CnerG

What CnerG does

CnerG is a South Korea-headquartered digital procurement platform for Renewable Energy Certificates (RECs) and voluntary carbon credits, founded in 2020. The platform connects corporate buyers of renewable energy and carbon offsets with project developers across more than 108 countries, with a registered base of 352+ organizations spanning major multinational energy, automotive, commodities, and financial services firms. Core products include a marketplace for bilateral REC and carbon credit transactions, an Entity Dashboard that centralizes account-level procurement and compliance tracking, a Demand & Recommendations engine that matches buyers to suitable projects, and an indicative REC pricing reference product that surfaces market benchmarks. CnerG maintains a direct sourcing model with renewable energy developers and operates regional trading hubs in Singapore, the Netherlands, and the United States.

The business model is a transaction-based marketplace: CnerG intermediates the procurement of RECs and carbon credits, earning fees on the volume it facilitates between buyers and project developers. Enterprise buyers access the platform for renewable energy procurement tied to Scope 2 reporting and for voluntary carbon offsets tied to Scope 3 and corporate climate commitments. The platform integrates with the I-REC registry through a partnership with Evident, providing issuance infrastructure for compliant certificate transactions. CnerG has been B Corp Certified since 2025, a credential it leverages for enterprise procurement processes that require verified impact claims.

The company has scaled rapidly: export revenue grew from KRW 1.56 billion in 2023 to KRW 16.5 billion in 2024, with H1 2025 export revenue of KRW 13.07 billion indicating sustained momentum. Growth has been funded through multiple rounds culminating in a KRW 46 billion Series A, with capital deployed into the Monsoon Carbon acquisition (expanding into Southeast Asia and MEA), product development, and the establishment of regional trading hubs. The team remains relatively small at 11-50 employees, consistent with a digital marketplace scaling primarily through technology rather than headcount.

Direct peers

• Patch: API-first carbon credit marketplace that enables software platforms and enterprises to embed carbon credit purchasing directly into their products. Directly competes with CnerG's marketplace and developer-facing workflow, particularly for digital-first buyers seeking transparent pricing per tonne.
• Cloverly: Carbon credits API and marketplace providing vetted offsets, RECs, and aviation SAF for enterprises. Operates a similar model to CnerG's Marketplace plus SaaS tooling, with a focus on API integration for sustainability platforms and corporate procurement teams.
• South Pole Group: Global climate consultancy and carbon credit developer active across voluntary and compliance markets with a strong advisory plus trading offering. Comparable to CnerG as both a credit originator and procurement enabler for corporate decarbonization and RE100 strategies.
• 3Degrees: Environmental commodities and renewable energy services firm offering RECs, PPAs, and carbon offsets to enterprises; also listed as a CnerG customer/partner. Closely comparable in offering and target buyer to CnerG's marketplace and trading business.
• Watershed: Enterprise carbon accounting and reduction platform covering Scope 1–3 measurement, reporting, and procurement of credits and RECs. Competes directly with CnerG's Carbon Accounting and Supply Chain Management modules for the same sustainability budget owner.
• Persefoni: Climate management and accounting platform serving enterprises with carbon footprinting, decarbonization planning, and audit-grade reporting. Overlaps with CnerG's SaaS modules (Carbon Accounting, Corporate Entity Management) for compliance-driven buyers.

Emerging players

• Pachama: Marketplace and AI-driven verification platform focused on nature-based carbon credits (REDD+, afforestation, removals). Comparable as a digital-first carbon credits marketplace, though narrower in scope than CnerG's broader REC and trading portfolio.
• Klima: Digital carbon credits marketplace and consumer-facing offset app, focused on transparent pricing and SME access. Overlaps with CnerG's marketplace on price transparency and buyer self-service flows, with greater focus on small-volume buyers.

Broad incumbents

• ENGIE Global Markets: Energy major with a dedicated environmental commodities trading desk selling RECs, GOs, and carbon credits to global enterprises; also a CnerG customer/partner. A broader incumbent that competes on supply origination rather than platform tooling.

Others

• Puro.earth: Carbon removal registry and standard for engineered carbon removal (BECCS, biochar, DAC); a CnerG-listed standards partner. Adjacent rather than directly competitive — operates upstream as a registry/issuer that feeds marketplaces like CnerG.
