how abatable helps
Move from obligation to action
Airlines that move early on CORSIA stand to benefit most. Abatable combines procurement, advisory, and intelligence so you can get ahead of your obligations, secure eligible supply, and shape a clear CORSIA strategy with our dedicated team.
Procure CORSIA-eligible credits
We run a competitive, market-wide process to source CORSIA eligible credits on your behalf, bringing sourcing, evaluation, and contracting into a single platform covering 5,000 carbon project developers and a proprietary dataset of more than 18,000 carbon projects. We structure portfolios with contract guarantees that safeguard delivery.
The Abatable edge: We've already closed CORSIA transactions for airlines pursuing First Phase compliance, helping them meet requirements in the most cost- and risk-effective way.
Develop your CORSIA strategy
Abatable works directly with your in-house team, applying deep CORSIA and Article 6 expertise to your compliance strategy. From country-specific policy analysis to credit structuring and financing, our advisors draw on policy, legal, and market experience across the carbon and aviation landscape to deliver relevant, timely advice.
The Abatable edge: Our team includes some of the most experienced CORSIA and Article 6 practitioners in the market, including a member of CORSIA's Technical Advisory Body with over 20 years experience on the subject, so your strategy is always grounded in genuine technical depth.

CORSIA eligibility is determined at two levels. We assess both.
A credit only counts towards CORSIA if both the project and its host country meet the scheme's requirements. Our funnel approach to CORSIA due diligence screens each eligibility criterion separately, so you can prioritise the projects most likely to qualify and see exactly where the risk sits.
Project level – is the credit itself eligible, and will it deliver?
We check each project against the current ICAO-approved list of programmes and the eligibility criteria that sit beneath it: the standard, methodology, vintage, and crediting period. We then confirm the host country government's Letter of Authorisation and what it actually authorises, the guarantee behind it, and we weigh the project developer’s track record and delivery risk before anything reaches your shortlist.
Country level – will the host country stand behind the credit?
A project can be sound and still carry country risk. Through our Article 6 Readiness Risk Matrix, we profile the host country's Article 6 framework, its Designated National Authority, its record on issuing and revoking Letters of Authorisation, the status of its Article 6.2 reporting, and its wider cooperative-approach and crediting experience. Country readiness is also a crucial factor in our identification of future supply opportunities.
Built for CORSIA's biggest challenges. Designed around you.
Our CORSIA solutions are built around the realities airlines face in a compliance market that’s still taking shape. Our platform and team flex to your specific needs.
Market challenges
CORSIA eligibility is a moving target. The approved list of programmes and the rules beneath it evolve, meaning it’s important to stay on top of the scheme’s rules.
We assess every credit against the current ICAO-approved list and the criteria beneath it, along with additional risk indicators, and we structure deals with protection built in if a project's eligibility status changes.
A government Letter of Authorisation – to allow a project to be used for CORSIA – can be revoked. The host country, not the project, ultimately stands behind a credit's eligibility.
We profile host-country Article 6 readiness and revocation history through our Article 6 Readiness Risk Matrix, so you can see country-level risk before you commit.
Pricing can be opaque, and a CORSIA premium is emerging. It’s hard to know whether an offer is fair.
Our platform collects competing offers for the same projects and benchmarks them transparently, enabling us to negotiate on your behalf to lower prices.
Many airlines have no in-house carbon desk. CORSIA lands on teams already stretched across operations and sustainability.
Our advisors act as an extension of your team, providing support from country policy analysis through to assembling and contracting the portfolio.
Eligible does not mean high quality. A compliant credit can still carry reputational and delivery risk.
We conduct independent, tiered due diligence at both a project and country level, we assess projects against our five-pillar risk framework, and we continue to monitor projects over time. We can provide the right level of due diligence to match your needs.
Supply and demand are hard to predict during CORSIA’s First and Second Phases, making it difficult to plan a multi-year strategy without a view of how the market evolves.
Our intelligence platform provides supply forecasts, airline-specific demand projections, and country policy profiles, with consultation calls included so you can go deeper with our team.
Lock in eligible supply, navigate evolving rules, and position ahead of a market still forming.
Available CORSIA credits remain limited due to current scheme bottlenecks, while airline obligations are set to grow each year. Airlines that plan early secure better prices and more choice.

Customer story
How we de-risked and delivered a major airline's first CORSIA transaction
One of Asia's leading airlines needed to source CORSIA-eligible credits against strict internal procurement criteria, at a point when limited fully eligible supply existed.
Step 1
We evaluated 152 projects across four countries using our Article 6 readiness risk matrix, ranking each on country policy risk, methodology alignment with ICAO standards, delivery feasibility, and insurance availability.
Step 2
We shortlisted five high-potential projects across Cambodia, Vietnam, Kenya, and Ghana, and structured the deal with a protective clause allowing reversal if a project failed to secure CORSIA eligibility within a year.
Step 3
Abatable then assembled project offers and delivered a single project for 100,000 tonnes with full delivery guarantee, backed by a portfolio of replacement credits to manage supply risk.

Frequently asked questions
When do First Phase obligations need to be met?
The First Phase credit retirement deadline is January 2028. Because eligible supply is limited and obligations grow each year, airlines that plan early can secure better prices and more choice.
What is Abatable's track record in CORSIA?
Abatable has supported some of the first CORSIA transactions in the market, including with a major Asian airline. We are in active discussions with close to 50 airlines on how to meet their obligations, and our Director of Knowledge, Policy, and Advocacy sits on CORSIA's Technical Advisory Body. This CORSIA work builds on the wider Abatable platform: founded in 2021, we have facilitated over 55mn tonnes of carbon credit transactions and supported more than 200 organisations, drawing on a network of over 5,000 project developers and a dataset of more than 18,000 carbon projects.
Why use a procurement partner for CORSIA rather than buying direct?
CORSIA is operationally complex. Eligible supply is scarce, authorisation and guarantees have to be verified, and risk sits at both a project and country level. A dedicated partner manages that complexity end-to-end: access to the wider supply landscape, independent due diligence at project and country level, transparent benchmarking, and deal structures that protect you if a project's eligibility status changes. That depth is difficult to achieve alone or through separate brokers.
What is a Letter of Authorisation, and why does it matter?
A Letter of Authorisation is the host country's confirmation that a credit can be used for international mitigation purposes, including CORSIA. It is what allows a credit to count towards compliance. Because a country can revoke an authorisation, Abatable assesses both the authorisation itself and the host country's track record in revocations and Article 6 – which CORSIA is tied to – before recommending any credit.
Which carbon credits are eligible under CORSIA?
A credit is eligible only if it comes from a programme on the current ICAO-approved list, meets the criteria beneath it on standard, methodology, vintage, and crediting period, and is backed by an authorisation for CORSIA use from its host country – known as a Letter of Authorisation. For First Phase compliance, that authorisation must be supported by a Corresponding Adjustment – i.e. the credit is accounted for in national inventories – or an approved guarantee. As eligible programmes evolve, Abatable assesses every credit against the scheme’s live requirements rather than a fixed list.
