California Approves Major Overhaul of Cap-and-Invest Program

The California Air Resources Board (CARB) has approved a sweeping update to the state’s cap-and-invest program, a move that tightens long-term emissions limits while introducing a new pool of free pollution permits for industry [1]. The decision, reached in a 10-3 vote, aims to balance the state’s ambitious climate goals with concerns over rising energy costs and the potential departure of major refineries [1].

Key takeaways

• The plan removes 118 million pollution permits by 2030 to accelerate emissions reductions [1].
• A new "Manufacturing Decarbonization Incentive" creates 118 million additional allowances outside the cap for companies investing in clean energy [1].
• Critics, including environmental and transit groups, warn the changes could slash auction revenue by approximately $2 billion annually [1].
• The update provides more free allowances to industrial facilities and refineries, a move regulators say is intended to stabilize gasoline prices [1].

Balancing Climate Targets and Industrial Stability

The cap-and-invest program, which has operated since 2013, serves as California’s primary mechanism for limiting greenhouse gas emissions by forcing major polluters to purchase permits at auction or receive them for free [1]. Under the new blueprint, the state will reduce the total cap on emissions by 11% annually through 2030, and by 7% annually from 2031 to 2045 [1]. However, the introduction of the Manufacturing Decarbonization Incentive has sparked intense debate. While the program is designed to prevent refineries from leaving the state—following the closure of the Phillips 66 Los Angeles refinery in 2025—opponents argue that the new allowances effectively undermine the program's core function [1].

Caroline Jones of the Environmental Defense Fund noted that the 118 million allowances created for the incentive pool match the exact number being removed from the cap, which critics argue keeps the state from reaching its 2030 climate targets [1]. Furthermore, the Legislative Analyst’s Office projects that this incentive pool will result in a $2 billion annual loss to the Greenhouse Gas Reduction Fund [1]. This fund has historically provided $35 billion for public transit, affordable housing, wildfire prevention, and clean water projects since the program's inception [1].

Why it matters

The overhaul reflects a high-stakes political crossroads for Governor Gavin Newsom’s administration, which is attempting to maintain the state’s climate leadership while addressing economic pressures such as high gasoline prices [1]. Supporters of the update, including utility companies like PG&E, argue the plan strikes a necessary balance between environmental stringency and economic affordability [1]. Conversely, environmental justice and housing advocates warn that the resulting revenue shortfall could lead to significant cuts for essential public programs [1]. As the state moves forward, CARB has committed to holding additional workshops and evaluations before issuing any allowances under the new incentive program [1].
