Providing certainty for the development of low-to-zero carbon alternative jet fuel production in Washington state.

SB 5932 provides certainty for low-to-zero carbon alternative jet fuel (sustainable aviation fuel) production in Washington by clarifying tax incentives and carbon accounting rules. It establishes a 0.275% tax on manufacturing and sales of alternative jet fuel, effective when facilities reach 20 million gallons annual capacity (or July 1, 2031 at the latest), and expires after nine years. The bill requires the Department of Ecology to allow specific carbon intensity calculations for electricity used in production, using the utility’s reported fuel mix rather than separate tracking. This directly affects fuel producers, processors, and utilities supplying energy to these facilities, reducing investment risks by creating a clear timeline for tax benefits.
