Platts to amend CEC methodology in line with ICAO regulations

Platts, part of S&P Global Commodity Insights, will amend its methodology for the Platts CORSIA Eligible Credit, or CEC, price assessment to incorporate all methodologies and standards that the International Civil Aviation Organization has approved, effective Jan. 31.

ICAO is the regulatory body governing the Carbon Offsetting and Reduction Scheme for International Aviation, or CORSIA. Platts will align its Platts CEC methodology with the latest regulatory changes that define CORSIA credits.

This includes any additional requirements to be met by the standards around a corresponding adjustment or insurance for credits.

A corresponding adjustment, or CA, guarantees the host country will not claim the credit against its own climate goals, known as Nationally Determined Contributions. This prevents the double-counting of credits and is essential for carbon trading between countries as outlined in Article 6 of the Paris Agreement.

In line with the latest ICAO guidance on insurance, Platts will no longer look at only a promise of CA for delivery but actual CA received wherever applicable. Additionally, standards may have to meet further criteria to deem credits eligible, such as assigning specific insurance providers, which Platts will also take into consideration, in line with ICAO regulations.

This means that the Platts CEC assessment will reflect only market data that aligns with the requirements for a credit to be CORSIA eligible in phase 1 (2024-2026) and in phase 2 (2027-2035).

Should market data and received heards not operationally reflect a carbon credit that is CORSIA-eligible, Platts will not consider this data for the assessment of Platts CEC.

Platts will continue to align its CEC methodology with ICAO on any changes or additions made to the eligible credits and standards.
