevron will be gone in 10 years for sure. We won’t be able to make it” — Insurance Journal.
Walz highlighted practical risks such as jet fuel shortfalls at major airports and gasoline shortages in dense population centers, calling those outages “my worst fear.” He cautioned that refinery closures can be largely irreversible and would disproportionately impact vulnerable populations — reporting and commentary cited by Fox Business and Insurance Journal.
Supply strains and foreign reliance
Chevron points to international supply shocks as a key problem. California and West Coast markets often rely on refined fuels from Asia — a link that becomes risky if the Strait of Hormuz is blocked or if Asian refineries reduce exports. Chevron has reportedly rerouted Gulf Coast oil through the Panama Canal to offset West Coast shortfalls — Insurance Journal.
Walz described California’s reliance on imports as “a dangerous game” and urged state leaders to declare an energy emergency to enable increased in‑state output and reduce the risk of supply shocks — Insurance Journal.
Regulatory pressure and cost accounting
Chevron singled out California environmental changes — notably adjustments to the Cap-and-Invest program and new California Air Resources Board (CARB) rules — as raising compliance costs and undermining the economics of refining. The company warned CARB amendments would remove millions of carbon allowances from 2027 to 2030 as the state pushes to reach more aggressive reduction targets — Insurance Journal.
In a letter to Gov. Gavin Newsom, Chevron estimated the proposed changes could add about $500 million in costs over five years, raise pump prices by roughly $1 a gallon by 2030, and threaten hundreds of thousands of jobs tied to the energy sector and supply chains. The company framed those risks as threats to both economic reliability and national security — Insurance Journal; Fox Business.
California’s energy isolation
California is not well connected to the main U.S. pipeline networks that link Gulf Coast refiners to inland and West Coast markets. That isolation has made the state an energy island, relying on local refineries for most of its gasoline. Losing a major refinery could sharply tighten statewide capacity and trigger price spikes — analysis cited by Insurance Journal and BIC Magazine.
State and regulator responses
State officials and regulators have pushed back. CARB is holding public hearings and says it will consider stakeholder input before finalizing amendments that aim to meet aggressive climate goals. Gov. Newsom’s office characterized recent warnings from oil companies as part of a “coordinated campaign” to avoid new rules; Chevron and other firms reject that framing. The debate is expected to play out at a public CARB hearing in late May — Insurance Journal.
Market conditions and price signals
Global oil prices have climbed past $100 per barrel amid the Iran war, putting additional pressure on refiners and consumers. U.S. diesel prices have topped $5 per gallon in many areas, underscoring how sensitive transportation fuels are to crude costs and refining capacity. Chevron warns that layered regulatory costs on top of market pressures make California operations increasingly unsustainable — Insurance Journal; Fox Business.
Implications for Paso Robles
Economic impact
Paso Robles, in San Luis Obispo County, depends on steady, reasonably priced fuel for agriculture, trucking, tourism and local businesses. A statewide pump price increase of even $0.50 to $1.00 per gallon would raise operational costs for farmers, vineyard operators and hospitality businesses, squeezing already tight margins — based on Chevron’s estimates and coverage by Insurance Journal and Fox Business.
Fuel availability and daily life
Paso Robles uses the same regional distribution system as much of coastal Central California. If a major refinery outage forces rationing or freight-route disruptions occur, local stations could face shortages or delayed deliveries. Residents who commute or work in agriculture could see pump lines and price shocks similar to past refinery outages — reporting summarized by Insurance Journal.
Local jobs and the economy
While Paso Robles does not host Chevron’s largest refineries, the county economy is linked to California’s energy sector. Logistics, trucking, and small businesses that depend on lower-cost fuel would feel pressure from statewide refining declines. Some regulators project a possible one‑third reduction in capacity if two large refineries closed — a ripple that would affect rural economies — Insurance Journal; BIC Magazine.
Public services, emergency response and national security
Higher fuel costs and shortages can affect emergency services, school transportation, and public works in San Luis Obispo County. Chevron has highlighted military fuel needs as part of the national security concern; local readiness and response plans could be strained if state fuel supplies are disrupted. Local governments are advised to assess contingency plans for prioritized resupply to police, fire, and medical services — Insurance Journal.
Practical steps for Paso Robles leaders
- Monitor regulatory developments: Track CARB amendments and participate in public hearings; CARB is taking stakeholder input before final votes — Insurance Journal.
- Review local fuel emergency plans: Prioritize deliveries to first responders and critical services, and verify alternate suppliers.
- Coordinate regionally: Work with county partners to explore temporary stockpiling or alternate logistics if refinery capacity drops.
- Communicate with the public: Advise residents and businesses on conservation measures to reduce demand during tight periods.
