Washington is joining California and Québec in a multi-jurisdictional carbon emissions trading market, aiming to reduce greenhouse gases more efficiently. The draft agreement focuses on information sharing, accounting, and cooperation, with the goal of driving long-term, cost-effective investment in decarbonization. The Climate Commitment Act, established in 2021, sets a target to reduce Washington's greenhouse gas emissions by 95% by 2050. Public input and assessments are required before formal entry into the linkage agreement, with the potential for a linked carbon emissions trading market by 2027. The partnership aims to create a larger, more stable market for emissions allowances, bringing substantial benefits to the state's cap-and-invest program, economy, and communities as it works to decarbonize and meet emissions reduction goals.
