Ecobiz.asia — Indonesia’s carbon exchange, IDXCarbon, is exploring cross-market connectivity with international carbon bourses as it seeks to widen access for Indonesian carbon credits and integrate more closely with global trading platforms.
The initiative was outlined by Ignatius Denny Wicaksono, Head of Business Development 2 Division at the Indonesia Stock Exchange (IDX), during the Indonesia’s Carbon Market Outlook session at the Global Carbon Summit Indonesia 2025 hosted by Ecobiz Asia in Jakarta on Nov. 26–27.
Denny said discussions are underway with several international exchanges, including Singapore’s Climate Impact X (CIX), to develop interoperability that would allow Indonesian-issued credits to be displayed and traded across multiple markets.
“We are exploring connectivity and interoperability with global carbon exchanges. With this collaboration, Indonesian carbon credits could be traded more widely and accessed more easily by international buyers,” Denny said.
IDXCarbon, launched in 2023, has recorded 1.6 million tonnes of CO₂e in trading volume to date, an outcome Denny described as significant, given Indonesia has yet to implement a mandatory carbon market.
Participation is growing steadily, with 144 registered users but nearly 2,000 beneficiaries, including individuals, companies, and event organizers using carbon credits for voluntary offsetting.
Denny said the exchange’s design—transparent pricing, simplified transactions and a trading fee of just 0.11%—has reduced reliance on bilateral carbon deals that can incur 10–30% brokerage costs. IDXCarbon handles both trading and clearing, eliminating the need for individual contractual negotiations between buyers and sellers.
The platform also uses a private blockchain to reduce double-counting risks and is directly integrated with Indonesia’s National Registry System (SRN), allowing users to hold and retire credits without needing a separate registry account.
International buyers, he added, have begun entering the Indonesian market through three channels: direct registration on IDXCarbon, using Indonesian subsidiaries, or leveraging local intermediaries. Cross-market trading may become an additional route once technical and regulatory integration with partner exchanges is established.
Beyond carbon trading, IDX is pushing listed companies to strengthen their decarbonization commitments by calculating and disclosing emissions, adopting green financing tools, and incorporating carbon offsetting into net-zero strategies. More than 70% of credit purchases on IDXCarbon currently come from IDX-listed companies.
Denny said IDXCarbon now features 41 existing carbon projects and is preparing a pipeline of around 90 million tonnes of CO₂e from upcoming issuances. Interested buyers can submit expressions of interest through IDXCarbon’s official channel.
“Indonesia holds one of the world’s largest carbon credit potentials. IDXCarbon aims to ensure these credits are traded transparently, securely and efficiently, helping attract more global participation in Indonesia’s green transition,” Denny said. ***
