Tax accounts for 15% of the pump price here — 78.6¢ a gallon, state and federal combined. Even that understates it: Climate Commitment Act cap-and-invest allowance costs, which are embedded in the wholesale price sit outside these figures and land in the “everything else” row, so treat that row as an upper bound on margin rather than a measure of it. See our methodology for how each row is derived.
Washington now carries the second-highest fuel tax burden in the country, and the cost of its cap-and-invest carbon programme sits on top of that.
Five refineries at Cherry Point, Anacortes, Ferndale and Tacoma supply the state, running Alaska North Slope and Canadian crude. Together they refine about 90% of the petroleum products consumed in Washington and Oregon. Like the rest of the West Coast, Washington has no pipeline connection to the Gulf Coast.
Puget Sound refining serves Washington, much of Oregon and part of the inland Northwest. The concentration means regional maintenance schedules matter a great deal.
Washington does not require a California-style reformulated blend statewide, but its participation in West Coast product markets ties it to the region’s specification-limited supply pool.
