The tonne is measured under an approved methodology, checked by an independent auditor under a carbon crediting standard, and recorded with a unique serial number in a registry. When a company, airline or government uses the credit to back a claim or meet an obligation, the credit is retired, which takes it out of circulation permanently so nobody can count it again.\n\n![The life cycle of a carbon credit, from project activity through methodology, validation, monitoring, verification, issuance and transfer to retirement](/blog-images/carbon-removal/what-is-carbon-credit.svg)\n\nCarbon credits sit behind many business claims, from \"carbon neutral\" shipping to net-zero pledges, and behind the obligations airlines carry under CORSIA. This guide sets out what a carbon credit is, what it actually represents, how one comes into existence, who uses them and why, how the picture differs across the UAE, Saudi Arabia, the United States, Europe and India, and how to tell a credible credit from a weak one.\n\nWhere a topic deserves more depth, we summarise it and link to a dedicated guide.\n\n## What Is a Carbon Credit, in Plain Terms?\n\nA carbon credit is a unit of account for climate action. It turns a physical outcome, a tonne of greenhouse gas that did not reach the atmosphere or was taken back out of it, into a record that can be owned, sold and finally used.\n\nThree ideas sit at the core of the definition:\n\n- **One credit equals one tonne of CO2e.** Greenhouse gases other than carbon dioxide, such as methane and nitrous oxide, are converted into carbon dioxide equivalent using global warming potentials. A project that destroys methane therefore earns credits in CO2e terms, not in tonnes of methane. Our guide to [what CO2e means](/blog/what-is-co2e-carbon-dioxide-equivalent/) explains the conversion.\n- **The tonne must be real, measured and verified.** A credit is only as good as the evidence behind it. Credits are issued under carbon crediting standards that set rules for measurement, auditing and record keeping. The main programmes are compared in our guide to [carbon credit standards](/blog/carbon-credit-standards-explained/).\n- **The credit lives in a registry and is used only once.** Every credit has a serial number in an electronic registry. When it is used to support a claim or meet an obligation it is retired (some systems say cancelled), and that retirement is public and final.\n\nA carbon credit is not a permit to pollute, nor a share in a project. It is a certificate of a specific environmental outcome with a defined owner at every point in its life.\n\n### Carbon Credits Versus Carbon Allowances\n\nPeople often use \"carbon credit\" loosely for anything traded in a carbon market. Strictly, there are two different instruments:\n\n| Feature | Carbon credit (offset) | Carbon allowance |\n|---|---|---|\n| What it represents | One tonne of CO2e reduced or removed by a project | Permission to emit one tonne under a capped scheme |\n| Who creates it | A crediting programme, after verification of a project | A government or regulator, as part of a fixed cap |\n| Where it comes from | Activities outside the capped sector (or outside a company's own operations) | The overall emissions budget of a trading scheme |\n| Typical examples | Verra, Gold Standard, Article 6 credits, CORSIA eligible units | EU ETS allowances, California and RGGI allowances |\n| Proof required | Baseline, additionality, monitoring and third-party verification | Legal allocation or purchase at auction |\n\nThe distinction matters because the rules, prices and claims attached to each are different. We return to it in the sections on compliance markets and the EU ETS below.\n\n## What Does a Carbon Credit Represent?\n\nWhen you hold a carbon credit, you hold a registry entry with a set of attributes. Understanding those attributes is the quickest way to understand what you are buying.\n\n| Attribute | What it tells you | Why it matters |\n|---|---|---|\n| Tonne of CO2e | The quantity of climate benefit (always one tonne per credit) | The basic unit for all claims and obligations |\n| Project ID and name | Which activity produced the credit | Lets you inspect the project documents and audit reports |\n| Methodology | The rulebook used to calculate the tonnes | Some methodologies are more conservative and trusted than others |\n| Vintage | The year in which the reduction or removal took place | Many buyers and schemes accept only recent vintages |\n| Serial number | A unique identifier within the registry | Prevents the same tonne being sold or counted twice |\n| Crediting programme | The standard that issued it, such as Verra or Gold Standard | Determines rules, safeguards and eligibility for schemes like CORSIA |\n\n### The Vintage\n\nThe vintage is the year the emission reduction or removal happened, not the year the credit was issued or sold. A cookstove project might monitor results for 2023, be verified in 2024 and have its credits issued in 2025; those credits are still 2023 vintage. Schemes such as CORSIA set eligible vintage windows, and many corporate buyers prefer recent vintages because older credits can come from projects using methodologies that have since been tightened.\n\n### The Serial Number\n\nSerial numbers are what make a credit a distinct asset rather than a general promise. A block of credits is usually described by a serial number range, and every transfer, retirement or cancellation moves a specific range. If someone offers you credits but cannot show serial numbers in a recognised registry, you are not yet looking at a carbon credit. Our comparison of [carbon credit registries](/blog/carbon-credit-registries-compared/) explains how the main registries record this.\n\n### Retirement\n\nRetirement is the moment a credit is used. The holder instructs the registry to retire a quantity of credits, typically naming the beneficiary and the purpose, for example \"retired on behalf of Company X for its 2025 Scope 1 emissions\". Once retired, the credit can never be sold or used again, and the retirement is visible on the public registry. A credit that has been bought but not retired supports no claim at all.\n\n## How Is a Carbon Credit Created?\n\nCarbon credits are not created by buying something or planting a single tree. They come from a structured process run under a crediting programme. The steps below are typical across major standards, although the names and order vary slightly.\n\n1. **Project design.** A developer identifies an activity that will reduce, avoid or remove emissions, such as capturing landfill methane, distributing efficient cookstoves, restoring mangroves or producing biochar. The developer writes a project design document setting out the boundary, the expected tonnes and the risks.\n2. **Methodology selection.** The project applies an approved methodology, which defines the baseline (what would have happened without the project), how to test additionality, how to account for leakage, and what must be monitored. Additionality, the requirement that the activity would not have happened without carbon finance, is one of the most important tests; see our explainer on [additionality in carbon credits](/blog/additionality-in-carbon-credits-explained/).\n3. **Validation.** An independent auditor, usually called a validation and verification body, reviews the design against the methodology and the standard's rules. The project is then registered with the programme.\n4. **Monitoring.** Once operating, the project collects data according to its monitoring plan: fuel use, gas flow meters, survey results, satellite imagery, laboratory samples, or whatever the methodology requires.\n5. **Verification.** For each monitoring period, an auditor checks the data and calculations and confirms how many tonnes were actually achieved. Verification can result in fewer credits than the developer expected.\n6. **Issuance.** The programme issues credits into the developer's registry account, one credit per verified tonne, each with a serial number. Some programmes deduct a share into a buffer pool to cover the risk of future reversals, especially for forestry and other nature-based projects.\n7. **Transfer and sale.** The developer sells credits directly, through brokers, exchanges or marketplaces. Ownership moves between registry accounts. A credit may change hands several times.\n8. **Retirement.** The final user retires the credit against a specific claim or obligation, and it leaves circulation for good.\n\nFrom first idea to first issuance often takes one to three years, which is why forward purchase agreements are common. If you want the practical buying process rather than the creation process, see our [guide to buying carbon credits](/blog/how-to-buy-carbon-credits-guide/).\n\n## Avoidance, Reduction and Removal Credits\n\nNot all tonnes are the same kind of tonne. The market now distinguishes clearly between credits that stop emissions from happening and credits that take carbon dioxide out of the air.\n\n| Type | What happens | Typical project examples | Main considerations |\n|---|---|---|---|\n| Avoidance | Emissions that would have occurred are prevented | Avoided deforestation (REDD+), renewable power displacing fossil generation in some grids | Highly dependent on a credible baseline; risk of over-crediting |\n| Reduction | Emissions from an existing source are cut | Landfill gas and methane destruction, efficient cookstoves, industrial gas abatement, energy efficiency | Usually easier to measure; additionality must still be shown |\n| Removal (nature-based) | Carbon dioxide is absorbed and stored in biological systems | Afforestation and reforestation, mangrove and seagrass restoration, soil carbon | Storage can be reversed by fire, disease or land-use change; buffers and long monitoring needed |\n| Removal (engineered or hybrid) | Carbon dioxide is captured and stored in stable forms | Biochar, direct air capture with storage, bioenergy with carbon capture, enhanced rock weathering | Longer durability; usually higher cost and smaller supply |\n\nAvoidance and reduction credits have historically made up most of the voluntary market. Removal credits are growing in importance because net-zero frameworks expect companies to neutralise any residual emissions with removals rather than avoidance. Our hub guide to [carbon removal credits](/blog/carbon-removal-credits-explained/) compares the removal types on durability and measurement, and our guide to [biochar carbon credits](/blog/biochar-carbon-credits-explained/) covers one of the fastest-growing durable options.\n\nType is one input to quality, not a substitute for checking it: a well-measured methane destruction credit can be more trustworthy than a poorly monitored tree-planting credit.\n\n## Compliance Versus Voluntary Carbon Markets\n\nCarbon credits are traded in two broad settings.\n\n**Compliance markets** are created by law. A government caps emissions in certain sectors or sets intensity targets, and covered companies must surrender allowances or eligible credits equal to their emissions. Some compliance schemes accept a limited quantity of offset credits; others accept none. CORSIA, the aviation scheme run through the International Civil Aviation Organization, is often grouped with compliance markets because airline obligations are enforced through national authorities.\n\n**The voluntary carbon market** covers credits bought by companies, organisations and individuals who are not legally required to buy them. They use credits to support climate claims, to contribute to climate finance beyond their own value chain, or to meet expectations from customers and investors. The rules here come from crediting programmes and integrity initiatives rather than from statute. Our explainer on [the voluntary carbon market](/blog/what-is-the-voluntary-carbon-market/) goes into how it works.\n\n| | Compliance market | Voluntary market |\n|---|---|---|\n| Why people buy | Legal obligation | Own targets, claims, stakeholder expectations |\n| Main instrument | Allowances, plus limited offsets where permitted | Carbon credits from independent programmes |\n| Rules set by | Governments and regulators | Crediting programmes, integrity bodies, buyer policies |\n| Penalties for shortfall | Fines and enforcement | Reputational and contractual risk |\n| Examples | EU ETS, California, RGGI, CORSIA obligations | Verra, Gold Standard, ACR, Climate Action Reserve, Puro.earth credits used for corporate claims |\n\nThe boundary is increasingly blurred. Voluntary-market credits can become eligible for compliance use, for example as CORSIA eligible emissions units, and governments are building their own crediting systems under Article 6. For a fuller comparison, see [voluntary vs compliance carbon markets](/blog/voluntary-vs-compliance-carbon-markets/).\n\n## Who Uses Carbon Credits and Why?\n\n### Companies Making Voluntary Claims\n\nA common, credible approach is to measure emissions across Scopes 1, 2 and 3, cut them as far as practical, and then use carbon credits for emissions that cannot yet be eliminated, or as additional climate finance beyond the value chain. Credits do not replace reductions. Frameworks such as the Science Based Targets initiative do not allow credits to count towards near-term reduction targets, and regulators in several regions are tightening rules on \"carbon neutral\" marketing claims. Our guides to [Scope 1, 2 and 3 accounting](/blog/ghg-accounting-scope-1-2-3-explained/) and [carbon neutral vs net zero](/blog/carbon-neutral-vs-net-zero/) explain how credits fit into a credible claim.\n\n### Airlines Under CORSIA\n\nThe Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) requires aeroplane operators on international routes between participating states to offset the growth in their emissions above a baseline. They do this by cancelling CORSIA eligible emissions units: credits from programmes approved by ICAO, of eligible vintages, and, for the first phase from 2024, with host country authorisation and evidence of a corresponding adjustment so the same tonne is not also counted towards that country's national target. That combination makes CORSIA-eligible credits a distinct and usually more expensive segment. Our [complete guide to CORSIA carbon credits](/blog/corsia-carbon-credits-complete-guide/) covers eligibility, timing and sourcing in depth, and our [CORSIA knowledge base entry](/knowledge-base/what-is-corsia/) gives a short summary.\n\n### Governments Under Article 6\n\nArticle 6 of the Paris Agreement lets countries cooperate on emission reductions. Under Article 6.2, one country can transfer mitigation outcomes to another, which counts them towards its own nationally determined contribution; the selling country applies a corresponding adjustment so the tonne is not claimed twice. Article 6.4 creates a centralised crediting mechanism supervised by the United Nations, which is the successor to the Clean Development Mechanism. See our explainer on the [Article 6 Paris Agreement rules](/blog/article-6-paris-agreement-explained/) and the knowledge base note on [corresponding adjustments](/knowledge-base/corresponding-adjustments-article-6/).\n\n## Carbon Credits Around the World\n\nRules on carbon credits differ by country. The summaries below reflect publicly reported information at the time of writing; regulations in this area change quickly, so check the official text or take advice before relying on any detail.\n\n### United Arab Emirates\n\nThe UAE has moved from a purely voluntary approach towards a formal national framework.\n\n- **Federal climate law.** Federal Decree-Law No. 11 of 2024 on the Reduction of Climate Change Effects was issued in 2024 and is widely reported to have entered into force on 30 May 2025, with a period for entities to come into compliance. It applies to public and private entities, including those in free zones, and introduces requirements to measure, report and reduce greenhouse gas emissions.\n- **National Register for Carbon Credits.** A national register established by Cabinet resolution and overseen by the Ministry of Climate Change and Environment is intended to support the registration, tracking and trading of carbon credits in the UAE, in line with Article 6. Reported coverage indicates that larger emitters, above a published annual emissions threshold, must register, while smaller entities may join voluntarily. Thresholds and deadlines should be confirmed against current ministry guidance.\n- **AirCarbon Exchange (ACX) in Abu Dhabi.** ACX operates a regulated carbon exchange and clearing house in Abu Dhabi Global Market (ADGM), where the Financial Services Regulatory Authority recognised it as an investment exchange and clearing house and treats carbon credits as a regulated spot commodity. Mubadala has reported a strategic stake in ACX.\n\nFor UAE companies, emissions reporting is becoming a legal matter rather than a voluntary one. Aviation groups based in the region also have CORSIA obligations; see our page on [CORSIA services in the UAE and Middle East](/services/corsia-services-uae-middle-east/).\n\n### Saudi Arabia\n\nSaudi Arabia's Public Investment Fund and Saudi Tadawul Group set up the **Regional Voluntary Carbon Market Company (RVCMC)** in Riyadh in 2022 to develop a voluntary carbon market for the Middle East and North Africa. The company has run several large carbon credit auctions, including one held in Nairobi in 2023, with buyers reported to include major Saudi corporates, and announced a carbon credit trading platform around COP29 in late 2024. The credits sold have largely come from international projects.\n\n### United States\n\nThe US has no national carbon price, but it has well-established regional compliance schemes and a large voluntary market.\n\n- **California's cap-and-trade programme**, run by the California Air Resources Board and linked with Québec, covers major sources across power, industry and fuels. In 2025 the state extended the programme to 2045 and renamed it cap-and-invest. Covered entities may use a limited share of compliance offset credits, reported as 6 per cent of their obligations from 2026, issued under the state's own offset protocols.\n- **The Regional Greenhouse Gas Initiative (RGGI)** is a cap-and-trade programme for power-sector emissions across a group of north-eastern and mid-Atlantic states. Its main currency is allowances, sold mostly at auction, and membership has changed over time.\n- **The voluntary market** in the US is large and diverse, with registries such as ACR and the Climate Action Reserve alongside Verra, and strong demand from corporate buyers. Federal guidance and state-level consumer protection rules increasingly shape how companies can describe offset-backed claims.\n\nUS-based airlines and operators also have CORSIA obligations on international flights; see our page on [CORSIA services in the United States](/services/corsia-services-united-states/).\n\n### European Union: Allowances, Not Credits\n\nThe **EU Emissions Trading System (EU ETS)** is the largest compliance carbon market in the world, but it runs on allowances (EU Allowances, or EUAs), not on project credits. Before 2021, participants could use limited quantities of international credits from the Kyoto mechanisms; since the current phase began in 2021, international credits cannot be used for EU ETS compliance. In 2025 the European Commission proposed a 2040 climate target that would allow a limited use of high-quality international credits aligned with Article 6 towards the EU's overall goal, while keeping them out of the ETS itself; that proposal was still going through the EU legislative process when reported.\n\nFor European companies, this means compliance and voluntary activity are separate: EUAs cover regulated emissions, and voluntary carbon credits are used for claims beyond regulation, where consumer protection rules on green claims are tightening. Flights within Europe are covered by the EU ETS, while CORSIA applies to many international flights; our comparison of [CORSIA, the EU ETS and the voluntary market](/blog/corsia-vs-eu-ets-voluntary-market/) sets out the overlap.\n\n### India\n\nIndia is building a national market under the Carbon Credit Trading Scheme (CCTS), with a compliance mechanism for energy-intensive sectors and an offset mechanism for voluntary projects, administered by the Bureau of Energy Efficiency; see our explainer on [India's carbon market and the CCTS](/blog/indian-carbon-market-ccts-explained/).\n\n## A Worked Example: From Footprint to Retirement\n\nThe following example is purely illustrative. The company, numbers and choices are invented to show how the mechanics fit together, not to suggest typical results or prices.\n\n**The company.** A mid-sized Dubai logistics firm has measured its greenhouse gas footprint for the 2025 financial year:\n\n| Emission source | Scope | Tonnes CO2e |\n|---|---|---|\n| Company-owned trucks and vans (diesel) | Scope 1 | 6,200 |\n| Purchased electricity for warehouses and offices | Scope 2 | 2,300 |\n| Business travel (mainly flights) | Scope 3 | 900 |\n| Total in the claim boundary | | 9,400 |\n\n**Step 1: reduce first.** The firm already has a plan to electrify part of its van fleet and buy renewable electricity for its largest warehouse, expected to cut about 1,800 tonnes over the next two years. Credits will complement that plan, not replace it.\n\n**Step 2: decide the purpose.** The firm decides to compensate for its full 2025 boundary of 9,400 tonnes, and to describe this accurately as funding emission reductions and removals outside its value chain equal to its 2025 footprint, rather than claiming to be \"carbon neutral\" without qualification.\n\n**Step 3: set a quality policy.** It decides on:\n\n- credits from programmes with recognised integrity assessments;\n- vintages no older than five years;\n- a mix of 70 per cent reduction credits from methane capture and efficient cookstoves, and 30 per cent removal credits from biochar and reforestation;\n- a preference for projects in regions where it operates or sources from.\n\n**Step 4: source and check.** Working through a marketplace and a broker, it shortlists projects, reviews project documents, verification reports and any ratings, and confirms that the seller holds the credits in a registry account. It negotiates a purchase and receives transfer confirmations showing serial number ranges.\n\n**Step 5: retire.** The firm retires 9,400 credits in the relevant registries, naming itself as beneficiary and stating \"2025 operational emissions, Scopes 1, 2 and business travel\" as the purpose. It downloads the public retirement certificates.\n\n**Step 6: report.** In its sustainability report it shows gross emissions of 9,400 tonnes separately from the credits retired, lists the projects, credit types, vintages and serial ranges, and explains its reduction plan. It does not net the credits off its reported emissions.\n\nThe key lesson is that the credits only become a claim at the point of retirement, and the claim is only as strong as the transparency around it. Costs in an exercise like this vary widely by credit type and quality; for attributed price ranges see our guide to [carbon credit prices](/blog/carbon-credit-prices-explained/).\n\n## How to Judge a Carbon Credit's Quality\n\nBecause a carbon credit is a claim about something that did not happen, or about carbon stored out of sight, quality varies enormously. A short checklist covers most of the risk:\n\n1. **Additionality.** Would the project have happened anyway without carbon revenue? If yes, the credit adds nothing.\n2. **Conservative baseline.** Is the \"without project\" scenario realistic, or inflated to create more credits?\n3. **Robust measurement and verification.** Are the data, models and audits credible and independent?\n4. **Permanence.** For removals and forest projects, how long is the carbon stored, and how are reversals covered?\n5. **Leakage.** Does the project simply shift emissions elsewhere?\n6. **No double counting.** Is each tonne issued, claimed and used only once, including against national targets where relevant?\n7. **Social and environmental safeguards.** Are local communities consulted and benefiting, and are there harms?\n8. **Recognised programme and labels.** Is the credit from a credible standard, and does it carry relevant labels such as the ICVCM Core Carbon Principles or CORSIA eligibility?\n9. **Clear title.** Can the seller prove ownership in a registry before you pay?\n\nOur detailed [carbon credit quality assessment guide](/blog/carbon-credit-quality-assessment/) works through each point, and our articles on the [ICVCM Core Carbon Principles](/blog/icvcm-core-carbon-principles/), [carbon credit ratings](/blog/carbon-credit-ratings-explained/) and [greenwashing red flags](/blog/carbon-credit-greenwashing-red-flags/) cover the main integrity tools.\n\n## Common Misconceptions About Carbon Credits\n\n**\"A carbon credit means my emissions disappear.\"** It does not. Your own emissions still occur. A credit represents a separate tonne reduced or removed elsewhere. Good reporting shows gross emissions and credits separately.\n\n**\"Buying credits is the same as using them.\"** A purchased credit that has not been retired supports no claim. Only retirement, recorded in a registry, turns a credit into an offset claim.\n\n**\"Carbon credits are a substitute for cutting emissions.\"** Credible frameworks treat credits as a complement to reductions, not a replacement. Buyers that rely on credits instead of cutting their own emissions increasingly face criticism and, in some regions, regulatory challenge.\n\n**\"Carbon credits and carbon allowances are interchangeable.\"** Allowances are permits issued under a capped scheme; credits come from projects. Some compliance schemes accept a limited quantity of credits, many accept none, and a voluntary credit cannot normally be used for EU ETS compliance.\n\n**\"Any credit can be used under CORSIA.\"** Only CORSIA eligible emissions units from approved programmes, eligible vintages and, for the first phase, with host country authorisation and corresponding adjustments, can be used. Most voluntary market credits do not qualify.\n\n**\"Carbon credits are a tax.\"** A carbon tax is a fixed charge per tonne set by government. A carbon credit is a tradable unit whose price is set by the market. Our comparison of [carbon credits and carbon taxes](/blog/carbon-credit-vs-carbon-tax/) explains the difference.\n\n## How DSTechnoverse Helps\n\nDSTechnoverse advises carbon credit buyers and project developers, with a particular focus on aviation and CORSIA.

It is checked by an independent auditor, recorded with a serial number in a registry, and can be bought, sold and finally retired when someone uses it to back a climate claim or obligation.\n\n### What does one carbon credit represent?\n\nOne carbon credit represents one tonne of carbon dioxide equivalent reduced, avoided or removed by a registered project during a particular year, known as the vintage. The credit also records the project, methodology, crediting programme and a unique serial number, so anyone can trace where the tonne came from and whether it has already been retired.\n\n### How is a carbon credit created?\n\nA developer designs a project and applies an approved methodology. An independent auditor validates the design and the project is registered. The project then monitors its results, an auditor verifies the tonnes achieved, and the programme issues one credit per verified tonne into a registry account. The process typically takes one to three years before the first credits appear.\n\n### What is the difference between a carbon credit and a carbon offset?\n\nThe terms are often used interchangeably. Strictly, the carbon credit is the tradable certificate, while offsetting is the act of using that credit to compensate for your own emissions. A credit becomes an offset when it is retired against a specific claim. Many organisations now prefer the language of contribution or compensation rather than offsetting.\n\n### What does retiring a carbon credit mean?\n\nRetiring a carbon credit means permanently removing it from circulation in the registry so it can never be sold or used again. The retirement record normally names the beneficiary and the purpose, such as a company's annual emissions. Retirement is the step that allows you to make a claim; owning credits without retiring them supports no claim at all.\n\n### Who buys carbon credits?\n\nBuyers include companies pursuing climate targets or making product claims, airlines and aircraft operators meeting CORSIA obligations, governments trading mitigation outcomes under Article 6 of the Paris Agreement, financial institutions and traders, and individuals offsetting flights or other activities. Covered firms in some compliance schemes also buy limited quantities of offset credits where the rules allow.\n\n### Are carbon credits regulated in the UAE?\n\nThe UAE has introduced a formal framework. Federal Decree-Law No. 11 of 2024 sets emissions reporting and reduction obligations, a National Register for Carbon Credits under the Ministry of Climate Change and Environment supports the registration and trading of credits, and AirCarbon Exchange operates a regulated carbon exchange in Abu Dhabi Global Market. Specific thresholds and deadlines should be checked against current official guidance.\n\n### What is the difference between avoidance and removal credits?\n\nAvoidance and reduction credits pay for emissions that would otherwise have happened, for example by destroying methane or protecting forests from clearance. Removal credits pay for carbon dioxide that has been taken out of the atmosphere and stored, for example in new forests, biochar or underground. Net-zero frameworks increasingly expect removals for residual emissions, but both types can be credible if properly measured.\n\n### Can any carbon credit be used for CORSIA?\n\nNo. Airlines can only use CORSIA eligible emissions units, which come from crediting programmes approved by ICAO, fall within eligible vintage dates and, for the first phase from 2024, carry host country authorisation and a corresponding adjustment. Most credits traded in the voluntary market do not meet all of these conditions, which is why CORSIA-eligible units usually trade at a premium.\n\n### How do I know if a carbon credit is high quality?\n\nCheck that the project is additional, uses a conservative baseline, has independent verification, addresses permanence and leakage, avoids double counting, protects local communities and comes from a recognised programme. Labels such as the ICVCM Core Carbon Principles and independent ratings help, but they do not replace reading the project documents and confirming the seller's ownership in the registry.\n\n---\n\n**Buying credits, selling credits or facing CORSIA?** DSTechnoverse advises carbon credit buyers, project developers and aircraft operators, with [CORSIA services in the UAE and Middle East](/services/corsia-services-uae-middle-east/) and [in the United States](/services/corsia-services-united-states/).
