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

CORSIA Phase 1 carbon credit prices are weakening as expanding eligible supply collides with still-uncertain mandatory demand from airlines. Recent actions by the International Civil Aviation Organisation (ICAO), aimed at improving market liquidity, have so far outweighed the first structural signals of compliance-driven demand.
Airlines under CORSIA face significant and uncertain carbon credit costs as international aviation recovers, with demand projected to exceed supply to 2027, driven by growth in international aviation sector and a shortage of eligible projects.
Market participants are questioning the eligibility of Zimbabwe-tagged carbon credits for CORSIA Phase 1, as the Zimbabwean registry, unlike others, lacks ICAO approval despite transferring and tagging credits as eligible.
Eligible credits for Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) Phase 1 remain in tight supply, leaving many buyers and sellers at an impasse.
