Indonesia's OJK Announces Blockchain Carbon Registry Upgrade, Launches SRUK System Integration

According to Indonesia's Financial Services Authority (OJK), on May 21, 2026, the regulator announced plans to upgrade the country's carbon exchange system by introducing blockchain-based registry technology and integrating it with the new Carbon Unit Registry System (SRUK). The initiative aims to improve transparency, efficiency, and transaction traceability in Indonesia's carbon market.

The blockchain-enabled registry is expected to reduce double-counting risks, accelerate carbon unit issuance and verification, and provide real-time access to transaction records for market participants. SRUK will operate as an integrated national platform connected directly to carbon trading exchanges such as IDXCarbon, simplifying transaction procedures and supporting broader market growth. Current carbon trading activity in Indonesia totals approximately US$6 million.
