Americans choking at the pump in Phoenix and Fargo should be thanking California, not blaming it. The state’s diesel hit $8.35 a gallon this week, a $1.95 premium over the national average of $6.40.
That premium tells a story the petro-state apologists would rather you did not hear.
Nationwide diesel has surged as the war in Iran disrupts supply, Ukrainian drone strikes on Russian energy infrastructure have pushed the Kremlin to ban diesel exports to manage domestic shortages and support its military, and the result is a global diesel shortage that lands hardest wherever the market is unprepared.
California spent years getting prepared.
Gasoline in the state carries a $1.65-a-gallon premium over the national average. Diesel carries a $1.95 premium. Read those numbers again. In the middle of a war-driven global diesel crunch, the state that bet hardest on alternatives still has fuel moving.
That is not a bug.
That is the point.
California’s Low Carbon Fuel Standard was designed to scale up diesel made from non-petroleum sources, including vegetable oils and animal fats. It did. The regulation forces refiners and importers to cut the carbon intensity of their fuel, typically by blending in renewable content or buying credits from renewable producers.
The LCFS adds about 29 cents to a gallon of diesel. That 29 cents bought the country something extraordinary: an actual domestic alternative supply.
Two refinery complexes in the San Francisco Bay Area that once processed about 280,000 barrels a day of crude have been converted into renewable-fuel plants with a combined capacity of about 100,000 barrels a day.
The doomsayers call that a refining loss.
It is a refinery renaissance.
The same facilities. The same workers. The same port infrastructure. Repurposed at scale into the energy economy the rest of the country is still arguing about in court.
California lost crude-refining capacity. It gained energy independence. The math has flipped in the state’s favor, and the current war has confirmed the bet.
Every barrel of renewable diesel produced in those Bay Area plants is a barrel that does not have to be loaded onto a tanker in the Persian Gulf. California has spent years substituting domestic agricultural and waste-based feedstocks for imported crude.
That is what industrial policy looks like when it works.
California also layers a 13% sales tax, plus local sales taxes, on diesel. It adds a 48.2-cent-a-gallon state excise tax on top of the 24.4-cent federal excise tax. The layers look punitive in any cross-state comparison.
They are the price of a carbon-intensive fuel economy that the rest of America has been freeloading on.
California is internalizing the cost. The other forty-nine states have been externalizing it onto the atmosphere and onto their grandchildren.
The current price spike makes the policy choice obvious. With the war in Iran rattling Middle Eastern supply chains and Ukrainian drone strikes on Russian energy infrastructure prompting the Kremlin to ban diesel exports outright to mitigate domestic fuel shortages and support its military, diesel is becoming a geopolitical chokepoint.
California is partially buffered from that volatility because the LCFS built an actual domestic alternative supply while other states’ refiners kept optimizing for one more quarter of margin on crude.
The $1.95 premium is not a punishment of truckers. It is the price America pays for a state that took climate policy seriously while the rest of the country was still drafting memos about whether the problem existed.
Railroads and truckers moving cargo out of West Coast ports absorb real costs, and some of those costs pass to consumers in Phoenix and Fargo.
That is the bill for refusing to participate in the next petro-shock.
It is also the price of carbon-priced fuel in a country that has refused to price carbon. Every other state’s cheap diesel is subsidized by climate consequences no one has yet billed them for.
Americans looking for someone to blame should look at the war in Iran, the Kremlin’s diesel export ban, and the petrostate leverage that leaves every country without a renewable-fuel standard vulnerable to the next shutdown.
They should not blame Sacramento.
They should look at Sacramento and ask why every other governor in the country has not copied the playbook.
Gov. Gavin Newsom’s reported maneuvering toward a 2028 presidential bid deserves more than cheap jokes about his travel carbon footprint. A governor who built the Low Carbon Fuel Standard, helped convert two refineries from foreign crude to domestic renewables, and internalized a climate cost the rest of the country has hidden is offering precisely the leadership the federal government has lacked for a quarter-century.
Someone should be tracking his CO2 emissions.
But so far, his footprint is a fraction of what the war machine just burned through.
California’s $8.35 diesel is not a scandal.
It is a preview.
