Marathon Petroleum Corporation sent an urgent letter to California Gov. Gavin Newsom, warning him of the consequences of backing theCap-and-Invest program, adding it was “deeply concerned.”

“California refineries are already among themost expensive refineries to operate in the world,” the letter reads, next referring to the California Air Resources Board, or CARB.

“CARB’s proposal would further widen the cost disparity, forcing refineries to reconsider whether operations in California remain viable.”

It comes asgas prices spiked againovernight by nine cents, meaning on average it costs $5.29 per gallon to fill a car.

CARB’s 2026 proposals aim to tighten the state’s climate policies and boost corporate transparency.

Key measures include amendments to the Cap-and-Invest Program toaccelerate greenhouse gas reductionsand new rules requiring large companies to report emissions and climate-related financial risks.

Updates to the Low Carbon Fuel Standard would expand access to cleaner fuels and zero-emission infrastructure.

The package also addresses refinery emissions and allows first-year flexibility for reporting, all as part of California’s broader push for carbon neutrality by 2045.

According to the California Energy Commission, the Cap-and-Invest program currently adds about 24 cents per gallon to the cost of gasoline in the Golden State.

“This action will undermine the security of California’s fuel supply, directly affect consumers, and create significant economic, workforce, and national-security consequences,” Marathon’s Michael Henschen wrote in his letter.
