Cnerg

CnerG is a Korea-headquartered sustainability company that operates a global digital marketplace for environmental commodities, principally renewable energy attribute certificates (EACs/RECs) and carbon credits. The platform allows corporate buyers to explore country-specific products and live prices, check RE100 compliance, submit bulk multi-country buy requests covering different products, volumes, vintages and locations in a single order, negotiate and counter offers within the platform, coordinate work through a shared team workspace with defined roles and access controls, and manage and download redemption certificates at settlement.

On the renewable energy side, CnerG offers unbundled energy attribute certificates including I-REC, US-REC, K-REC, GEC, LGC, T-REC, GO, TIGR and NFC, and supports other procurement routes such as PPAs and VPPAs through its team. On the carbon side, it supports credits across nature-based solutions, carbon removal, methane reduction, waste management, clean cooking, renewable energy and energy efficiency project types, issued under standards including Verra, Gold Standard, Puro.earth and ACR. Beyond procurement, the company provides supply chain (Scope 3) emissions tracking, corporate entity management for compliance, Scope 1 and 2 carbon accounting, and a live REC and carbon credit price index.

The company positions itself as a liquidity provider between corporate demand and a global supply network, and provides end-to-end support including market navigation, regulatory guidance, order registration, settlement, ownership transfer and redemption. It is a Certified B Corporation and publishes an annual market report.

Founding story

CnerG was founded in 2020 with the aim of making sustainability and global decarbonization more connected and accessible for companies of all sizes. Its name is pronounced "synergy," reflecting a stated emphasis on collaboration across teams, regions and stakeholders.

Business model

CnerG operates a cross-border digital marketplace for environmental commodities, connecting corporate buyers with project developers, suppliers and market participants, and also selling directly to buyers to guarantee supply. The marketplace itself is free to use, including account creation, price visibility and request submission, with KYC required for certain sections and transaction steps; sellers do not list or transact directly on the platform, and supply is arranged by CnerG's Global Markets team. Alongside the marketplace, the company offers a suite of SaaS tools for emissions management covering supply chain (Scope 3), corporate entity management and Scope 1 and 2 carbon accounting.
