There’s a new player in carbon removal. It’s not another startup building machines to suck carbon from the air. And it’s not another trade association or consulting firm or marketplace peddling carbon removal credits. Instead, it wants to help establish a different system for advancing carbon removal — one where the challenging but important goal of scrubbing CO2 from the atmosphere is treated as a public good and not just a business opportunity.
It’s called the Carbon Removal Standards Initiative, and it’s run by Anu Khan, the former deputy director of science and innovation at Carbon180. CRSI (pronounced like the Lannister queen in Game of Thrones, “Cersei”) is a “financially unconflicted, independent nonprofit,” that will provide technical assistance to policymakers, regulators, and nongovernmental organizations in quantifying carbon removal outcomes.
A group providing technical assistance may not sound like a revolutionary development. But Khan hopes CRSI will be a fulcrum around which the entire industry can begin to pivot.
Today’s carbon removal industry is built on selling credits, each of which is supposed to represent one ton of CO2 pulled out of the atmosphere. But the market is almost entirely self-regulated. The standards for measuring and reporting how much carbon a given project is removing have either been developed by the carbon credit registries that take a cut of the sales or by the developers themselves — in both cases a conflict of interest, even if governed by the best of intentions. Plus, there’s a multitude of standards for every type of project, and they vary in quality.
Take carbon farming, for example. If a farmer alters their practices to increase the carbon stored in their soil, they can choose from more than a dozen standards to quantify the effects. In theory, the standards all produce an identical product — a fungible carbon credit equivalent to one ton of carbon removed from the atmosphere. In reality, they vary widely in quality, with some standards producing more accurate results than others.
In watching this environment develop over the past several years, I’ve often wondered if some independent, unbiased entity might eventually step forward to enact one set of standards to rule them all. Khan told me that about a year and a half ago, she had the same thought. “Oh, to be so young,” she said.
At the time, there was growing concern that the carbon removal industry would suffer from the same credibility issues that plagued the wider market for carbon credits. “You have a multiplicity of these verification entities driven by profit motives, some of which have very loose standards,” Wil Burns, the co-executive director of the Institute for Carbon Removal Law and Policy at American University, told me. “From the standpoint of those purchasing credits or those viewing whether companies are doing anything meaningful, nobody can really distinguish.”
In early 2023, dozens of carbon removal suppliers, buyers, verifiers, academics, and nonprofit staff — including Khan — signed an open letter that now reads like an early draft of CRSI’s missions statement. It called for the creation of “an independent, not-for-profit initiative that conscientiously avoids conflicts of interest and has funding that does not depend on issuing or selling carbon credits.” This new body would “provide a trusted, scientific stamp of approval for CDR protocols through an inclusive process to identify scientific consensus.”
The letter focused on the issues with measuring carbon removal in the context of the voluntary sale of carbon credits. But over the next year, it became clear to Khan that carbon removal won’t reach the scale necessary to make a dent in climate change without government policy. “Even the market enthusiasts recognize that we’re going to need policy as quickly as possible to shore this up,” she said, “and it’s going to be policy, long term, that gets us to gigaton scale.”
So instead of providing “a trusted, scientific stamp of approval” to private businesses, CRSI is laser focused on working with policymakers. It’s not entirely clear yet what that will look like, and it’s likely to evolve as CRSI finds its footing. But the group is launching with a few projects that are already underway. It has created a database of “quantification resources,” which is basically a list of all of the methodologies published by companies, academics, government agencies, and international standards organizations, for measuring different kinds of carbon removal. It also has a database of carbon removal policies, both those enacted and proposed. Eventually, Khan plans to have them link out to each other, so you can see which standards underpin which policies.
Khan wants CRSI to be a go-to resource for policymakers and agency staff to ensure that carbon removal programs actually result in climate benefits. “We are fundamentally a mission organization,” she told me. “We believe that carbon removal is a tool for climate justice. Justice requires accountability, and in carbon removal, that means knowing how to count the carbon. We want to make sure that if we're putting public dollars into these policies, that they are backed by the ability to actually measure the carbon.”
Khan isn’t the only one whose thinking on standards has shifted toward a government-led approach. Burns, who also signed the letter, told me he’s seeing more carbon removal companies pushing for a compliance market, where the government requires polluting businesses to buy carbon removal. “They would like to both have government standards that would provide more confidence, for example, to investors,” he said, “and they would like government mandates that generate more demand.”
Freya Chay is the program lead at the nonprofit Carbon Plan, which spearheaded the letter. She told me many in the industry are now thinking about carbon removal programs that don’t revolve around selling credits at all, and therefore may have very different measurement and verification needs.
One of CRSI’s first projects is an illustrative example. Imagine if the Department of Agriculture developed a program to help farmers restore the pH of soils that have gotten too acidic, by adding basalt — a mineral that also happens to capture CO2 from the atmosphere as it dissolves. Today, carbon removal companies that sell carbon credits based on this process are taking hundreds of soil samples to measure the outcomes. The USDA likely wouldn’t need that level of precision — the captured CO2 is a co-benefit, not the entire point of the program — but “at some point you probably do want to know if you removed carbon through this policy,” said Khan. CRSI is working on figuring out how you would do that.
Similarly, we might see the development of building codes that encourage the use of concrete cured with CO2 from the atmosphere, or waste management regulations that govern the injection of carbon-rich organic waste into underground storage wells. Bigger picture, the U.S. will eventually have to measure and report how much carbon removal it’s doing across all of these little programs as part of its obligation under the Paris Agreement.
In many of these cases, those setting the rules won’t be experts in carbon removal science. “They’re going to need technical expertise,” said Khan. “We want to make sure that when they are doing that work, they have access to all of the relevant information, and that it’s organized in a way that’s legible for the expertise that they already have.”
Shuchi Talati, the former chief of staff in the office of fossil energy and carbon management at the Department of Energy, told me that having this kind of centralized resource would definitely have been useful. “The private sector has a lot of power right now in setting standards because the public sector doesn’t have the capacity,” she said. And since the field is so diverse, efforts are spread across a bunch of different agencies that don’t always talk to each other. Talati sits on the board of CRSI, and for her, the focus on government is not just about helping carbon removal scale.
“If we’re allowing the private sector to set standards and norms — and maybe they’re fine right now — but if we continue to let that happen, I can see the actual climate benefit of CDR slipping away,” Talati said. “That’s really where I see Anu’s organization fit in, where we are trying to set standards and norms from this core, foundational principle of a public good.”
