Climate Impact X (CIX) will today launch its standardised physical spot contract for CORSIA-eligible credits: CIX CORSIA Phase 1 X – Global Market (CIX CP1X-GM).

Trading under the contract code ‘CP1X-GM’ on CIX Exchange, the contract consolidates supply from all registries fully approved by the International Civil Aviation Organisation (ICAO) for the 2024-2026 compliance period (first phase), giving airlines and other market participants access to Eligible Emissions Units (EEU) under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).

To view the CP1X-GM spot contract instrument, see here. 

A new contract for the next phase of the CORSIA scheme will be created closer to 2027, reflecting the start year of the 2027-2035 compliance year (second phase).

In conjunction with the launch of the CIX CORSIA X contract, CIX has updated its Benchmark Methodology Guidebook with immediate effect to include the CIX CORSIA X Methodology Waterfall. The updated CIX Benchmark Methodology Guidebook is available here.

The CP1X-GM contract will help inform the CIX CORSIA Phase 1 X – Global Markets (CP00002) price benchmark, which tracks the spot traded value of the most competitive CORSIA Eligible Emissions Units for the 2025-2026 compliance period (first phase). 

The assessment is published in the CIX Carbon Daily pricing intelligence report, and through CIX paid data services.
 
CIX Exchange is open for trading Monday through Friday (excluding public holidays) from 9:00am to 7:00am (the following Trading Day) SGT.
