Corporate emissions targets are getting harder to meet through operational efficiency alone, especially for industries where decarbonization along the value chain takes years, not quarters. Energy-intensive sectors, agribusiness, and manufacturers face the uncomfortable reality that scope 2 and scope 3 emissions cannot be eliminated overnight, no matter how well-designed the internal sustainability program.
Meanwhile, regulatory pressure is intensifying. Indonesia’s carbon market framework under Presidential Regulation No. 110 of 2025 (Perpres 110/2025) is tightening compliance obligations, and global buyers are scrutinizing the integrity of every carbon credit their suppliers and partners claim. A single low-quality offset in a corporate portfolio can unravel years of ESG credibility in a matter of one audit cycle.
Understanding what is a carbon credit and how it actually works is no longer optional for ESG managers, policymakers, or sustainability teams. This guide breaks down the mechanics clearly, with a focus on what makes a credit credible enough to withstand scrutiny in today’s market.
What is a Carbon Credit?
A carbon credit is a tradable certificate representing the reduction, avoidance, or removal of one metric tonne of carbon dioxide equivalent (CO2e) from the atmosphere. It functions as a unit of account in both voluntary and compliance carbon markets, allowing entities to offset emissions they cannot yet eliminate through internal measures.
The concept is grounded in the principle that greenhouse gas emissions are a global problem, so a tonne reduced anywhere on the planet carries equivalent climate value. What is a carbon credit in practical terms is therefore both a climate instrument and a financial asset, one whose value depends directly on how rigorously it was produced and verified.
It is important to distinguish between a carbon credit and a carbon allowance. Allowances are typically issued by regulators under cap-and-trade systems, while credits are generated by projects that actively reduce or remove emissions. Both can be traded, but they operate under different rules and serve different strategic purposes for businesses.
How Are Carbon Credits Created?
Carbon credits do not emerge automatically from a sustainability initiative. They require a structured process that converts real-world emission reductions into standardized, auditable units that the market can trust and trade with confidence.
1. Measurement and Verification (MRV)
The foundation of any credible carbon credit is a robust MRV framework, which stands for Measurement, Reporting, and Verification. Project developers must first establish a baseline, the emissions trajectory that would have occurred without the project, and then measure actual reductions against that baseline using methodologies approved by a recognized international carbon certification standard.
Verification is conducted by an accredited independent verification body (VVB), which reviews all data, site conditions, and documentation before any credit can be issued. This step is non-negotiable because it ensures the claimed reductions are real, additional, permanent, and not double-counted elsewhere in the system.
2. Registration and Credit Issuance
Once verification is complete, the project is registered in a publicly auditable carbon registry, which assigns unique serial numbers to each credit issued. This registry record serves as the chain of custody, allowing buyers, regulators, and auditors to trace every credit back to its originating project and confirm it has not been sold twice.
After issuance, credits can be held for internal offsetting purposes or traded on secondary market venues and aggregator platforms. Retirement, the act of permanently cancelling a credit to claim its climate benefit, is recorded in the same registry and is visible to all parties, ensuring full transparency throughout the lifecycle.
Benefits of Carbon Credits
Carbon credits serve multiple functions beyond simple offsetting. They create measurable incentives for investment in climate solutions across several dimensions of business and policy impact.
1. Reducing Greenhouse Gas Emissions
At their core, carbon credits represent real tonnes of CO2e that have been reduced or removed from the atmosphere, contributing directly to national and global decarbonization goals. For corporates with residual emissions that cannot yet be eliminated, they provide a bridge toward net-zero while longer-term solutions are developed and scaled.
2. Encouraging Sustainable Business Practices
When businesses participate in carbon markets, they are financially rewarded for adopting cleaner technologies, better land management, and lower-emission production methods. This creates a market signal that sustainable practices are not just ethically desirable but economically rational, which accelerates adoption beyond what regulation alone can achieve.
3. Providing Financial Incentives
For project developers, carbon credits generate a revenue stream that can make climate-positive activities commercially viable. Reforestation, regenerative agriculture, waste-to-energy, and carbon removal projects that might otherwise be financially unviable become investable when the carbon value they generate can be monetized through verified credits.
4. Supporting National and Global Emission Targets
Countries can leverage carbon markets to mobilize private capital toward their nationally determined contributions (NDCs) under the Paris Agreement. In Indonesia’s case, the carbon market framework established under Perpres 110/2025 explicitly links market mechanisms to the country’s NDC commitments, creating a formal pathway for corporate action to contribute to national targets.
5. Improving Corporate Reputation and Compliance
For companies operating across international supply chains, holding verified carbon credits under a recognized standard signals credibility to buyers, investors, and regulators. As scrutiny of greenwashing increases globally, the quality and provenance of a company’s carbon portfolio have become indicators of overall ESG governance maturity.
How to Calculate Carbon Credits
Calculating carbon credits is not a matter of estimation or approximation. It follows a disciplined sequence of steps that must all be completed before a single tonne of CO2e can be registered and issued as a tradable credit.
1. Determining Emission Sources and Baseline
The first step is identifying all emission sources within the project boundary and establishing a credible baseline, the counterfactual scenario that shows what emissions would have been without the project. This baseline must be supported by historical data, regional benchmarks, or approved methodologies that prevent developers from inflating the apparent size of their reductions.
2. Measuring Emission Reductions
Actual emissions during the project period are then measured using standardized protocols appropriate to the project type. For biochar carbon removal projects, this includes measuring the carbon content of the biochar produced, the stability of that carbon over time, and the lifecycle emissions associated with feedstock sourcing and production.
3. Calculating the Emission Difference
The verified emission reduction or removal is calculated as the difference between the baseline scenario and actual project emissions, adjusted for any leakage, which refers to emissions displaced rather than eliminated. Only net reductions that pass additionality tests, confirming they would not have occurred without the carbon finance, are eligible for credit issuance.
4. Verification by an Independent Party
Before any credits are issued, all calculations and supporting data must be reviewed and confirmed by an accredited independent verification body. This third-party audit is the mechanism that prevents self-reporting errors, methodological shortcuts, or deliberate misrepresentation from entering the carbon market as certified units.
5. Issuance and Registration of Carbon Credits
Upon successful verification, the corresponding credits are issued and recorded in a publicly auditable carbon registry. Each credit receives a unique identifier tied to the project, vintage year, and methodology used, giving downstream buyers full traceability and assurance that the credit has not been retired or traded elsewhere.
Carbon Credit Potential in Indonesia
Indonesia holds one of the world’s most significant natural carbon reservoirs, with peatlands, tropical forests, coastal mangroves, and extensive agricultural land collectively representing hundreds of millions of tonnes of potential carbon sequestration. The country’s NDC under the Paris Agreement targets a 31.89 percent unconditional emissions reduction by 2030, rising to 43.20 percent with international support, according to Indonesia’s Updated NDC submitted to the UNFCCC.
The domestic carbon market framework, now anchored by Perpres 110/2025, creates a formal structure for translating this natural potential into verifiable, tradable carbon credits. Businesses operating within Indonesia’s jurisdiction, particularly those in forestry, agriculture, energy, and manufacturing, are increasingly expected to engage with this framework both as a compliance requirement and as a strategic opportunity.
Beyond compliance, Indonesia’s carbon market represents a significant commercial frontier. As international demand for high-integrity, nature-based, and technology-based carbon removal credits continues to grow, Indonesian project developers and corporates who invest early in robust carbon credit MRV systems will be better positioned to access both domestic and global buyers.

Biochar as a Source of High-Quality Carbon Credits
Among the emerging categories in the voluntary carbon market, biochar carbon removal has attracted significant attention from buyers and standard-setting bodies alike. Biochar credits are distinguished by several technical characteristics that place them among the more defensible and durable credit types available today.
1. Why Biochar Is Considered Premium in the Carbon Market
Biochar achieves carbon removal by converting organic biomass into a stable form of carbon through a thermochemical process called pyrolysis. The resulting biochar has a mean residence time measured in centuries to millennia, meaning the carbon stored within it is effectively removed from the active carbon cycle for far longer than most biological sequestration pathways such as afforestation or soil carbon.
This durability directly addresses one of the most persistent integrity concerns in the voluntary carbon market, which is the risk of reversal, the possibility that stored carbon is released again due to fire, disease, land-use change, or policy failure. Because biochar’s carbon is chemically stable rather than biologically locked, it scores substantially higher on permanence metrics recognized by frameworks such as the Oxford Principles for Net Zero Aligned Offsetting.
2. Added Value from Agricultural Biomass Waste
Most biochar production in Indonesia relies on agricultural residues such as rice husks, sugarcane bagasse, palm fronds, and coconut shells, materials that would otherwise decompose or be burned openly in the field. By diverting these waste streams into biochar production, projects generate an additional layer of emission reduction on top of the sequestration benefit, specifically by preventing the methane and nitrous oxide emissions that would have resulted from open burning or anaerobic decomposition.
This dual-benefit structure, combining waste management with high-permanence carbon removal, makes biochar an attractive option for buyers seeking high-quality carbon credits that align with both the Integrity Council for the Voluntary Carbon Market’s Core Carbon Principles and the Science Based Targets initiative’s guidance on carbon removals. For project developers in Indonesia, agricultural biomass abundance creates a meaningful structural advantage in feedstock supply and cost.
Integrity Challenges in the Carbon Market and How to Address Them
The rapid growth of carbon markets over the past decade has also amplified concerns about credit quality. Academic studies and investigative analyses published between 2022 and 2024 found that a significant portion of credits issued under certain methodologies overstated actual emission reductions, raising questions about the credibility of the voluntary market as a whole.
The primary integrity risks fall into several categories: baseline inflation, where developers set an artificially high counterfactual to maximize apparent reductions; additionality failure, where projects would have happened anyway without carbon finance; permanence risk, where stored carbon is later released; and leakage, where emissions are simply displaced to outside the project boundary rather than genuinely reduced. Each of these risks requires specific methodological safeguards to detect and prevent.
The Integrity Council for the Voluntary Carbon Market’s Core Carbon Principles provide a useful benchmark for evaluating whether a given credit addresses these risks adequately. For corporate buyers, the practical implication is that price alone is a poor proxy for quality. Investing in credits with transparent MRV documentation, independent verification, and registration in a publicly auditable registry is the only reliable way to ensure a carbon portfolio can withstand scrutiny from investors, regulators, and counterparties alike.
