UN Climate Report Exposes the Contradictions in California’s Oil Policies

The United Nations’ latest climate assessment delivers a sobering message: rapid growth in renewable energy has not eliminated the world’s dependence on fossil fuels. For California, the findings raise a fundamental question about the state’s energy policies: what is accomplished by restricting local oil production while continuing to consume petroleum imported aboard oceangoing tankers?

As highlighted in POLITICO’s Surge newsletter, the UN Environment Programme’s 2026 Emissions Gap Report finds that global temperatures are set to exceed 1.5 degrees Celsius above preindustrial levels. Even full implementation of countries’ climate commitments would leave the world on a trajectory toward approximately 2.6 degrees of warming this century. The report still identifies a potential pathway back to 1.5 degrees by 2100, but doing so would require steep emissions reductions and increasing deployment of carbon removal.

POLITICO describes the practical obstacles behind that gap. Energy systems cannot be replaced simply by adopting ambitious targets. Power plants, vehicles, industrial facilities, and buildings remain in service for decades. Expanding renewable generation also requires transmission, storage, and other infrastructure, while growing electricity demand adds another challenge. Affordability, reliability, and energy security remain essential considerations throughout that transition.

For CIPA, those realities underscore the contradiction in California’s campaign against its own oil producers. Restricting local supply does not automatically eliminate the demand that supply serves. When Californians continue using petroleum, diminishing the state’s ability to produce it creates opportunities for replacement supplies from elsewhere.

The state’s own figures illustrate the extent of that dependence. According to the California Energy Commission, foreign crude supplied 61.1 percent of California refinery receipts in 2025, compared with 25.7 percent in 2000. Over the same period, the California supply category fell from 49.5 percent to 22.9 percent. These figures document a substantial shift toward foreign dependence, although multiple factors have contributed to the change.

The climate irony is difficult to miss: California discourages production close to its refineries while relying on oil transported across oceans. Supertankers burn fuel and generate emissions when moving that crude to California. Where suitable local crude can replace an imported barrel through existing pipeline connections, that ocean voyage can be avoided.

The precise climate benefit requires comparing the entire supply chain, including production methods, methane emissions, transportation, and refining. California crude and foreign crude each vary in their emissions intensity. Nevertheless, policymakers should examine the emissions added by long-distance shipping before treating the disappearance of a California-produced barrel as an environmental victory. Moving production beyond the state’s borders does not make its climate consequences disappear.

CIPA’s position is that California should partner with its producers to meet continuing petroleum demand responsibly, reduce operational emissions, and preserve reliable supplies to local refineries. Maintaining that production and refining infrastructure can also support California jobs and reduce exposure to overseas disruptions.

The UN report calls for reductions in global emissions. California should apply that global perspective to its own supply decisions. A policy that substitutes imported oil and additional tanker voyages for suitable local supplies deserves scrutiny, especially when the state could instead work with producers to deliver crude directly to nearby refineries. Climate leadership should be measured by the emissions actually avoided across the supply chain.
