Chevron warns California could face fuel shortage as war, taxes squeeze refineries
Chevron President Andy Walz warns California could face severe fuel shortages and record gas prices as the Iran war disrupts shipments and proposed cap-and-invest taxes threaten refinery operations — possibly forcing Chevron to exit the state within ten years.
- Chevron warns it may leave California within 10 years if state policies remain unchanged — a move that could remove roughly 34% of the state’s refining capacity. Insurance Journal
- Global supply shocks from the Iran war and disrupted Strait of Hormuz shipments have tightened Asian supplies that normally help California. Insurance Journal
- Regulatory costs — notably proposed cap-and-invest amendments and a refinery tax — could add roughly $500 million in Chevron costs over five years and more than $1 per gallon by 2030, industry warns. Fox Business
- Local vulnerability: California refines >90% of its gasoline locally and imports ~70% of its crude, leaving the state exposed to local outages and international disruptions. Insurance Journal
The perfect storm: war and regulation
Chevron frames the risk as two forces converging: a global supply shock tied to the Iran war and costly state policies. Walz said shipments through the Strait of Hormuz have been affected and many Asian refiners are cutting output, forcing more expensive routing alternatives. Insurance Journal
Regulatory pressure and the cap-and-invest debate
Chevron singled out changes to California’s Cap-and-Invest program and a proposed tax on refineries as contributors to rising operating costs. Walz warned state leaders directly:
“They need to abandon the tax on refineries or they won’t have any refineries in 10 years. If it stays that way — Chevron will be gone in 10 years for sure. We won’t be able to make it.”
The company estimates the California Air Resources Board’s stricter emissions rules could cost Chevron roughly $500 million over five years, and warns those costs would translate into higher pump prices by 2030. Fox Business
California’s dangerous energy isolation
California is effectively an energy island. The state’s refining and delivery network is largely disconnected from continental U.S. pipelines, meaning more than 90% of gasoline used there is refined locally. A shutdown of major refineries would create immediate local shortages and sharp price spikes. Insurance Journal
Chevron operates two of California’s largest refineries; the California Energy Commission estimates that losing Chevron’s operations would cut state refining capacity by roughly 34% — a reduction that could strain supplies of gasoline, diesel and jet fuel.
Reliance on foreign crude and Asian supplies
About 70% of California’s crude comes from foreign sources, with a significant share from Asia. When Asian suppliers tighten or ban exports amid global shipping instability, California’s pool of imports shrinks. Chevron described relying on Asian imports during such instability as “a dangerous game.” Insurance Journal
Price impacts and economic risks
California already pays some of the nation’s highest pump prices — averages near $6 per gallon versus a national ~$4 per gallon. Chevron warns the proposed cap-and-invest amendments could add more than $1 per gallon by 2030, and that tighter caps risk hundreds of thousands of industry jobs through higher compliance costs. Fox Business
The Air Resources Board proposal would remove 118.3 million allowances from the market between 2027 and 2030, tightening permit supply and raising costs for refiners and other large emitters.
National security concerns
Walz framed refinery closures as a national security risk: California is a major consumer of jet fuel and hosts more than 30 military bases. “Refinery closures in California reduce fuel supply resilience on the West Coast, increasing risks to military readiness and national security,” he said.

Industry response and operational workarounds
To cope with supply shocks Chevron has shifted some shipments from the Gulf Coast to California via the Panama Canal. These measures help shore up supplies but are costly and limited. The company warns such fixes are temporary if international disruptions continue and state rules raise long-term costs. Insurance Journal
Legal and policy context
In a letter to Gov. Gavin Newsom, Chevron criticized evolving regulations and said “adversarial policies at local, regional and state levels have eroded” the economic and national security benefits of California’s energy industry. The company urged reconsideration of refinery taxes and the cap-and-invest amendments now debated at the California Air Resources Board. Insurance Journal
Implications for Walla Walla, Washington
Economic and price impact: Walla Walla families and businesses could face higher fuel costs as California price spikes often influence national averages. Higher gasoline and diesel prices raise household travel costs and increase operating expenses for farms, trucking and local businesses.
Supply chain risks for agriculture: Local growers rely on diesel for tractors, harvesters and transport; sustained West Coast shortages could squeeze margins and raise consumer prices.
Energy market ripple effects: While Washington has a distinct network, West Coast disruptions reduce regional flexibility and can shift demand pressure to other coastal suppliers.
Political and policy echoes: Local leaders and voters may press elected officials to weigh energy reliability and jobs when considering climate policy trade-offs.
National security and readiness: Walla Walla supports National Guard units; reduced refining capacity complicates logistics and training readiness.
Practical steps for the region: Review fuel contracts, increase on-site reserves if feasible, coordinate with distributors, and engage state representatives. Chambers of commerce and farm bureaus may consider joint outreach to highlight local impacts.
