What Carbony does
Carbony GmbH is an Austrian climate-tech company founded in 2023 and headquartered in Steyr that develops Enhanced Rock Weathering (ERW) carbon removal projects across European non-farmland sites. Its core technology involves spreading finely ground silicate rock dust — specifically high-potential dunite — onto soil where it reacts with atmospheric CO2 and rainwater over years to decades, converting the carbon into long-lived carbonate minerals that migrate downstream for long-term storage. The company distinguishes itself from agricultural-ERW competitors by deliberately avoiding farmland (no competition with food systems) and by applying rigorous site-matched deployment methodology that screens plots for geology, soils, hydrology, and logistics before setting conservative, site-specific dosing.
The company monetizes CO2 removal through the sale of certified European ERW carbon credits to corporate buyers pursuing NET ZERO targets — specifically those whose unavoidable Scope 1 and 2 emissions cannot be eliminated through abatement alone. Revenue also flows from managed project partnerships with corporate funders and landowners, where customers receive capacity allocation, deployment plans, progress updates, certified credit issuance, and communication support for stakeholder reporting. Pricing is not publicly disclosed; all engagements are custom, quote-based, multi-year contracts scoped individually. Go-to-market relies on direct enterprise outreach and a Calendly-based "digital coffee" conversion funnel with the CEO, supported by LinkedIn and Instagram presence and educational website content.
The founding team of five is led by four executives — CEO Matthias Rettenbacher, COO Sandra Gottschall, CTO Silyan Ivanov, and CRO Thomas Rinder. Carbony has assembled an institutional partner ecosystem spanning Austrian and European research and funding bodies: BOKU (University of Natural Resources and Life Sciences, Vienna), Biobase, FFG (Austrian Research Promotion Agency), SCCH (Software Competence Center Hagenberg), KLIEN (Klima- und Energiefonds), EWA, and NEP. The company currently operates only in Europe (Austria-led) and reports no disclosed revenue, customer logos, or dilutive funding rounds in the available source material.

Revenue model
- Certified European ERW carbon credits: Companies purchase certified European ERW carbon credits as part of their NET ZERO strategy. Carbon credits are issued upon verified CO2 removal. Each credit represents a certified, permanent carbon removal outcome with full monitoring documentation.
- Project partnership and allocation: Project partners and funders receive option & allocation (locking capacity and provisional timeline), deployment plans (what happens where and when), progress updates for internal reporting, issuance of certified credits, and communication support for stakeholder reporting without greenwash.

Carbony product offering
Product offeringCore offering
Carbony develops Enhanced Rock Weathering (ERW) carbon removal projects on European non-farmland by spreading finely ground, high-potential dunite rock dust onto soil so that CO2 reacts with the silicate and rainwater to form long-lived carbonate minerals for permanent CO2 sequestration. Its deliverable to customers is certified ERW carbon removal credits and NET ZERO services enabling companies to neutralize unavoidable Scope 1 and 2 emissions with measurement, certification, deployment planning, and stakeholder reporting support.
Product overview
Carbony is a carbon removal company offering Enhanced Rock Weathering (ERW) projects as its core product. The company develops ERW projects using high-potential dunite rock dust applied to European non-farmland, converting atmospheric CO2 into long-lived carbonate minerals. Their offerings include NET ZERO Services (providing certified carbon removal credits for companies addressing Scope 1 and 2 emissions) and Carbon Removals (certified European ERW credits with measurement and certification). They pioneer on non-farmland sites and focus on soil health, plant resilience, and ecosystem services alongside carbon removal.

Products and services
- Enhanced Rock Weathering (ERW) Carbon Removal Projects Engineered Enhanced Rock Weathering (ERW) projects on European non-farmland that spread finely ground high-potential dunite (silicate) rock dust onto soil so CO2 reacts with the rock and rainwater, turning into long-lived carbonate minerals for permanent CO2 sequestration. Site selection is matched to soils, geology, hydrology, rock type, grain size, logistics, and application method, with conservative dosing. Includes soil-health and ecosystem-health monitoring (pH stabilization, Mg/Ca return, plant resilience).
- NET ZERO Services End-to-end corporate NET ZERO service for companies with NET ZERO targets: scope engagement of unavoidable Scope 1 and 2 emissions, deployment planning, progress updates for internal reporting, certified credit issuance, and communication support for stakeholder reporting without greenwash. Delivered as a custom-scoped, multi-year engagement.
- Certified European ERW Carbon Removal Credits Certified, European-sourced ERW carbon removal credits each representing one ton of certified, permanent CO2 removal with full monitoring documentation. Sold to corporate buyers to neutralize unavoidable Scope 1 and 2 emissions; backed by defensible, conservative measurement and reporting (MRV) of every ton removed and separate reporting on soil/yield effects on farmland.
- ERW Project Partnership Program (for landowners and municipalities) Program for non-farmland landowners and municipalities to host ERW rock-dust application projects. Includes site screening (geology, soils, hydrology), option & allocation (capacity and provisional timeline), deployment planning, monitoring, and stakeholder reporting support, delivered as a managed-services engagement.
Quantifiable outcome
- CO2 permanently converted to long-lived carbonate minerals stored downstream — removal is permanent, not temporary.

Carbony competitors and assessment
Company assessmentDirect peers
- Terradot: US-based Enhanced Rock Weathering developer deploying silicate rock for permanent CO2 removal. Terradot is the most directly comparable peer as both companies develop ERW projects, sell certified removal credits, and pursue similar land-based deployment models with rigorous MRV, though at much larger scale.
- Lithos Carbon: ERW developer that spreads basalt rock dust on agricultural lands to sequester CO2. Highly comparable in core technology (silicate rock weathering) and MRV focus, though Lithos targets US farmland whereas Carbony focuses on European non-farmland.
- Eion Carbon: Olivine-based Enhanced Rock Weathering company with a focus on rigorous MRV and credit issuance. Direct peer in the silicate-weathering carbon credit market with a similar enterprise sales motion targeting corporate buyers.
- InPlanet: Tropical ERW developer operating in Brazil with a focus on regenerative agriculture-adjacent weathering projects. Direct peer on core technology though operating in a different (tropical) geography and on farmland rather than non-farmland.
- UNDO Carbon: UK-based Enhanced Rock Weathering startup selling permanent carbon removal credits to corporate buyers. Closely comparable in European geography, enterprise GTM, and certified-credit delivery model.
Emerging players
- Fortera: Developer of carbon-cured cement that mineralizes CO2 into building materials. Compares as an adjacent mineralization-based CO2 utilization pathway with similar underlying chemistry to Carbony's rock-weathering mineralization, though its application is concrete rather than soil.
- KlimateRock: Earlier-stage European ERW developer pursuing similar silicate-rock deployment and corporate-credit distribution. Comparable as a regional early-stage peer competing for European enterprise offtake and grants.
Others
- Puro.earth: Leading registry/methodology provider for geological and biomass carbon removals including enhanced weathering. An ecosystem participant whose certification standards materially affect Carbony's credit pricing, interoperability, and buyer acceptance rather than a direct competitor.
Broad incumbents
- Carbonfuture: German carbon removal project marketplace and registry/methodology developer for nature- and tech-based removals including ERW. Comparable as a European infrastructure layer through which Carbony-issued credits could be sold and verified, rather than as a deployment peer.
- Heirloom Carbon: US-based DAC plus mineralization company that captures CO2 and stores it as carbonate minerals. Broad incumbent in carbon removal that overlaps with Carbony on the mineralization mechanism, but operates a tech-based DAC pathway rather than enhanced weathering.
