Xange.com, Aptos Labs and Decibel Foundation Partner to Launch the First On-Chain Standard for Sovereign Mitigation Data
The Immutable Metadata Digital Certificate (IMDC) brings tradeable, verifiable data to a $100 billion-plus pipeline of sovereign Internationally Transferred Mitigation Outcomes under the Paris Agreement.
ZURICH, Switzerland, May 6, 2026 /PRNewswire/ -- At Climate Week Zurich, Xange.com, a Luxembourg-based environmental intelligence and market infrastructure company, today announced a partnership with Aptos Labs and Decibel Foundation to launch the Immutable Metadata Digital Certificate (IMDC), a tradable data token that brings sovereign-grade environmental data on-chain. As Article 6.2 of the Paris Agreement moves from bilateral cooperation arrangements toward operational markets, the IMDC introduces a standardised, verifiable record for sovereign mitigation data that every market participant can independently check. For the first time, sovereign governments are bringing treaty-regulated data on-chain, and are choosing the highest performance infrastructure to do it.
Each IMDC is a cryptographically verifiable certificate representing the official data record of a mitigation outcome, including dMRV verification data, methodology identifiers, and lifecycle status. IMDCs are issued through Xange.com's Global Environmental Market Infrastructure Solutions (GEMIS), a policy-driven technology framework for sovereign environmental market participation.
The first IMDC programme covers a $100 billion-plus pipeline of sovereign Internationally Transferred Mitigation Outcomes (ITMOs) identified by Xange.com, spanning forest, nature-based, and renewable energy programmes in countries that have signed Article 6.2 bilateral cooperation arrangements.
The launch lands as institutional tokenisation of real-world assets crossed $27.5 billion on-chain in Q1 2026, up 263% year-on-year.
Core components of the partnership include:
- Xange.com as the issuance and dMRV layer, minting IMDCs from sovereign-grade data captured through its digital monitoring, reporting, and verification systems.
- Aptos as the verification layer, providing a neutral, public ledger for IMDC issuance and lifecycle events, on a chain already hosting approximately $1 billion in institutional real-world assets.
- Decibel as the on-chain market layer, providing institutional and qualified counterparties with access to tradeable IMDCs with full lifecycle transparency.
- Independent third-party ITMO registry and settlement under GEMIS, with sovereign ITMO registry, custody, and settlement functions delivered through a digital platform integrated into the Xange.com GEMIS framework
"Sovereign climate data has requirements that most blockchain infrastructure simply cannot meet. You need institutional-grade throughput to handle the volume of a global market, sub-second finality so that settlement matches the pace of institutional finance, and an audit trail that can hold up to scrutiny from treaty bodies and auditors decades from now. Aptos is the only public network operating today that combines the performance, finality, and institutional adoption this category demands, and that's why Aptos is the verification layer for what we expect to become the largest sovereign asset program in the tokenization market," said Avery Ching, CEO of Aptos Labs.
"Verified data is itself a valuable asset. Mitigation-rich countries hold trillions of dollars in mitigation outcomes, but that value cannot reach international climate finance without trustable data and infrastructure. IMDCs turn the verified data behind those outcomes into a tradeable instrument every market participant, from sovereign sellers to compliance buyers, can rely on," said Esteban van Goor, CEO and Founder of Xange.com.
