CORSIA compliance cost intelligence

Benchmarks, eligibility signals, and CORSIA outlooks

Quantifying CORSIA compliance costs

CORSIA compliance costs are shaped by more than emissions volume alone. Offset eligibility rules, issuance timelines, and host-country authorisations under Article 6 are constraining supply and introducing material pricing and timing risk across CORSIA phases.

As obligations scale through 2035, airlines face increasing exposure to compliance cost volatility, with direct implications for route economics, budgeting discipline, and long-term contracting.

Airlines and aviation stakeholders therefore need forward-looking signals on how policy decisions, registry developments, and market liquidity translate into real compliance costs, not just regulatory intent.

This brochure provides a clear, structured introduction to the data and intelligence Fastmarkets uses to quantify CORSIA compliance cost exposure. It moves beyond policy headlines to practical cost signals aligned with how airlines plan, price, and procure compliance.

Inside the brochure:

CORSIA Phase 1 spot benchmarks and methodology

Eligibility tracking across programs and vintages

Supply signals linked to Article 6 authorization status

How airlines use pricing intelligence to plan compliance costs

Eligibility, issuance, and authorization risks affecting procurement timing

The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) market has continued to digest the collapse of cookstove project developer Koko Networks at the end of January following the Kenyan government’s refusal to grant the project a letter of authorization (LoA) and the implications of this for supply going forward.

The International Civil Aviation Organization (ICAO), the governing body for Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), invited emissions unit programs to apply for its Technical Advisory Body (TAB) 2026 assessment cycle from February 9 to March 9. During this assessment cycle, the TAB will make a recommendation on a program’s eligibility under the first part of CORSIA’s second (mandatory) phase, which will run for the 2027-2029 compliance period.

CORSIA Phase 1 (CP1) spot prices extended their losses this week as newly tagged supply from Verra-registered cookstove and water filtration projects entered the market, reinforcing a broader repricing that has gathered pace since late January.
