Climate change and digital innovation are shaping the future of global finance and humanity. Achieving sustainability and net zero goals, especially for companies seeking to offset emissions and remove greenhouse gases (GHG), poses significant challenges. Carbon trading and carbon markets offer a critical tool in this regard.

There are two main types of carbon markets: mandatory (compliance) and voluntary (VCM). While mandatory markets are regulated by mandatory emission reduction frameworks, Voluntary carbon markets (VCMs) have existed for decades, but have not yet reached their full potential. VCMs allow businesses and individuals to voluntarily generate, sell, and purchase carbon credits. These credits represent one tonne of carbon dioxide equivalent reduced or removed from the atmosphere. Purchases are often motivated by social responsibility goals, anticipation of future regulations, or speculation. VCMs provide a flexible mechanism for financing projects that reduce or remove GHGs.

Despite its potential, the current VCM landscape is fragmented and complex. Key challenges include:

• Ensuring a positive impact on the environment: There are questions about the integrity of credits, such as whether projects actually deliver additional emission reductions (additionality), how long these reductions last (permanence), and whether there is fraud or phantom credits.
• Lack of transparency: The quality of carbon credits varies and may not be easily identified by buyers. Price transparency is also lacking, because prices are often negotiated bilaterally and depend on many factors. Transparency of financial flows to projects is also a problem.
• Mismatch between standards and accreditation bodies: There are many different standards (e.g. Verra Carbon Standard, Gold Standard, ACR), which makes it difficult to compare credits and creates issues with interoperability and fungibility.
• Disagreement with digitalization: Some dominant accreditation bodies have banned the tokenization of credits held in their registries, hindering the adoption of digital solutions.
• Accessibility and barriers to entry: The process of registering, validating and verifying projects is costly and complex. Purchasing credits often requires specialized knowledge and contractual arrangements, which discourages new participants, especially smaller entities.

Distributed Ledger Technology (DLT) and Tokenization Have the Potential to Transform VCM and address many of these challenges. Tokenization converts assets into digital tokens that represent ownership rights on a DLT. Every transaction on a DLT can be tracked, audited, and verified in real time, reducing the risk of fraud and increasing market efficiency.

The benefits of tokenization for VCM include:

• Increased transparency and traceability: Every transaction is recorded on the DLT, creating an immutable record. This allows credits to be tracked from creation to cancellation, reducing the risk of fraud and double-use. Tokens can carry verifiable data about environmental impact, provenance, and verification status.
• Improved accessibility: Tokenization can lower barriers to entry for smaller buyers. Fractionalization allows the purchase of smaller portions of carbon credits, which makes the market accessible to a wider range of participants, including individuals and small businesses.
• Smart contracts for automated compliance: Smart contracts can automate the processes of emissions verification, certification and compliance, thereby increasing trust and credit quality.
• Increased business efficiency: DLT can facilitate more efficient secondary trading and enable the use of tokenized credits as collateral, increasing liquidity and flexibility for buyers.

Despite the promise of tokenization, there are also obstacles. Tokenization alone will not solve the problems of standards and quality assurance. Challenges remain regarding trust, the complexity of verification, and the need to synchronize records between traditional and digital systems. Interoperability between different DLT platforms and traditional registries is also key.

Tokenized carbon markets are essential for their success cooperation between industry participants, regulators and technology providers. Creating a unified and standardized framework that supports technological innovation is key. Using DLT to improve price and quality transparency, introducing independent verification and auditable digital records, and regulatory support for education and innovation (e.g. through sandboxes) are important recommendations for further development.

Tokenization can bring greater integrity, transparency, and accessibility to VCM, but only if implemented within strong governance structures and harmonized standards. Spring

Glossary of key terms

• Additionality: An integrity criterion for carbon credits that requires projects to demonstrate that emissions would not be reduced or removed without the incentives of carbon credit revenues.
• Blockchain: A type of distributed ledger (DLT) that records transactions in blocks and chains. It is designed to be secure, transparent, and immutable.
• Carbon credit: A non-financial environmental commodity that represents one tonne of carbon dioxide equivalent reduced or removed from the atmosphere.
• Carbon Border Adjustment Mechanism (CBAM): A European Union mechanism designed to equalize carbon prices on imported goods with carbon prices on domestic goods under the EU ETS.
• Compliance Market: A carbon market driven by mandatory national, regional or international frameworks for reducing greenhouse gas emissions.
• Distributed Ledger Technology (DLT): A digital system for recording transactions in multiple places simultaneously. Blockchain is a type of DLT.
• Double Counting: A situation where the same emission reduction or removal is counted more than once, thereby undermining the integrity of the market.
• Environmental, Social, and Governance (ESG): A set of standards for corporate behavior that investors use to evaluate non-traditional factors.
• Fractionation: The process of dividing an asset into smaller, tradable units.
• Greenwashing: The practice of companies pretending to be more environmentally sustainable than they actually are.
• Greenhouse Gases (GHG): Gases in the atmosphere that absorb and emit radiation in the thermal infrared range, thereby causing the greenhouse effect (e.g. carbon dioxide, methane).
• Integrity Council for the Voluntary Carbon Market (ICVCM): An organization that sets standards for high-quality carbon credits in VCM.
• Interoperability: The ability of different systems, platforms, or blockchains to communicate with each other and exchange data.
• Legal Entity Identifier (LEI): A global standardized identifier that provides a unique identity to legal entities participating in financial transactions.
• Mitigation Outcome Interests (MOIs): Carbon forward instruments owed by the bond issuer to the MOI holder, often repaid using mitigation outcome units (MOUs).
• Mitigation Outcome Units (MOUs): Greenhouse gas emission reduction units, which are essentially carbon credits recognized under international or national verification mechanisms.
• Net Zero: Achieving a balance between the amount of greenhouse gas emissions released into the atmosphere and the amount removed.
• Durability: An integrity criterion for carbon credits, which refers to how long avoided, reduced or removed greenhouse gas emissions remain out of the atmosphere.
• Real-World Assets (RWA): Tangible or intangible assets in the traditional financial world that are tokenized on DLT.
• Registries: Platforms that record the issuance, ownership, and retirement of carbon credits.
• Smart Contracts: Self-executing contracts, in which the terms of the agreement are written directly into code.
• Tokenization: The process of converting assets into digital tokens that represent ownership rights on a DLT.
• Verifiable LEI (vLEI): A digitized organizational identity that serves as a secure digital equivalent of a conventional LEI.
• Verra Carbon Standard (VCS): One of the most recognized standards for voluntary carbon markets.
• Voluntary Carbon Market (VCM): A market where businesses and individuals can voluntarily buy and sell carbon credits to offset their emissions.
