Today California regulators will consider toughening carbon-slashing targets and raising hurdles for crop-based fuels to participate in North America's largest Low Carbon Fuel Standard (LCFS).
California's Air Resources Board will weigh rulemaking underway for nearly a year — and on the verge of running out of time — to restore shrinking incentives in the state's program to decarbonize road fuels. The decision comes amid growing outcry over the cost of diversifying the state's fuel portfolio passed on to drivers. Choices made on incentives in the largest US renewable fuels and electric vehicle charging markets may offer some clarity to markets now roiled by uncertainty over the approach an incoming second Donald Trump administration will take.
LCFS programs require yearly reductions to transportation fuel carbon intensity. Higher-carbon fuels that exceed the annual limit incur deficits that suppliers must offset with approved, lower-carbon alternatives.
California's program has helped spur a rush of new renewable diesel production that quickly overwhelmed the deficits generated from petroleum gasoline and diesel use in the state. LCFS credits do not expire, and leftover credits available for future compliance grew to 29.1mn metric tonnes by July. The program generated 22.4mn deficits in all of 2023.
Tougher targets on tap
Board approval of amendments considered today would immediately toughen program targets for 2025 by 9pc. The one-year drop would nearly double reductions first proposed last year, and require cuts six times deeper than the typical year-to-year change in targets. Regulatory staff published models in April suggesting such a target could thin a smothering inventory of excess credits available for future compliance by 8.2mn — roughly a third of the available excess credits.
Other proposals would take longer to begin. California would require new attestations about land use for crop-based feedstocks by 2026, shifting toward tougher verification requirements for such feedstocks by 2031. Regulators would limit credit generation for existing suppliers of biodiesel and renewable diesel made from soybean oil or canola oil credits to only 20pc of such fuels they supply to California by 2028. And CARB would begin phasing out outsized credit generation from renewable natural gas used in transportation in 2040, after locking-in incentives for current projects regardless of any regulations that would mandate methane reductions.
The program has faced a late push of opposition from fuel suppliers and environmental critics highlighting costs to previously unaware drivers. The campaign inspired an unusual volume of public comment filings in October from residents focused on gasoline costs. But CARB faces a 5 January deadline to approve the proposals. Missing it would restart the regulatory process, which staff has said could take another two years to complete. Credits available for future compliance nearly tripled over the past two years. Renewable natural gas, electric vehicle and even biofuels groups wary of elements of the proposal have issued statements of support this week.
Chairwoman Liane Randolph has repeatedly defended the program in public appearances as the temperature on fuel costs concerns rose. Targets must get tougher, she said earlier this year. She reiterated the need for the standard in response to media questions about the lack of information about potential cost increases.
CARB's choices will ripple across fuel supply strategies around the world. California used two thirds of the renewable diesel consumed in the US during the second quarter, and access to the market can determine feedstock margins. With immediate federal choices on biofuel tax incentives or possible feedstock sanctions uncertain, clarity on California's may offer suppliers one of the fuel planning footholds this year.
