Xange.com, Aptos Labs and Decibel Foundation have announced a partnership to launch a new on-chain standard for sovereign environmental data. The announcement was made during Zurich Climate Week.
Xange.com, an environmental market infrastructure company, introduces the Immutable Metadata Digital Certificate (IMDC). The system creates tokenized records linked to sovereign mitigation outcomes under Article 6.2 of the Paris Agreement framework.
Each IMDC acts as a verifiable digital certificate with official risk mitigation data. This includes dMRV verification records, methodology IDs, and lifecycle status information. According to the companies, governments and market participants will be able to independently verify every record in the chain.
The certificates will be issued through Xange.com’s GEMIS framework, designed for sovereign participation in environmental markets. Aptos Labs, developer of the Aptos blockchain ecosystem, will provide the public infrastructure layer for verification and lifecycle tracking.
Decibel Foundation, a digital environmental market platform, will provide institutional participants with access to tradable IMDCs and settlement tools. The partnership also includes an independent third-party registry and custody infrastructure integrated into the GEMIS system.
The first IMDC program is linked to a pipeline of more than $100 billion in Internationally Transferred Mitigation Outcomes (ITMOs). The projects include forestry, renewable energy and other nature-based programs in countries participating in Article 6.2 cooperation agreements.
