As global efforts toward carbon neutrality continue to accelerate, carbon markets are increasingly moving toward digitalization and standardization. Traditional carbon credits have long relied on paper certificates and centralized records, facing challenges in transparency, operational efficiency and verifiability. Recently, Carbon Removal Credit (CRC) officially launched its Carbon Asset NFT framework, introducing on-chain digital identity mechanisms for carbon credits through blockchain technology. This initiative explores technical avenues to improve transparency, traceability and data consistency in the management of carbon assets.
According to CRC, the core of its Carbon Asset NFT framework lies in mapping carbon emissions reductions consistent with key international standards – such as VCS, Gold Standard and ISO 14064 – into on-chain NFT assets. Each NFT corresponds to a specific volume of emissions reductions and records key on-chain metadata, including project origin, certification body, reduction volume and geographic information. This approach transforms carbon credits from traditional centralized records into digital assets with unique on-chain identifiers, allowing for easier querying and verification by multiple stakeholders.
The CRC said the introduction of digital identities for carbon assets via NFTs represents one of its technical practices to improve transparency and traceability. The immutability of blockchain technology helps reduce the risk of unilateral data modification, allowing project information and asset status to be stored and displayed on-chain more consistently, providing clearer data references for market participants.
On the CRC platform, Carbon Asset NFTs can be exchanged and transferred in a decentralized environment. Users can purchase and transfer carbon assets and use the “Withdraw” feature to mark corresponding NFTs as being used for carbon offsetting. These actions are recorded on-chain via smart contracts, generating searchable withdrawal records that reflect the usage status of each carbon asset. This mechanism helps reduce the risk of duplicate use and provides companies with verifiable on-chain records of carbon neutrality and ESG information.
At the same time, CRC is exploring technical integration between off-chain surveillance data and on-chain assets. Using Oracle technology and Internet of Things (IoT) devices, monitoring data from selected carbon reduction projects can be synchronized on-chain to support the presentation of the project’s operational status. Combining off-chain data with on-chain assets helps improve the completeness of carbon asset information, while continuing to work in coordination with existing certification and audit frameworks.
From a technical application point of view, the introduction of carbon credits in the form of NFTs contributes to improving the identifiability and management of carbon assets in digital environments, providing new tools for the digital management of carbon markets. Companies, investors and relevant institutions can use CRC’s on-chain mining tools to query basic asset information, transaction records and retirement status, thereby improving the traceability of carbon asset utilization processes.
The CRC also noted that the Carbon Asset NFT framework introduces additional technical possibilities for product design and application scenarios in carbon markets. Within existing compliance and regulatory frameworks, carbon credit tokenization can support more flexible digital management approaches, providing fundamental infrastructure for exploring new operating models and system integrations.
To date, the Carbon Removal Credit (CRC) has connected to several carbon reduction projects and continues to advance on-chain digital management practices for carbon assets. The CRC said it will continue to improve data standardization and on-chain management mechanisms under existing certification systems and regulatory frameworks, providing technical support at the infrastructure level for the ongoing digitalization of carbon markets.
