The California Air Sources Board voted to amend the Low Carbon Gas Customary on Nov. 8, updating a sweeping transportation fuels program that incentivizes initiatives nationwide and seeks to decarbonize the sector.
The amendments package deal was backed by clear fuels teams whose membership contains waste corporations like WM and Republic Companies. However public debate was consumed by considerations that the amendments lock in subsidies for combustion fuels and anaerobic digesters on dairy farms at a time when environmentalists are urging a speedy transition to zero-emission autos.
Throughout a marathon listening to, the board additionally greenlit plans to craft a brand new regulation requiring dairy farms to handle their methane emissions. The regulation is ready to enter impact by 2030, six years later than CARB was licensed to start regulating the potent greenhouse gasoline on such farms.
Environmental advocates say the board missed a chance to handle methane emissions at a time when different industries are already grappling with related restrictions.
“The best way to get sure reductions from the industries which might be the biggest emitters is to manage them,” Invoice Magavern, coverage director for the Coalition for Clear Air, mentioned. “You may’t have all carrots and no sticks.”
California’s prime 5 sources of methane emissions
Agricultural operations have been chargeable for roughly half of California’s methane emissions in 2022, as measured in metric tons of carbon dioxide equal.
LCFS evolution
CARB first authorized the LCFS program in 2009 and carried out it in 2011, and has now handed a significant amendments package deal for this system twice. The board says this system has been successful, decreasing the carbon depth of California’s general gasoline combine by almost 13%, together with displacing 70% of petroleum diesel. Biogas trade teams additionally estimate about 97% of the pure gasoline used as car gasoline in California is renewable pure gasoline, thanks partially to this system.
After greater than a yr of debate on this newest modification package deal, an array of trade voices urged the board to approve it, together with the Coalition for Renewable Pure Fuel, Low Carbon Fuels Coalition, utility Southern California Edison and United Steelworkers Native 326, which represents employees at a Phillips 66 plant transformed to provide low-carbon diesel. They argue change is required as this system has suffered from cratering credit score costs over the previous couple of years.
This system requires oil and gasoline corporations that present fossil fuels to Californians to buy credit from producers of other fuels with decrease carbon intensities. These intensities are supposed to be decided by the gasoline’s potential to contribute to international warming.
Just lately, a flood of renewable diesel and robust funding in other forms of lower-carbon depth fuels have overwhelmed the LCFS credit score market, driving credit score costs down and contributing to what trade insiders see as a dampening of funding in cleaner fuels.
The biogas trade’s most well-liked answer to this concern is to speed up the obligations of fossil-based gasoline producers. CARB adopted this philosophy with the brand new amendments. It’s going to now require a 30% discount in carbon depth of the state’s gasoline combine by 2030, quite than the earlier 20% requirement. The newest spherical of amendments additionally would enable CARB employees to equally step-up the requirement a number of years from now if one other credit score oversupply happens.
“This system is doing such an excellent job at decreasing carbon emissions, it is clear that this system can do extra,” Patrick Serfass, government director of the American Biogas Council, mentioned in an interview previous to CARB’s vote. “Why would the state not reply to that and attempt to do greater than what was anticipated when this system was first created over a decade in the past?”
However some environmental teams have argued this system has change into unwieldy because it was first carried out. Over time, CARB has labored to handle an ever-growing vary of gasoline applied sciences utilizing the LCFS program. That features gasoline refined by dairy digesters, which have obtained drastically decrease — and extra profitable — carbon depth values than different biogas amenities, akin to these at landfills or wastewater remedy crops.
Business voices that advocate for the present carbon depth values embedded within the LCFS argue this system evaluates all types of fuels and strategies of making them the identical manner. However environmental teams imagine the other is true, saying policymakers have put their thumb on the size in favor of dairy digesters to please agricultural pursuits and buyers.
Aaron Smith, a professor on the College of California, Berkeley, has studied the affect of the LCFS program’s averted methane credit score for dairy digesters, the mechanism that enables such amenities to obtain low carbon depth values. Smith discovered that dairy digester builders obtain a return on funding after about 10 years of receiving an averted methane credit score. Past that, the credit score probably serves as a windfall for buyers with no coverage goal, he wrote.
These considerations have been echoed in feedback submitted by Jim Duffy, a retired CARB official who beforehand led the LCFS program. “No different trade is handled as if their methane air pollution is of course a part of the baseline after which lavished with massive monetary incentives for merely decreasing their very own air pollution,” Duffy wrote.
He additionally famous that the improved credit for dairy methane weren’t a part of the unique LCFS program adopted in 2009. Relatively, they have been added in a earlier modification cycle about six years in the past.
The biogas trade, for its half, pushes again on Smith’s analysis and argues the credit score is required for motion.
Todd Campbell, vp of public coverage and regulatory affairs for digester developer and pure gasoline fueler Clear Power Fuels, mentioned Smith relied on “wildly optimistic assumptions” over credit score costs in his calculations. He additionally argued that the farms most fitted to digesters more and more have already been constructed out, leaving smaller dairies that may take longer to web builders a return on funding to construct.
“The initiatives are getting harder to construct and function. Not the opposite manner round,” Campbell mentioned in an emailed assertion.
Clear Power Fuels has constructed a number of anaerobic digesters for dairy farms across the nation, together with this one in Iowa. These amenities can nonetheless earn credit score by way of California’s program, although CARB may section out that capacity for sure amenities as quickly as 2037 because of the brand new amendments.

Others have argued that this extra incentive for dairy digesters shifts funding towards dairy farms quite than different equally vital sources of methane.
“Fuel derived from landfill has a way more reasonable carbon depth rating versus dairy gasoline, regardless that it is functionally the identical know-how. You are capturing methane that will have gone into the environment anyway,” Jamie Katz, a employees lawyer for the Management Council for Justice & Accountability, an environmental justice group, mentioned.
“No different trade will get this presumption that their methane goes to be freely vented,” she added.
The biogas trade pushes again on this assertion. They are saying the incentives are essential to spur dairy farms into motion to handle their methane emissions, and additional argue that any minimization of the credit included in this system during the last a number of years may spook buyers.
“What is basically, actually disruptive, particularly to the funding group, is making fast, speedy modifications,” Serfass mentioned. “The success of this program revolves round non-public trade funding, and if you happen to disrupt non-public trade funding an excessive amount of, you type of kill this system.”
The way forward for LCFS
Whereas the amendments have been authorized, the battle over how CARB regulates methane by way of the LCFS and different applications will proceed.
Previous to the 12-2 vote, a number of board members acknowledged however didn’t transfer to undertake lots of the suggestions of CARB’s personal Environmental Justice Advisory Committee, a comparatively new physique that weighed in on the LCFS as certainly one of its first official acts. Katz mentioned that was regarding, significantly for the lower-income communities that stay close to industrial dairy farms in California’s San Joaquin Valley.
Katz mentioned that by locking within the averted methane credit score for many years, CARB can also be locking in a particular type of managing manure methane that residents residing close to these amenities have complained about for years. CARB’s assurances that initiatives constructed over the following a number of years will proceed to obtain beneficiant credit may focus extra digesters in those self same communities, Katz argued.
To Sasan Saadat, a former analysis and coverage analyst with Earthjustice, the board may have taken a a lot less complicated method. Relatively than dashing up the carbon depth scale for the LCFS to spur greater credit score costs, the board may have merely rolled again a few of the additional crediting it gives to dairy farms and sure different biofuels. Doing so would have an effect on the provision of credit quite than the demand, he argued.
“By relying solely on juicing up demand by way of elevated stringency, CARB is considerably operating the chance of accelerating this system’s general prices,” to drivers of gasoline or diesel-powered autos, Saadat mentioned. “I’d characterize it as a wealth switch from California drivers to the buyers that put money into these digesters.”
Regardless of a last-minute try from a board member to restrict credit for dairy digesters, CARB in the end selected to lock in as much as 30 years of incentives for digesters already constructed and as much as 20 years for digesters constructed by 2030. These incentives will probably be out there to amenities regardless of the board’s simultaneous plan to start requiring dairy farms to start controlling their methane by way of an as-yet-unwritten regulation.
CARB has theoretically been licensed to create a regulation mandating methane emission reductions from livestock manure administration operations, together with from dairies, because the passage of SB 1383 in 2016. That regulation may have gone into impact on Jan. 1, 2024, however till not too long ago the board has been reluctant to pursue a rule. Now, board members indicated such a regulation would probably be carried out by 2030.
Environmental teams are already making ready to foyer for a robust methane regulation, taking one other stab at defending weak communities amid an power transition.
“They don’t seem to be eliminating us any time quickly,” Katz mentioned. “We will hold exhibiting up.”
For now, the biofuels funding group views the board’s vote as a inexperienced mild to trade to ramp up improvement. California already hosts a 3rd of all dairy digesters within the nation, and extra in California and elsewhere may quickly break floor because of continued incentives, in accordance with the American Biogas Council.
Within the amendments package deal, the board additionally voted to permit a “deliverability” requirement for biogas that will require initiatives credited by this system to inject their renewable pure gasoline right into a grid that straight connects to the California. Regardless of urging from some environmental justice advocates that such a provision be carried out sooner, CARB may elect to implement that requirement in 2037 on the earliest.
