How to Become an IDXCarbon Service User

IDXCarbon registration explained: user categories, documents for Indonesian and foreign companies, training and review steps for sellers and buyers.

To trade on IDXCarbon, a company registers as a Carbon Exchange Service User in one of three categories, submits corporate and financial documents, and has at least two representatives complete carbon exchange training. Foreign institutions can register directly or trade through an Indonesian user that is already registered.

What being a service user means

IDXCarbon is Indonesia’s OJK-supervised carbon exchange, run by the Indonesia Stock Exchange. Only registered service users can place orders, settle trades or retire units. Registration gives you an exchange account linked to your registry account, so that units you buy or sell move between registry holdings when trades settle. Under POJK 10/2026, traded units must be recorded in SRUK.

Who it applies to: the three user categories

A forest-carbon developer registers as a Project Developer. A corporate buyer with no cap registers as a Non-Compliance Company. Choose the category carefully, because it determines what you can trade.

What registration requires

The official route is the Carbon Exchange Service User Registration Form, or an email to the exchange support desk ([email protected]). A third-party practical guide lists the documents typically requested. The exchange may change these, so confirm the current list before you start.

Indonesian entities typically provide:

• the registration form and a signed, stamped statement letter;
• articles of association (AD/ART), deed of establishment and the related ministry approval;
• tax ID (NPWP) and business registration number (NIB);
• a beneficial-owner list;
• at least one year of financial statements;
• bank account and registry account details.

Foreign companies registering directly typically provide:

• deed of establishment and business registration number;
• a Legal Entity Identifier (LEI) with proof of registration;
• one year of financial reports;
• bank account details.

Representatives and training

At least two company representatives must complete carbon exchange (PBK) training and use company-domain email addresses. The company then submits appointment letters, identity documents, photos and the training certificates.

Review and approval

The same guide reports account review and approval taking roughly five days plus five days once documents are complete. We have seen no official service-level commitment, so plan for longer if your documents need translation or legalisation.

What it means for forest-carbon developers

Registering on IDXCarbon is the last step, not the first. Before you have anything to sell, the project must issue SPE-GRK under the national framework. In forestry that follows the Ministry of Forestry’s procedure in Permenhut 6/2026: mitigation activity, measurement and calculation, validation and verification, recording in the national system, then trading.

Practical points for developers:

• Entity and land rights first. The registering entity should match the entity that holds the project rights. Mismatches between the licence holder, the community partner and the exchange account cause delays. See who owns the carbon.
• Community projects need a registered partner. Permenhut 6/2026 requires community projects to work with registered partners. Decide early which party will hold the exchange account.
• Have monitoring data ready. Buyers on the Marketplace or Negotiated Market will ask for project evidence beyond the listing.

What it means for buyers

For a Non-Compliance Company, registration lets you buy and retire SPE-GRK directly, with the retirement recorded through the exchange. For foreign buyers, direct registration gives control; trading through an Indonesian intermediary is faster if you only need occasional volumes.

Registration does not tell you whether a unit can be counted towards an international claim. If you need a unit authorised for international transfer with a corresponding adjustment, confirm that separately.

Preparing your application

Collect corporate documents, recent financial statements and bank details before you start, and choose your two trained representatives early, because the training step often sets the timeline. Foreign entities should obtain or renew their LEI first. If you only need occasional purchases, compare the cost of registering with the option of buying through an existing Indonesian service user.

Open questions

• Document list changes. POJK 10/2026 and OJK’s technical rules (PADK 6/2026) may change onboarding requirements. Read the current exchange guidance.
• Registry account linkage. With SRUK replacing SRN-PPI for exchange-traded units, check how your registry account is opened and linked.
• Fees. We have not verified the current fee schedule for registration, trading or retirement; ask the exchange directly.
