California Carbon Linkage Report Targets Pre-Election Window as CARB Capacity Runs Thin
With Washington's program proposal submitted and a gubernatorial race approaching, CARB faces competing regulatory deadlines that could shape California's allowance market before a new governor takes office.
Canary Media reported on September 16 (2026-09-16) that Governor Gavin Newsom's final year has been dominated by electricity cost pressures, with critics questioning his legacy on ratepayer bills during heat waves — a political backdrop that now surrounds the California Air Resources Board's push to publish a linkage study before voters choose his successor.6
California's cap-and-invest program sits mid-revision while CARB simultaneously races to complete that study. Washington regulators submitted their proposal to enable a 2026 linkage agreement with California on June 1 (2026-06-01), according to Carbon Pulse reporting. Two jurisdictions are now moving toward a shared allowance pool at the same moment the California program's structural parameters remain unsettled.2
CARB's workload is visible in the slippage elsewhere. On June 30 (2026-06-30), the agency granted companies covered by Senate Bill 253 an additional three months to disclose scope 1 and scope 2 greenhouse gas emissions, according to a CARB bulletin. That delay signals bandwidth constraints: the same agency processing a cap-and-invest revision and a linkage study is also managing a major corporate disclosure law.4
The market being discussed is not peripheral. Cap-and-Invest has generated $36.2 billion for climate investments since its inception in 2013, according to a CARB report released July 30 (2026-07-30). The program covers roughly 80% of the state's emissions, applies to facilities emitting 25,000 metric tons or more of CO2 equivalent annually, and is designed to run through 2045. The same report credited the program with emission reductions worth 130.5 million metric tons of CO2 equivalent to date, and cited $44.4 billion in cost savings from lower fuel consumption, transit expenses and household energy bills.5
The revision approved earlier this year carries the sharpest supply implication. In January, CARB determined it had to remove allowances equivalent to 188 million metric tons of emissions from circulation to meet its 2030 decarbonization target, with a 40% reduction in emissions below 1990 levels as the benchmark. Newsom praised the vote in a Friday (2026-05-29) statement. Critics of the revised plan argued it weakens the program's environmental integrity, Canary Media reported.1
Linkage changes the arithmetic on that withdrawal. A merged California-Washington allowance pool would widen the buyer base and introduce cross-border fungibility. How Washington's cap compares to California's, and how the two programs handle the 188 million metric ton reduction, will determine the effective supply constraint in any linked market. The pre-election report is the first official read on whether the two programs can be reconciled without softening California's cap.2,1
Separately, first-of-their-kind carbon capture and storage rules drew industry support and environmental opposition when they were released, E&E News reported on June 12 (2026-06-12). That regulatory fight is downstream of cap-and-invest but competes for the same agency attention, and it has its own timeline independent of the election.3
The political risk runs in both directions. Newsom has managed PG&E's 2019 bankruptcy, rolling blackouts in 2020 and 2022, and what Canary Media described as the current threat of refinancing pressure — a record that shapes how much political capital remains for tightening the carbon market in his final months. A successor could slow or accelerate the linkage track, and the incoming governor would inherit an unfinished file if the report slips past the vote.6
The practical signal to track is whether the linkage report publishes before polling day. If it does not, the allowance market will be pricing a program whose next policy direction was set by an administration that is gone — and whose successor has not yet committed to the same timetable.2,1
