Buying carbon credits in Indonesia has, until recently, been hard for international buyers to do with confidence. That is changing fast. Indonesia holds one of the largest and highest-quality nature-based carbon opportunities in Southeast Asia. Its vast tropical forests, peatlands, and mangroves store some of the densest carbon stocks on earth, and the market to access those carbon credits is finally emerging. Presidential Regulation 110/2025 has reopened international transfers, the SRUK carbon registry has launched, and Ministry of Forestry Regulation 6/2026 now sets out exactly how a forestry carbon credit is certified, exported, and adjusted.
Supply still runs ahead of demand, and around 90% of exchange buyers today are domestic. For international buyers, that gap is the opportunity. Entering now, while the rules, mechanisms, and infrastructure are still taking shape, means securing the strongest projects early and building relationships with Indonesian stakeholders ahead of competitors. As the market matures, those early buyers will already hold the supply, the local partnerships, and the groundwork that later entrants will have to scramble for.
Buying carbon credits in Indonesia means more than picking available units off a screen. It requires understanding which project types exist, which market pathway applies to your goals, which regulations govern international transfer, and how to verify that a credit represents a real, additional tonne of avoided or removed emissions. This guide walks international buyers through that process step by step, so procurement decisions rest on evidence rather than assumption.
Why International Buyers Are Buying Carbon Credits in Indonesia
Indonesia’s Natural Climate Assets
Indonesia’s advantage is physical, built on a diverse range of forest ecosystems. It holds the largest area of tropical peatland in the world, with around 14.91 million hectares of peatland and 3.44 million hectares of mangrove (close to 23% of the world’s mangrove estate). These are vast areas, and they are highly effective carbon sinks. Hectare for hectare, mangroves store roughly five to ten times more carbon than a typical tropical forest, and peatlands store more still.
The opportunity is broader than those two headline ecosystems. Forest protection and improved forest management, reforestation and agroforestry, blue carbon in coastal systems, and engineered removals such as biochar all sit within Indonesia’s addressable pipeline. To put the scale in perspective, Indonesia’s forestry carbon roadmap under Ministry of Forestry Regulation 6/2026 targets at least 48.69 million hectares of forest and 3.5 million hectares of degraded land for emission-reduction activities.
For a buyer, that breadth is the point. It means a portfolio of carbon credits can be built around the claim you actually need, whether that calls for high-density avoidance credits, durable removals, or a blend of both. Nature-based projects such as forest protection, peatland rewetting, and mangrove restoration form the core of the pipeline today, and newer methodologies are extending it into blue carbon and engineered removals.
Indonesia’s Evolving Carbon Market
Indonesia’s carbon market is still early-stage, but the scaffolding is now in place: a live national registry, a legal route for international transfer, and clear forestry-sector rules. For buyers, that translates into clearer requirements today and genuine first-mover access while trading volumes are still light. The window in which you can secure the best projects on favourable terms is open now, not indefinitely.
Understanding Indonesia’s Carbon Market Landscape
Domestic Market Infrastructure
Indonesia’s regulated domestic exchange is IDXCarbon, operated by the Indonesia Stock Exchange and authorized by the financial regulator OJK. Since opening on 26 September 2023, it has grown to more than 150, and cumulative trading value reached roughly IDR 93.81 billion as of 30 June 2026. The exchange is only one channel, though around 90% of its buyers are domestic (Reccessary, 2025), and much of the country’s high-integrity supply (especially the carbon credits international buyers want) is transacted directly with project developers rather than on the exchange. Treat IDXCarbon as the official, transparent venue for standardized domestic units, not as the whole market. Credits registered domestically are recorded in the national registry, now consolidated under the SRUK carbon unit registry.
International Carbon Markets
For buyers outside Indonesia, the key question when buying carbon credits in Indonesia is whether a credit can legally leave the country and how it will be counted. Presidential Regulation No. 110 of 2025 (Perpres 110/2025), signed in October 2025 to replace the earlier Perpres 98/2021, reopened international sales under stricter rules. The regulation draws a clear line between two kinds of units.
Corresponding Adjustment (CA) credits are authorized for international transfer under Article 6 of the Paris Agreement. When these leave Indonesia, the government subtracts the tonnes from its own national inventory so the same reduction is not claimed twice. Non-CA credits stay within Indonesia’s accounting and trade in the voluntary market without a corresponding adjustment.
This distinction decides whether a credit can count toward another country’s national target or a corporate claim made under Article 6 rules after buying carbon credits in Indonesia. International transfer requires authorization from the Ministry of Environment. Buyers should confirm a credit’s status before assuming it fits their reporting needs.
The Role of Carbon Project Developers
Not all high-integrity Indonesian carbon credits are bought on the exchange; many are sourced directly from the developers who design, register, and monitor the projects. A developer’s core job is to make sure each credit is genuinely high quality, meaning it represents a real, additional, and permanent tonne backed by sound data. In practice, that means the developer controls the three things that decide a credit’s quality: the baseline methodology (how the “without-project” scenario is estimated), the monitoring data (the on-the-ground measurements that prove the reduction actually happened), and the audit trail behind each issuance (the verifiable record a third-party auditor checks). For international buyers unfamiliar with local land tenure, permitting, and MRV requirements, a strong developer relationship is usually the fastest route to carbon credits that survive due diligence.
Meeting Stakeholder and Investor Expectations
Procurement no longer happens in separation from finance and compliance. Boards, investors, and auditors increasingly ask not just how many credits a company retired, but which projects they came from and whether the underlying data is defensible. A credible sourcing story (one that names projects, methodologies, and verification standards) is now part of the disclosure itself.
Finding the Right Carbon Credits for Your Climate Strategy when Buying Carbon Credits in Indonesia
Step 1: Define Your Carbon Credit Procurement Objectives
Decide what the credit must do before you look at what is available. A company meeting a voluntary net-zero pledge has different needs from one preparing for Article 6 compliance or CBAM-adjacent exposure. Removal credits (which take carbon out of the atmosphere) and avoidance credits (which prevent emissions that would otherwise occur) serve different claims. Set the objective, the volume, the timeframe, and the permanence requirement first. Everything downstream follows from this.
Step 2: Identify the Right Carbon Projects
Match project type to objective. Peatland and mangrove projects offer high carbon density and strong co-benefits but require rigorous hydrological monitoring. Forest protection projects carry leakage and permanence questions that must be actively managed. Emerging removal projects such as biochar offer greater permanence at higher cost. Location, methodology, and vintage all shape the risk profile, so evaluate projects individually rather than by category alone.
Step 3: Assess Project Integrity
Most buyer risk comes down to integrity. Check four things: additionality (would the reduction have happened anyway?), a defensible baseline, permanence backed by reversal buffers, and independent verification against a recognized standard. Ask for the monitoring data, not just the certificate. Two carbon credits with identical descriptions can carry very different real-world risk depending on methodology and issuance year. Independent measurement, reporting, and verification (MRV) is the evidence that separates a credible tonne from a claimed one.
Step 4: Choose the Appropriate Purchasing Pathway
There are three practical routes. Buying carbon credits in Indonesia through IDXCarbon suits standardized domestic units and offers exchange-level transparency. Buying directly from a project developer suits buyers who want specific projects, larger volumes, or forward supply. Buying credits authorized for international transfer (CA units under Article 6) suits buyers who need the reduction to count toward the NDC of the buyer’s country.
Authorization for international transfer, and the corresponding adjustment that goes with it, is a government process granted by the Ministry of Environment. It is not a label a buyer can add after the fact, so confirm a credit’s authorization status before you commit rather than assuming a voluntary (non-CA) unit can later be converted for a cross-border or Paris Agreement-aligned claim. Because authorization takes time, start that conversation early.
Step 5: Complete the Transaction and Manage Carbon Credits
Once terms are agreed, the transaction is recorded in the relevant registry (SRUK domestically, with a corresponding adjustment applied for authorized international transfers). Retire credits against the specific claim they support, and keep the serial numbers, project details, and verification records. Clean documentation is what makes a retirement defensible when an auditor or regulator asks.
Building a Long-Term Carbon Credit Procurement Strategy
One-off purchases leave buyers exposed to price spikes and supply gaps in a market this thin. A durable strategy for buying carbon credits in Indonesia does four simple things:
- Build direct relationships with a few trusted developers instead of buying anonymous units.
- Lock in future supply early through offtake or forward agreements, before projects are fully issued.
- Tie procurement to your decarbonization plan, so credits complement your emission cuts rather than substitute for them.
- Lean on experienced developers to handle the technical, regulatory, and commercial questions that keep shifting as Indonesia’s rules change.
The Bottom Line for International Buyers
Indonesia offers international buyers a rare combination: deep and varied natural carbon assets, a regulatory framework that is finally taking shape under Presidential Regulation 110/2025, and a pipeline that spans both nature-based and emerging removal projects. The opportunity is real, and the pathways to act on it now exist. Complexity remains (the infrastructure is young and implementation is still maturing), but that is precisely why successful procurement starts with understanding the landscape, selecting credible projects, and choosing the pathway that fits your claim, rather than rushing a transaction. The buyers who start buying carbon credits through direct developer relationships now will be the ones holding a resilient, defensible portfolio later, rather than credits that fail due diligence, cannot be counted toward their climate target, or carry reputational risk.
How TruCarbon Helps International Buyers Source Credible Credits
The steps above describe what strong procurement looks like. Executing them across an unfamiliar market, in a regulatory environment that changed as recently as Presidential Regulation 110/2025, is where most international buyers need a local partner on the ground.
TruCarbon is an Indonesian carbon project developer and decarbonization advisory built for exactly this. On the sourcing side, we develop and monitor nature-based and emerging carbon projects directly, which means buyers can access verified carbon credits from named projects with a full audit trail rather than anonymous units of uncertain origin. On the integrity side, our TruMRV measurement, reporting, and verification service produces the monitoring evidence that stands up to buyer due diligence and third-party audit, the same evidence Step 3 of this guide tells you to demand.
Before buying carbon credits in Indonesia, our expert team helps international buyers define procurement objectives, confirm whether credits qualify for Article 6 international transfer and corresponding adjustment, choose the right purchasing pathway, and structure long-term supply agreements. If you are evaluating Indonesia as a source of high-integrity carbon credits and want to know which projects and pathways fit your specific claim, that is the conversation we are set up to have.
Frequently Asked Questions
Can foreign companies buy carbon credits in Indonesia?
Yes. International buyers can purchase Indonesian carbon credits through the IDXCarbon exchange or directly from project developers. Credits intended to count toward another country’s national target or an Article 6 claim must be authorized for international transfer by the Ministry of Environment, with a corresponding adjustment applied under Perpres 110/2025.
What is the difference between a CA and a non-CA carbon credit?
A Corresponding Adjustment (CA) credit is authorized for international transfer, and Indonesia subtracts the reduction from its own national inventory to prevent double counting. A non-CA credit stays within Indonesia’s NDC and trades in the voluntary market without that adjustment. The distinction determines whether a credit can support a Paris-aligned or cross-border claim. It’s important to understand this before buying carbon credits in Indonesia.
How much does buying carbon credits in Indonesia cost?
Prices for buying carbon credits in Indonesia vary widely by project type, quality, and pathway, and the market is still thin, so published exchange figures are not always representative of direct transactions. Rather than relying on a headline number, buyers should price credits against project integrity, since higher-integrity credits typically command a premium and carry lower reputational risk. There is no single verified market-clearing price to cite, so confirm current pricing directly with a developer or the exchange before buying carbon credits in Indonesia.
What makes an Indonesian carbon credit high integrity?
There are four main factors: genuine additionality, a defensible baseline, managed permanence with reversal buffers, and independent verification supported by transparent monitoring data. The certificate is the starting point for due diligence, not the finish line. Check those factors of high-integrity credits before buying carbon credits in Indonesia.
Where are carbon credit transactions recorded when buying carbon credits in Indonesia?
Domestic transactions are recorded in the national carbon unit registry (SRUK). Authorized international transfers are additionally subject to a corresponding adjustment to Indonesia’s Nationally Determined Contribution under Article 6 of the Paris Agreement.
