Klima Protocol
Open infrastructure for carbon markets.
Klima Protocol enables transparency, instant execution, and traceable impact.
"Carbon markets suffer from fragmentation, opacity, and inconsistent quality standards.
Scaling the Carbon Market
Today's carbon market spans multiple registries, methodologies, and trading venues. This diversity reflects innovation, but it can also fragment liquidity, reduce transparency, and increase transaction friction for project developers and buyers alike.
The market's ambition is clear, but it has yet to reach the scale the climate challenge demands. Achieving that scale requires clearer market signals, stronger coordination, and infrastructure that enables participants to transact more efficiently.
