One of California’s marquee applications for cleansing up transportation emissions is at a crossroads. Decisions made within the subsequent few months may set the decade-and-a-half-old Low Carbon Fuel Standard on certainly one of two very totally different paths.
One path, favored by fossil gas and renewable pure gasoline pursuits, would lock in a market scheme that presently extracts billions of {dollars} per 12 months from Californians on the pump and subsidizes crop-based and cow-manure-derived biofuels.
That could be a catastrophe, in response to environmental advocates, who level to a rising physique of scientific proof exhibiting that this strategy, if prolonged till 2045 as proposed, would trigger these biofuels to develop at a scale that may hurt the local weather and the surroundings.
The different path, proposed by environmental teams, transportation-decarbonization analysts and local weather and vitality researchers, would restrict the scope of unsustainable biofuels in this system, and as a substitute reorient it to assist what consultants agree needs to be California’s main clear transportation pathway: electrical automobiles.
To date, roughly 80 % of LCFS funding has gone to combustion biofuels fairly than electrical automobiles. That’s merely incompatible with the state’s EV ambitions and desires, mentioned Adrian Martinez, deputy managing lawyer of nonprofit advocacy group Earthjustice — and the crucial to cut back emissions from transportation, which account for practically 40 % of the state’s greenhouse gasoline emissions.
“We’ve obtained to eradicate our reliance on combustion,” he mentioned, however “this system as designed will proceed to supply profitable incentives for flamable fuels effectively into the long run.”
The regulator in command of the LCFS program — and this high-stakes choice — is the California Air Resources Board. CARB’s board, which contains 14 voting members, 12 appointed by the governor and two by the state legislature, holds a host of obligations round California’s vitality transition. Those embrace shaping the state’s nation-leading EV coverage, in addition to figuring out its broad plans for attaining long-term greenhouse-gas discount objectives.
Critics say the LCFS program’s rising assist for biofuels is in direct distinction to each the EV targets and the local weather objectives additionally overseen by CARB — and that this system has been captured by deep-pocketed industries attempting to greenwash the continued use of combustion fuels.
CARB has a likelihood to reform this system with an upcoming vote, initially set for this month, however now postponed to an undetermined future date. But its pathway to fixing the issues that plague LCFS is murky and messy at greatest.
Right now, the employees managing the LCFS program hasn’t given CARB board members a chance to select a climate- and EV-friendly various. Instead, a December employees proposal offers just one possibility for the board to vote on later this 12 months: a set of insurance policies that Earthjustice forecasts would direct $27 billion over the approaching decade towards biofuels and worsen results on the local weather, the surroundings and the costs that Californians pay on the pump.
CARB does have another choice, nevertheless — another proposal laid out by CARB’s Environmental Justice Advisory Committee, created to advise the board on environmental-justice points.
That proposal would cap the fast-growing share of crop-based renewable diesel flooding the state. It would additionally finish the weird construction that now permits biogas produced by dairy farm manure to offset a a lot larger quantity of carbon emissions than another supply of other fuels.
And, importantly, it might make the core of this system — its carbon-offset market — perform in a a lot more healthy manner, proponents say. A torrent of low-cost, polluting renewable diesel and dairy farm biogas credit have dragged down the value that LCFS credit can fetch for avoiding emissions, diluting the motivation to deploy new local weather applied sciences and sapping what might be a key funding supply for EV infrastructure within the state.
“The stakes are very, very excessive,” Martinez mentioned. “That’s why you see a lot consideration centered on this — and a very broad and various coalition that’s pushing for extra systemic change to this system, versus extra modest tweaks that can actually simply maintain this market owned and dominated by fossil gas pursuits.”
A historical past of the LCFS program
California’s Low Carbon Fuel Standard was born out of AB 32, the 2006 legislation that created the state’s carbon cap-and-trade market. Much like carbon markets, LCFS is supposed to make corporations pay for his or her carbon emissions by shopping for credit from applied sciences that cut back carbon emissions.
The program requires all fossil fuels refined and offered in California to fulfill more and more stringent carbon-intensity targets. In apply, fossil gas producers have to purchase a bunch of LCFS credit from low-carbon transit sources working within the state so as to comply. The purpose is to create a system that taxes planet-warming fossil fuels to fund cleaner transportation alternate options.
But the LCFS has strayed from its preliminary give attention to car electrification and “superior” non-crop-based biofuels to develop into “a swag bag for enterprise capitalists, large oil, large agriculture, and large gasoline, more and more coming on the expense of low- and moderate-income Californians.” That’s how Jim Duffy, a 13-year veteran of the company who served as department chief of the LCFS program from 2019 to 2020 and retired in 2022, described the evolution of this system in feedback filed with CARB.
Under the LCFS regulation adopted in 2009, dairy-manure-to-biogas initiatives didn’t obtain particular remedy in comparison with different sources of methane akin to landfills and sewage remedy vegetation, Duffy wrote. Similarly, diesel fuels constructed from crops like soybeans have been thought of “solely marginally higher than fossil diesel.”
But within the years since, “the LCFS was revised to supply extra and pointless assist to landfills and first-generation crop-based biofuels” and “to mitigate the methane drawback created by the dairy trade itself,” Duffy wrote — even supposing proof more and more means that each sources hurt the planet excess of they profit it.
The outcome has been an rising share of LCFS credit being equipped by renewable diesel and dairy-generated biogas.
CARB has justified these shifts with evaluation indicating they’ll yield internet optimistic local weather impacts.
“The proposed amendments now into account will immediately improve this system advantages in essentially the most burdened communities, by decreasing the carbon throughout the availability chain for fuels offered in California, in addition to bettering public well being for fuels offered in California,” CARB spokesperson Dave Clegern mentioned in an e-mail to Canary Media. He cited knowledge from CARB employees’s evaluation of its proposal indicating that, by 2045, its plan will cut back nitrogen oxide emissions by 25,586 tons, lower greenhouse gasoline emissions by 560 million metric tons and yield public-health value financial savings of practically $5 billion.
But critics say the company is failing to account for the complete scope of local weather harms that might be brought on by its continued emphasis on biofuels.
They warn that the sheer scale of California’s program — totaling some $4 billion per 12 months — is driving funding within the incorrect transportation alternate options. The penalties are dire, they are saying — not simply throughout the state, however throughout the nation and across the world.
Why renewable diesel is threatening CARB’s local weather and credit score objectives
Take renewable diesel, a gas constructed from fat and oils processed to be similar to fossil diesel gas. The U.S. elevated manufacturing of the gas by 400% between 2019 and 2022, and it’s set to double it once more this 12 months, in response to Jeremy Martin, senior scientist and director of fuels coverage for the Union of Concerned Scientists.
Unlike ethanol and biodiesel, which may solely partially change gasoline and diesel, renewable diesel has “no restrict on how a lot might be blended,” Martin mentioned. It may theoretically utterly change diesel gas for vans, buses and different automobiles. And California’s LCFS gives credit on prime of the federal incentives the gas receives, making the state the first goal of renewable diesel producers throughout the nation.
As a outcome, the share of renewable diesel as a proportion of whole diesel gas use has skyrocketed in California in comparison with the remainder of the U.S., because the chart under reveals.
In a September assembly, Steven Cliff, CARB’s government officer, highlighted a milestone for the LCFS program: As of mid-2023, California had “greater than half of our diesel demand being met by non-petroleum-based diesel alternate options. This is a direct results of the LCFS program, and it’s bringing actual local weather and air-quality advantages to the state.”
In Martin’s view, that milestone isn’t a win, however a warning. It signifies that renewable diesel is “flooding the LCFS, drowning the coverage — and it doesn’t make sense” on local weather or environmental phrases.
Once the demand for renewable diesel outgrows the availability of waste oils and different non-crop feedstocks that can be utilized to make the gas in genuinely climate-friendly methods, it turns into extremely probably that it’ll trigger extra greenhouse gasoline emissions than it can displace. Critics like Martin argue that demand has now reached this level, although it’s a contested query.
This extra demand for crop oils may largely serve “to increase the cultivation of palm oil to interchange the soybean and different oils made into gas,” the Union of Concerned Scientists argued in feedback to CARB. That, in flip, is more likely to result in extra speedy deforestation in nations that produce massive quantities of those crops, akin to Brazil and Indonesia — an consequence that may trigger far better local weather harms than no matter emissions reductions outcome from changing fossil diesel.
To cease this, the Union of Concerned Scientists and different teams need CARB to set a restrict on how a lot renewable diesel can obtain LCFS credit. CARB employees’s proposal declines to set such a cap, citing renewable diesel’s local weather and well being advantages.
But CARB’s methodology is out of step with the most recent science, in response to a number of teams learning these points. The Union of Concerned Scientists, for its half, says CARB’s evaluation is “primarily based on inaccurate claims of local weather and air-quality advantages and related well being outcomes.”
In a latest comparability of 5 totally different fashions for evaluating the local weather impacts of crop-based biofuels, the U.S. Environmental Protection Agency discovered that solely CARB’s personal mannequin reveals a optimistic carbon-reduction influence.
And whereas the company has a proposal to restrict deforestation harms by setting “sustainability pointers” for crops getting used for renewable diesel, it applies solely to feedstocks grown within the U.S., Martin famous. That’s a drawback: California is on tempo to devour 10 % of world soybean oil provides for renewable diesel, which means a vital quantity of the crop oil produced for this system might be grown beneath circumstances CARB can’t police, he mentioned.
Given that actuality, Martin mentioned, “If California declines to behave — if they are saying, ‘This is proof of success; look how little fossil diesel we’re utilizing’” by changing it with renewable diesel, “then, in truth, California is giving its assist to a gas that we all know is unsustainable at these volumes.”
