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 European Commission has proposed removing additional CORSIA Phase 1 credit quality criteria for EEA aircraft operators ahead of an autumn vote, while acknowledging the change would allow use of credits it considers lower in environmental integrity. CORSIA Phase 1 spot credits rose to $11.60 per tCO2e following the announcement.
Indonesia has approved four forestry projects to issue carbon credits for the first time since its 2022 export moratorium, as the government launches a new national forestry carbon hub.
Japan Airlines expects carbon credits to play a growing role in helping it to meet its decarbonization targets as long as sustainable aviation fuel (SAF) remains constrained by limited supply and high costs, according to its vice president of sustainability and ESG promotion, Hideki Ochiai.
With CP1 spot prices down to $9.50 and airlines still holding back, the real debate is about which layer of CORSIA credit supply the market is pricing, from theoretical potential to the credits airlines can actually buy.
