Jakarta/Belém. At the opening of the 30th United Nations Framework Convention on Climate Change Conference of Parties (UNFCCC COP 30) in Belém, Brazil, on Monday, Nov. 10, Indonesia’s stock exchange operator, PT Bursa Efek Indonesia (IDX), which manages the Indonesia Carbon Exchange (IDXCarbon), held a dialogue session titled “Indonesia’s Carbon Market Outlook: Enhancing Indonesia’s Carbon Market Integrity and Transparency,” in collaboration with the Financial Services Authority (OJK) and the Ministry of Environment/National Environmental Control Agency (KLH/BPLH).

The session, part of the opening agenda of the Indonesia Pavilion on the first day of COP 30, reflects Indonesia’s commitment to strengthening the integrity and transparency of its national carbon market at the global level.

“Indonesia is one of the countries with the largest carbon credit potential in the world. IDXCarbon aims to maximize this potential by ensuring transparency, reliability, and security in delivering the best solutions for carbon trading in Indonesia, fostering an orderly, fair, and efficient market. We are optimistic that global participation will continue to grow as Indonesia’s carbon market ecosystem strengthens,” said Jeffrey Hendrik, Director of Development at IDX and organizer of IDXCarbon, during the session.

During COP 30, which takes place from Nov. 10–21, 2025, the Indonesia Pavilion, organized by the Indonesian government through the Environment Ministry, serves as a platform for soft diplomacy and promotion of national climate action. The pavilion carries the theme “Accelerating Substantial Actions of Net Zero Achievement through Indonesia High Integrity Carbon,” which aligns with IDXCarbon’s vision of building a high-integrity carbon market.

Throughout COP 30, the Indonesia Pavilion is also hosting seller-buyer sessions to connect potential buyers with Indonesian carbon project developers. Supporting this initiative, IDXCarbon is showcasing various Indonesian projects already listed or in the process of being listed on the exchange.

As of October 2025, the total volume of Carbon Units recorded on IDXCarbon has reached more than 3.6 million tons of CO2e. The Indonesian carbon projects already listed include:
