Chevron warns of California fuel shortage warning, says taxes and regulations could drive company from state in 10 years
San Ramon, California (High Desert News Online) – Chevron President Andy Walz warned California could face fuel shortages, soaring pump prices and the loss of major refiners within a decade unless state leaders revise refinery taxes and regulations that threaten in‑state production.
Key takeaways
- Chevron’s president Andy Walz says the company could leave California’s refining business within 10 years unless refinery taxes and regulatory rules change.
- Walz warned Iran-related disruptions to shipping through the Strait of Hormuz are straining supply lines and raising the risk of local fuel shortages.
- Chevron says proposed Cap-and-Invest changes could add about $500 million in industry costs over five years and push pump prices up to $1 per gallon by 2030.
- A Chevron shutdown would reduce California’s refining capacity by roughly 34%, endangering supply for a state that relies heavily on in‑state refineries.
Walz’s warning: supply shocks and regulation
Andy Walz told state officials that two forces are squeezing California’s fuel system: a supply shock caused by Middle East tensions and a regulatory and tax climate that, he says, makes refining here unsustainable. He said Chevron is moving some Gulf Coast supply through the Panama Canal because of disruptions around the Strait of Hormuz. Insurance Journal
Walz argued that tighter emissions caps planned under the California Air Resources Board and proposed changes to the Cap-and-Invest program could pull 118.3 million allowances from the market for 2027–2030 and add roughly $500 million in costs to the industry over five years, which he said will raise gasoline costs and weaken reliability.

If it stays that way Chevron will be gone in 10 years for sure. We won’t be able to make it,
Walz said, warning state leaders they risk losing refineries, jobs and regional security. Insurance Journal
Why California is vulnerable
California is often described as an “energy island.” Its pipeline links to other U.S. refining hubs are limited, and the state depends on local refineries for most of its gasoline and jet fuel. The California Energy Commission reports that more than 90% of gasoline used in the state is refined in‑state, making local outages particularly damaging. Insurance Journal
Chevron operates two of the state’s largest refineries. A loss of those operations, Chevron says, would remove roughly one‑third of the state’s capacity — a concentration that amplifies the impact of any closure or slowdown. Insurance Journal
The state also imports refined fuels and crude from Asia and elsewhere. Walz pointed to cuts in Asian refinery runs — partly tied to Iran-related transport issues — that have reduced product exports. He called relying on imports from distant markets a “dangerous game” for California supply security. Insurance Journal
Economic and security stakes cited by Chevron
Chevron linked the proposed changes to a range of risks, saying the Cap-and-Invest tweaks and other measures could:
- Increase retail fuel prices by as much as $1 per gallon by 2030. Insurance Journal
- Put hundreds of thousands of jobs at risk; Chevron referenced analyses citing more than 536,000 jobs potentially affected. Insurance Journal
- Undermine national security because California hosts more than 30 military bases that rely on steady fuel supplies. Insurance Journal
Walz urged Gov. Gavin Newsom to declare an “energy emergency,” trim refinery taxes, and promote in‑state production to shore up domestic supply. He also criticized what he described as “offshoring” of carbon emissions — reducing in‑state consumption without ensuring production and jobs remain local. Insurance Journal
Regulatory context: Cap-and-Invest and state response
The Cap-and-Invest program is California’s carbon market: it caps emissions and requires companies to hold permits for the carbon they produce. Chevron’s letter objects to proposed amendments that would tighten the cap and withdraw allowances from future years, increasing compliance costs. Insurance Journal
State officials pushed back. A Newsom administration spokesman accused oil companies of using the Iran war to run a “coordinated campaign” to shift blame for higher prices and protect profits. The California Air Resources Board said it plans public hearings on the Cap-and-Invest changes in late May and will consider input from industry and the public as it finalizes rules.

Broader market forces: oil prices and production trends
Global oil prices have risen amid Middle East tensions. U.S. diesel topped $5 a gallon in some markets, and crude briefly passed $100 a barrel as supply fears grew. Those shifts add to the squeeze on refineries facing higher input costs and disrupted shipping lanes. Insurance Journal
At the same time, California’s onshore oil production has declined over decades. That long-term fall in local crude output, paired with limited pipeline links, leaves the state more exposed when international shipping routes are threatened or when local refineries face regulatory pressure. Insurance Journal
Federal moves and industry reaction
In response to concerns about domestic supply, federal actions have aimed to boost California production. The Trump administration authorized Sable Offshore Corp. to restart certain California offshore oil production using wartime powers to expand domestic output. Insurance Journal
Industry leaders say federal and state policies should align to ensure reliable supplies. Critics of Chevron’s position counter that the company stands to profit from higher prices and that tighter caps are necessary to meet climate goals. The debate centers on balancing short-term supply security with long-term emissions reductions. Fox Business
Implications for The High Desert, California
Economic impact
The High Desert region depends on fuel for commuters, trucking, and local industry. A cut in statewide refining capacity or a spike in gas prices would raise costs for residents and businesses in Victor Valley, Lancaster, and Palmdale, affecting household budgets and delivery costs. Insurance Journal
Political consequences
Local officials could face pressure to push state leaders for carve-outs or relief on refinery taxes. Lawmakers aligned with moderate conservative voters may use Chevron’s warning to argue for rolling back taxes or slowing Cap-and-Invest changes, while climate-focused leaders will stress maintaining emissions reductions. Insurance Journal
Social effects
Commuters who travel long distances and rural, lower-income households would be hit hardest by higher fuel costs. Emergency services, school transportation and local buses could see operating cost increases, creating pressure on county budgets. Insurance Journal
Cultural relevance
The High Desert’s mix of conservative-leaning communities and residents who value local jobs means arguments that environmental rules threaten employment may resonate — even as many residents support cleaner air and climate goals, producing local tension over policy choices. Insurance Journal
Practical applications: how local leaders can prepare
Local leaders can take practical steps to mitigate short-term disruptions and protect critical services:
- Monitor fuel inventories and coordinate with county offices to identify critical fuel needs for hospitals, schools and first responders. Insurance Journal
- Review emergency plans that assume short-term supply interruptions and build temporary fuel reserves for municipal fleets. Insurance Journal
- Press state officials for targeted relief or phased regulatory changes that avoid sudden refinery closures while preserving emission goals. Insurance Journal
