WA SB5856

Exempts emissions from the combustion, oxidation, or other end use of lubricants from Washington's cap and invest program, using the federal definition of "lubricant" found in 40 C.F.R. Sec. 98.6 (2025)

Exemption applies automatically regardless of whether a fuel supplier demonstrates to the Department of Ecology that a lubricant is not combusted or oxidized

Amends RCW 70A.65.080, which defines covered entities and emissions thresholds under the state's cap and invest carbon market program

Adds lubricant emissions to the existing list of exempt emissions, which includes aviation fuels, certain watercraft fuels, biomass/biofuels, agricultural fuels, and national security facilities
