- California regulators have eased rules for its carbon market, potentially releasing up to $4 billion in free emissions allowances to industrial companies. This move aims to mitigate rising energy costs and inflation concerns, particularly for gasoline prices. However, environmental groups and some economists argue this could weaken emissions reduction incentives and reduce funding for state programs, potentially impacting California's climate targets. The direct impact on broader US equity markets is neutral as it's a localized regulatory adjustment.

Investing.com -- California regulators approved changes to the state’s carbon market that could provide up to $4 billion in additional free emissions allowances to oil refiners and other industrial companies, Bloomberg reported on Friday.
The California Air Resources Board (CARB) voted to revise its Cap-and-Invest program, granting additional free allowances to help companies comply with greenhouse gas emissions limits while limiting potential increases in fuel and consumer costs.
The move comes as policymakers face growing pressure over inflation and elevated gasoline prices, which climbed sharply during the conflict in the Middle East.
Under the revised plan, regulators will offset the removal of 118 million emissions allowances from the market by creating an equal number of free allowances through 2035. The allowances would be available to oil refiners and other industrial companies for decarbonization projects.
The amended rule also includes roughly $800 million in support aimed at preventing additional costs from being passed on to consumers at the gas pump.
The changes sparked opposition from environmental groups, local officials, and some economists, who warned the additional allowances could weaken incentives to reduce emissions and lower carbon prices.
According to the report, some critics argued the revisions could make it more difficult for California to achieve its target of carbon neutrality by 2045 and reduce funding for programs supported by carbon market revenues.
A report from California’s Legislative Analyst’s Office said the changes could reduce certainty that the state will meet its 2030 emissions targets. The office also estimated annual auction revenues could fall to about $2 billion from roughly $4 billion previously.
Those revenues help fund a range of state initiatives, including affordable housing, public transit, wildfire resilience projects and California’s high-speed rail program.
CARB officials defended the changes, arguing they improve affordability without undermining the effectiveness of the state’s climate policies.
The board also directed staff to conduct additional analysis before issuing the new allowances after some members raised questions about the potential impact on emissions and market pricing.
California’s carbon market, which covers industries responsible for roughly 80% of the state’s greenhouse gas emissions, has been widely viewed as one of the most influential emissions trading systems in the United States.
