Co2news is preparing a Global Decentralized Carbon Credit Market (Global Carbon Ledger – GCL)

We will create transparent, verifiable and secure market, where governments, businesses and individuals can trade carbon credits, biodiversity certificates or other environmental credits.
Blockchain will ensure that each credit is unique, verified and untraceable. sell twice.


Key principles
  1. Global unified database – all credits have a digital identity on the blockchain (NFT or tokenized record).
  2. Measurement and verification – credits are created only after independent verification (MRV system – Measurement, Reporting, Verification).
  3. Transparency – all transactions are publicly traceable, but sensitive project data can remain anonymized.
  4. Interoperability – the platform will be connected to existing systems (Verra, Gold Standard, EU ETS).
  5. Automation – smart contracts control the issuance, trading and "retirement" of credits.

Technological architecture
  • Blockchain layer: Ethereum, Polygon or other low-emission PoS chain.
  • Credit tokenization:
    • Carbon Token (C-TKN): 1 token = 1 t CO₂e removed or offset.
    • Biodiversity Token (B-TKN): for nature conservation certificates.
    • Water Token (W-TKN): for water purification and rainwater harvesting projects.
  • MRV integration:
    • satellite data (e.g. ESA, NASA)
    • IoT sensors (e.g. measuring afforestation, methane emissions)
    • AI data analysis for automatic approval
  • API for exchanges and platforms – an open interface for connection with existing voluntary and regulated markets.

Trading mechanism
  1. Issuance of credit
    Project (e.g. afforestation, carbon sequestration, DAC – direct air capture) sends data → MRV verifies → blockchain issues token.
  2. Trading
    Credits are listed on a global decentralized exchange (DEX) + integrated with major exchanges (CME, EEX).
  3. Withdrawal (cancellation)
    After being used to offset emissions, the credit is burned (burn transaction) to prevent double use.
  4. Verification of ownership
    Anyone can verify on the blockchain who bought or used the credit and when.

Usage examples
  • Multinational corporations – meeting ESG goals and offsets.
  • Governments – linkage with carbon taxes and national climate strategies.
  • Individuals – the ability to purchase microcredits via a mobile application.
  • Banks and investors – carbon credits as an investment asset.

Advantages over the traditional system
  • No duplication of credits.
  • Instant transaction verification anywhere in the world.
  • Lower intermediary costs.
  • Improved investor confidence in green projects.
  • Possibility of microtransactions (e.g. offset for one flight ticket or package of goods).

Platform financial model
  • Transaction fee (0.5 – 1 % of the trade value).
  • Project registration fee.
  • Premium services (analytics, ESG reporting).
  • Token economy option (GCL governance token).
