California's cap-and-trade and Low Carbon Fuel Standard added about 47 cents per gallon of gasoline in July 2026, according to the California Energy Commission. Washington's carbon auction adds roughly 31 to 50 cents per gallon depending on allowance prices, with clean fuel rules adding more. Oregon's programs add about 10 cents per gallon today and could reach 22 cents by 2030. New York's economy-wide cap-and-invest has not started, so its costs are not showing up at the pump yet.

Useful breakdown. The California numbers are the only ones with a real state agency line item, so the 47 cent figure is solid. The Washington range is wide because the auction price moved. Good that they kept taxes separate.
The RFS section is the messiest. Gross credit math says 32 to 37 cents but net pass-through has averaged around a cent for years. That gap matters for anyone trying to estimate actual pump impact.
The electricity side is thin. LBNL says 5% average RPS compliance cost, but EPIC says 11 to 17% after 7 to 12 years. Those are measuring different things, and the article should say which one applies to a given state's bill.
New York being listed as a climate cost state but not having a running program is a useful check. Too many roundups count planned policies as if they already affect prices.
The distinction between carbon auction pass-through and clean fuel standard costs is important. They are different mechanisms with different compliance markets. Blending them into one climate tax number makes the policy debate worse.
For households, the gas number gets the attention, but the electricity side matters more over time. RPS costs at 5 to 10 percent of the bill are modest compared to what electrification will need in grid investment.
