What UNDO does
UNDO is a London-headquartered carbon dioxide removal (CDR) company that generates permanent carbon removal credits through enhanced rock weathering (ERW). Founded in 2022 and operating as UNDO Carbon Ltd., the company accelerates natural rock weathering by spreading crushed silicate rock — primarily basalt and wollastonite — on agricultural land, where the minerals react with CO2 and water to form stable bicarbonate ions locked into ocean systems for 100,000+ years. UNDO also pursues proprietary measurement, reporting, and verification (MRV) capabilities, most notably the patent-pending SAT-C (SATuration-Centrifugation) porewater extraction method, which has been peer-reviewed and published in Cambridge Prisms: Carbon Technologies, and a world-class geochemical weathering model that predicts CO2 removal rates from rock type, climate, and soil inputs. The company is finalizing the industry's first ERW methodology conformant with ISO 14064 and contributing to the ICROA-endorsed Puro Standard.
UNDO operates a dual-sided business model. On the demand side, it sells carbon removal credits to enterprise customers through a direct field-sales motion; named buyers include Microsoft (three agreements totaling nearly 49,000 tonnes), Barclays (6,538 tonnes), British Airways (~4,000 tonnes), McLaren Racing, Stripe, and Auto Trader. Pricing is negotiated bilaterally and not publicly disclosed. On the supply side, UNDO runs farmer-acquisition programs that supply and spread silicate rock at subsidized or no cost (farmers typically cover only trucking), with 416 farms enrolled and 57,910 acres enriched. The company has spread 335,360 tonnes of rock to date and projects 73,779 tonnes of CO2 removal from current operations. A secondary revenue mechanism is project finance: a pioneering debt facility with Standard Chartered, CFC, CUR8, WTW, and British Airways established a novel non-recourse debt model for ERW projects.
UNDO has raised approximately $12 million in seed equity (May 2023, led by Lowercarbon Capital) and received a strategic investment from Farm Credit Canada. The company operates across the UK, Canada (with engineering/R&D at Kingston via RXN HUB), the US, Australia, East Africa, and — most recently — Brazil, where an exclusive carbon credit partnership with Verde AgriTech expands Latin American reach. It placed third runner-up in the $100M XPRIZE Carbon Removal competition (awarded $5 million) and was nominated for Prince William's Earthshot Prize. Leadership is founder-led by CEO Jim Mann, with CTO Mat Meredith, Head of Carbon Bea Mocci (MSc Carbon Management, Edinburgh), Senior Researcher Dr Amanda Stubbs (geochemistry), plus recent additions including CCO Ryan King and Head of Science & Research XinRan Liu.

Revenue model
- Carbon Removal Credits: UNDO generates revenue by selling carbon removal credits to businesses seeking to offset their emissions. The credits are generated through enhanced rock weathering projects where silicate rock is spread on farmland. The company follows ICROA-certified Puro.earth methodology and ICVCM Core Carbon Principles. Revenue comes from agreements with enterprise customers like Microsoft (nearly 49,000 tonnes total across three deals), Barclays (6,538 tonnes), and others.
- Debt Financing: UNDO receives debt financing from financial institutions like Standard Chartered, CFC, and others as part of novel financing models designed to reduce barriers to carbon removal project finance. This provides upfront capital to scale operations.

UNDO competitors and assessment
Company assessmentDirect peers
- 44.01: 44.01 is an Oman-based enhanced rock weathering company that mineralizes CO2 using peridotite. It is UNDO's closest direct competitor, using the same fundamental ERW chemistry on agricultural land and selling carbon removal credits to enterprise buyers.
- Lithos Carbon: Lithos Carbon is a US-focused enhanced rock weathering developer that spreads basalt on North American farmland to generate carbon removal credits. It directly competes with UNDO on geography (US/Canada), feedstock (basalt), and buyer segment (voluntary corporate purchasers).
- Terradot: Terradot is an enhanced rock weathering company that emphasizes agricultural co-benefits and tropical deployment. It directly competes with UNDO in the ERW category with similar farmer-program mechanics and enterprise credit sales.
- Eion: Eion (formerly Columbia Initiative for Enhanced Rock Weathering) is an early-stage ERW company spun out of Columbia University research that spreads olivine on agricultural soils. It competes directly with UNDO in the same methodology space and targets similar voluntary corporate credit buyers.
- Arca: Arca (formerly Carbfix) is an Iceland-based mineralization carbon removal company that dissolves CO2 into silicate rock formations, achieving permanent storage. It is a direct methodological peer to UNDO's ERW approach, though deploying subsurface mineralization rather than surface agricultural spreading.
Broad incumbents
- Heirloom Carbon: Heirloom is a leading US direct air capture (DAC) company using limestone-based technology to permanently capture atmospheric CO2. It competes with UNDO for the same corporate voluntary carbon removal budgets and has secured large Microsoft and Stripe pre-purchase agreements, but uses a fundamentally different capture pathway.
- Climeworks: Climeworks is the largest-scale direct air capture company globally, with operational DAC plants including Mammoth in Iceland. It is a broad incumbent in the durable carbon removal space that competes with UNDO for high-permanence corporate offtake but operates in the DAC rather than ERW category.
- Charm Industrial: Charm Industrial converts biomass to bio-oil and sequesters it underground as a durable carbon removal pathway. It is a leading frontier CDR company that, like UNDO, has secured large Microsoft pre-purchase agreements and competes for the same corporate voluntary buyer pool at the gigatonne aspiration level.
- CarbonCapture Inc. CarbonCapture Inc. develops direct air capture systems and recently announced a major DAC facility partnership. It competes with UNDO in the broader durable carbon removal category for enterprise pre-purchase contracts, but uses DAC rather than enhanced rock weathering.
Others
- Puro.earth: Puro.earth is the world's leading carbon removals registry and methodology holder with which UNDO collaborates on the ICROA-endorsed Puro Standard for ERW. It is an ecosystem enabler and standards-setter rather than a direct competitor, but sits in the same value chain as the credits UNDO sells.
