As required by the Climate Commitment Act (CCA), Ecology is investigating the option of linking Washington’s Cap-and-Invest carbon market with the California-Québec carbon market. Through linkage, Washington’s carbon market would combine with the joint California-Québec market to create a single shared market with joint allowance auctions and a common allowance price across all jurisdictions. Allowances could be traded across jurisdictions and used to cover emissions in any of the three jurisdictions. The law also requires Ecology to evaluate specific criteria to ensure linkage would benefit Washington’s communities, economy, and climate goals. Ecology is pursuing linkage with California and Québec based on a preliminary analysis that joining a larger carbon market will lead to lower and more consistent allowance prices, benefitting businesses and consumers in Washington. This Environmental Justice Assessment is separate from the Environmental Justice Assessment being conducted on the Cap-and-Invest Linkage Rulemaking. Additionally, Ecology previously conducted an Environmental Justice Assessment on the 2024 carbon market linkage agency request legislation (Senate Bill 6058). We will consider input received through those other linkage related Environmental Justice Assessments in this Assessment. While the completion of each of these Environmental Justice Assessments is a separate legal obligation, Ecology intends to approach them as a comprehensive, iterative process of engagement and consultation that will continually inform our awareness and understanding of potential impacts as well as potential methods to minimize or eliminate harms and maximize benefits for vulnerable populations and overburdened communities. All of these processes must be complete before Ecology can sign a linkage agreement.
