What Is the Price of CORSIA Carbon Credits?
The CORSIA carbon credits price is not one fixed number. CORSIA Eligible Emissions Units (EEUs) trade at different prices depending on the specific unit, its crediting programme, vintage, host-country authorisation status, the supplier and the structure of the deal.
An EEU is a carbon credit that meets ICAO’s eligibility requirements for the relevant compliance period. A general voluntary carbon credit may come from a well-run project and still fail one of those requirements, so it cannot be assumed to work for CORSIA. Eligibility is set by ICAO and programme rules, not by price.
Several dated price signals give a sense of the range. They are indicators, not quotes, and they cover different instruments:
- 16 October 2026: A market report put the CORSIA Phase 1 (2024–2026) December 2026 assessment at $13.15 per tCO₂e, the highest level since April. This is a market assessment, not a completed transaction, and it does not name a programme or vintage. green
- 28 January 2026: Fastmarkets assessed Phase 1 spot credits at $19 per tCO₂e, and ICE December 2026 contracts traded between $14.50 and $16 in the preceding days. This is historical. fastmarkets
- ICAO analysis (2025 Periodic Review): Based on limited data, average prices for emissions units during the first phase were estimated at $10 to $40 per tCO₂. europa
These figures differ because they measure different things at different dates. Prices may change with supply, demand and eligibility conditions. For a real purchase, request comparable quotes for the exact units you need.
What Factors Affect CORSIA Carbon Credits Pricing?
Several factors interact, and none works the same way for every credit.
Eligibility and programme. Units must come from a programme approved by the ICAO Council for the relevant period, within that programme’s eligible scope. Units outside the eligible scope cannot be used, whatever their price.
Vintage and compliance period. Eligible units for the first phase generally come from reductions between 1 January 2021 and 31 December 2026. Vintage windows narrow the pool of usable units and can affect availability.
Host-country authorisation and corresponding adjustment. Where the framework requires it, the host country must authorise the unit and apply a corresponding adjustment so the tonne is not counted twice. Units with this authorisation are often scarcer, and this can influence price.
Supply, demand and timing. One analysis reported about 36.6–41 million eligible units issued and labelled as of 9 October 2026, against demand estimates ranging from 100–150 million tonnes (ICAO range via EDF) to 200–250 million units (IATA). A gap like this can put upward pressure on prices, though it does not guarantee any specific outcome. Airlines must cancel units for the 2024–2026 period by 31 January 2028. greenfueljournalsylvera
Project characteristics. Methodology, documentation quality, project type and perceived integrity all shape what buyers will pay.
Transaction costs. Brokerage, supplier fees, registry charges, retirement costs and delivery terms add to the headline price.
Deal structure. Contract size, payment terms and settlement arrangements, such as spot versus forward delivery, can change the effective price.
No single characteristic guarantees a higher price or confirms CORSIA eligibility. Always verify eligibility separately.
How Much Does CORSIA Compliance Cost for Airlines?
Airlines can estimate cost with a simple formula:
Estimated procurement cost = required eligible emissions units × price per unit + applicable transaction and service fees
The number of units must be determined under the applicable CORSIA rules. These cover the operator’s verified emissions on covered international routes, the sectoral growth factor, any operator-specific provisions, and the compliance period. Eligible fuels may also reduce the requirement where applicable.
Keep three figures separate: the number of units needed, the price per unit, and the total procurement budget. Each has its own uncertainty.
An Illustrative Example
The numbers below are hypothetical. They do not represent a real airline obligation or a market quote.
Suppose an operator calculates a first-phase requirement of 100,000 units. At an illustrative $15 per unit, with $30,000 in transaction and service fees, the estimated cost is (100,000 × $15) + $30,000 = $1,530,000.
If the unit price were $25 instead, the total would be $2,530,000. The units needed stay the same, but the budget changes substantially. Actual obligations and costs depend on verified emissions data, eligibility and procurement arrangements.
How to Compare CORSIA Carbon Credit Prices and Choose Eligible Units
A lower quote is not always the better offer. Compare offers on a like-for-like basis using this checklist:
- Programme and unit category: Confirm the unit’s programme is ICAO-approved and its scope is eligible.
- Vintage and period: Check that vintage and crediting dates fit the compliance period.
- Registry documentation: Ask for registry records and unit identifiers (serial numbers).
- Authorisation: Verify host-country authorisation and corresponding adjustment evidence where required.
- Availability and delivery: Confirm the supplier holds the units, who owns them, and when and how they transfer.
- Fees: Ask whether the price includes brokerage, registry, retirement or other charges.
- Documentation capacity: Check that the supplier can supply what your verifier will need.
- Offer type: Establish whether it is a firm quote, an indicative price or a conditional proposal.
The lowest advertised price may exclude fees, depend on authorisation that has not been issued yet, or cover units that do not fit your needs. Total procurement cost and compliance suitability matter more than the headline figure. No marketplace listing should be assumed CORSIA-eligible until you have checked it against ICAO’s current documents.
Where to Source CORSIA Carbon Credits and How CORSIA Carbon Credit Can Help
Buyers can explore eligible units through project developers, brokers, market platforms, exchange-traded contracts and programme registries. Exchange products exist too: ICE lists CORSIA Eligible Emissions Units (2024–2026) futures, quoted in US dollars per tonne, with one lot covering 1,000 units. Whatever the channel, confirm eligibility and documentation before you commit.
How CORSIA Carbon Credit Can Help
CORSIA Carbon Credit is a marketplace and advisory desk run from Indore. Its CORSIA services include offsetting requirement calculation, eligible unit sourcing and pre-purchase due diligence, registry transfer and cancellation, and support with emissions monitoring plans and annual reports. Its carbon credit marketplace lists projects with registry, vintage and project-type details, and the site states that listings remain subject to confirmation of availability, eligibility and registry status.
Not every listed credit is CORSIA-eligible, and a purchase does not by itself guarantee compliance. The CORSIA-eligible units checklist is a useful starting point, and the guide on how carbon credit prices are quoted explains how to read a quote. Request current pricing and confirm the specific units, eligibility, availability and transaction terms before making any procurement decision.

Frequently Asked Questions
1. How much do CORSIA carbon credits cost?
There is no single price. On 16 October 2026, one market assessment for Phase 1 units for December 2026 delivery stood at $13.15 per tCO₂e, while ICAO’s analysis estimated averages between $10 and $40 per tCO₂ for the first phase. Actual prices depend on the specific units, so request current quotes.
2. Why do CORSIA-eligible carbon credit prices vary?
Prices reflect programme, vintage, host-country authorisation, project type, supply and demand, and transaction terms. Fees and delivery arrangements also change the final cost.
3. Are CORSIA carbon credits more expensive than voluntary carbon credits?
Often they can be, because eligible units must meet extra requirements, including authorisation where applicable. That does not hold for every comparison, so compare similar project types and vintages using dated quotes.
4. How can airlines estimate their CORSIA offsetting costs?
First determine the unit requirement under CORSIA rules using verified emissions data. Then multiply by a current price per unit and add transaction and service fees.
5. How can buyers verify that carbon credits are eligible for CORSIA?
Check the unit against ICAO’s current Eligible Emissions Units document for programme, scope and vintage. Then confirm registry records, serial numbers and host-country authorisation evidence where required.
