CA SB285

Establishes that only "qualified carbon dioxide removal" (CDR) may be used to counterbalance remaining greenhouse gas emissions when meeting California's net zero emissions goals, including the 2045 net zero target

Defines qualified CDR requirements: must use agricultural residues, forestry residues, or municipal organic waste if biomass is needed; cannot be used for enhanced oil recovery; and must meet specified environmental standards

Requires emissions from fossil fuels or long-term mineral sources to be offset only with "durable carbon dioxide removal" that uses long-term storage with financial responsibility requirements equivalent to geological sequestration standards

Mandates separate reporting of greenhouse gas emissions and CDR used to counterbalance those emissions, with sufficient detail to demonstrate compliance with durability matching requirements

Authorizes the State Air Resources Board indefinitely (removing the January 1, 2024 deadline) to adopt protocols supporting methods for utilization or storage of captured or removed carbon dioxide
