What Puro.earth does
Puro.earth Oy, headquartered in Helsinki, Finland, is a private B2B carbon removal crediting platform founded in 2018/2019 that operates a registry, standard, and marketplace exclusively for engineered carbon dioxide removal (CDR). It issues and tracks CO2 Removal Certificates (CORCs) under the Puro Standard across eight quantification methodologies including biochar, geologically stored carbon, enhanced rock weathering, carbonated materials, marine anoxic carbon storage, direct air capture with ocean storage, microalgae carbon fixation and sinking, and terrestrial storage of biomass. As of June 2026, the Puro Registry has issued over 1.5 million CORCs representing 1,748,536 tonnes of removed CO2, with 1,019,738 CORCs retired, 826 buyers and beneficiaries, 323 registered CDR suppliers, and 115 certified projects; the platform claims 74% share of the CDR market by removed tonnes.
Puro.earth's business model rests on three revenue streams: (1) certification fees, restructured in October 2024 from a percentage of CORC trading value to a fixed cost per tonne of CO2 removed (payable only when a certificate is purchased), lowering barriers for smaller suppliers; (2) marketplace commissions on CORC trading facilitated through direct channels and partners like Accend; and (3) premium services such as Puro Issuance Plus (subscription-style accelerated issuance). Distribution combines direct enterprise sales, self-service via the MyPuro 2.0 portal, banking channels (Standard Chartered, SEB), and marketplace integrations via Puro Connect APIs (dMRV Connect, Trade Connect, Registry Connect).
The company serves two primary customer segments: CDR suppliers and project developers (biochar producers, DAC operators, ERW projects, geological storage facilities) seeking certification and bankable offtake pathways, and corporate buyers with net-zero commitments (Microsoft, Google, BCG, McKinsey, Booking.com, Swiss Re, Block, Rothschild & Co) seeking high-integrity, permanent removal credits. Nasdaq acquired a majority stake via an €11 million Series B in September 2025, and Puro.earth received ICVCM CCP-Eligible status in December 2025, positioning it as an institutional-grade registry for both voluntary and emerging compliance CDR markets.

Revenue model
- Certification Fees: Puro.earth charges fees for carbon removal certification services. The revised fee structure (effective October 2024) shifted from CORC trading value to a fixed cost calculated from reported tonnes of CO2 removed, with suppliers paying only when a certificate is purchased rather than at issuance. This lowers barriers for smaller CDR suppliers and eliminates upfront costs.
- CORC Trading: Revenue generated from carbon credit transactions on the platform. The platform facilitates trading of CO2 Removal Certificates between suppliers and buyers including corporate entities and financial institutions.
- Premium Services: Puro Issuance Plus premium service enables industrial carbon removal suppliers to issue verified CORCs more frequently, improving liquidity and revenue predictability. This service builds on digital infrastructure upgrades.

Puro.earth competitors and assessment
Company assessmentDirect peers
- Isometric: Isometric operates a CDR-specific registry and verification protocol, directly competing with Puro.earth to certify durable carbon removal credits. It is one of the closest direct competitors in the engineered CDR registry category.
- Carbonfuture: Carbonfuture is a CDR registry specializing in biochar and other durable removal pathways with verification standards similar to Puro's. It directly competes for biochar supplier certifications and buyer contracts in the same category Puro dominates.
Broad incumbents
- Verra: Verra operates the Verified Carbon Standard (VCS), the world's largest voluntary carbon credit program. It is expanding into engineered CDR methodologies, making it a broad incumbent whose scale and existing market relationships could pressure Puro's market share over time.
- Gold Standard: Gold Standard is a major voluntary carbon credit standard with strong relationships among corporate buyers and project developers. As it expands methodology coverage, it represents a broad incumbent competitor to Puro's registry and certification business.
- Climate Action Reserve: Climate Action Reserve (CAR) is a North American carbon offset registry developing protocols for various removal pathways. It is a broad incumbent whose institutional credibility and government relationships overlap with Puro's buyer base.
Emerging players
- Sylvera: Sylvera provides independent ratings and analytics for carbon credits, including CDR. While not a registry itself, it influences buyer perception of credit quality and competes indirectly for the buyer-analytics value chain adjacent to Puro's certification work.
- Renoster: Renoster operates a CDR marketplace and project finance platform. It is an emerging player that overlaps with Puro on the buyer-facing marketplace layer and competes for supplier and buyer mindshare in the early-stage CDR ecosystem.
- Pachama: Pachama is a carbon credit marketplace leveraging satellite and AI verification. While primarily focused on nature-based credits, it competes for corporate buyer attention and procurement workflows that Puro also serves.
- Patch: Patch provides API infrastructure for carbon credit procurement, including CDR credits. It competes indirectly with Puro's Puro Connect APIs by offering a different integration model for buyer-side carbon credit procurement.
- Cloverly: Cloverly operates an API platform for carbon credit purchasing across removal and avoidance categories. It overlaps with Puro on the buyer-procurement layer and competes for enterprise software integrations and corporate sustainability platforms.
