Intercontinental Exchange launches ICE GreenTrace environmental registry for carbon markets
The world's largest environmental derivatives operator migrated 437 million carbon credits onto its new registry platform with Winrock International as launch partner.
Intercontinental Exchange, the company that runs the New York Stock Exchange and operates the world’s largest environmental derivatives markets, just rolled out a new piece of infrastructure that could reshape how carbon credits are issued, traded, and retired.
ICE GreenTrace is an environmental registry technology service designed to bring exchange-grade reliability to a market that has historically struggled with exactly that. Winrock International’s Environmental Resources Trust (ERT) signed on as the launch partner, migrating 437 million carbon credits and 40,000 documents onto the platform.
What GreenTrace actually does
GreenTrace handles the full lifecycle of environmental instruments: issuance, trading, and retirement. ICE is pitching it on four pillars: security, scalability, user-friendliness, and continuous support.
ERT manages several established programs, including ACR and ART. Moving 437 million credits is not a soft launch. That’s a full-scale migration designed to signal that the platform is ready for institutional traffic.
ICE initially disclosed plans for this registry back on January 28, 2025, with a target rollout of late 2025. The actual launch landing in June 2026 represents a modest delay, but the scope of the migration suggests ICE used the extra time to ensure the platform could handle real volume from the start.
The voluntary carbon market’s credibility problem
ICE already holds the position of the world’s largest operator of environmental derivatives markets. GreenTrace extends that dominance from the trading layer down into the registry layer, giving ICE influence over more of the carbon credit value chain.
What this means for crypto and tokenized carbon
GreenTrace operates within the framework of traditional registry technology, without integrating any blockchain-native solution. ICE has separately announced a joint venture with OKX, the major crypto exchange, to explore tokenized markets. Those two initiatives exist in parallel.
The risk is concentration. If ICE captures both the registry and exchange layers of carbon markets, it could set the rules in ways that favor its own ecosystem and limit interoperability with decentralized alternatives.
