COMPLIANCE MARKETS · AVIATION
CORSIA compliance for airlines and corporate buyers
The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is now in its First Phase (2024–2026). Airlines on covered routes must offset emissions above their baseline by purchasing and cancelling CORSIA Eligible Emissions Units (EEUs) — with Phase 1 surrender due by 31 January 2028.
EWE provides spot and forward access to verified EEUs, LoA-confirmed supply, and full compliance advisory.
130 states participating
Baseline: 85% of 2019 emissions
SGF 2024: 15.4%
Phase 1 surrender: 31 Jan 2028
Phase 2 mandatory: 2027–2035
Phase 1 live: 2024–2026
LoA bottleneck — act now. As of April 2026, only 10 countries have issued Letters of Authorization (LoA) for CORSIA EEUs.
A credit can be fully issued by Verra or Gold Standard and still not be CORSIA-eligible until its host country grants an LoA. IATA estimates Phase 1 demand of 170–236 million EEUs at a cost of $4–5 billion. Supply with confirmed LoA is scarce. EWE has confirmed LoA supply from Guyana (ART TREES) and Madagascar (Verra) — available spot, delivery before the 31 Jan 2028 cancellation deadline.

CORSIA IMPLEMENTATION TIMELINE
Emissions monitoring begins
1 Jan 2019
All airlines with >10,000 tCO₂ international emissions required to monitor and report annually.
Pilot Phase
2021–2023
Voluntary participation. 85 states. Baseline: 2019 emissions only (COVID adjustment). EEU cancellation deadline was 31 Jan 2025.
Phase 1 — First Phase
2024–2026 · LIVE NOW
126+ states participating voluntarily. Baseline: 85% of 2019 emissions. SGF 2024 = 15.4% (OR: 55.6 Mt CO₂). Airlines notified of 2024 obligations by Nov 2025. States notify Phase 1 total by 30 Nov 2027.
Phase 1 EEU cancellation deadline
31 Jan 2028
Airlines must purchase and cancel sufficient EEUs to cover 2024–2026 offsetting requirements. Minimum threshold: 3,000 tCO₂ per 3-year period.
Phase 2 — Mandatory for all ICAO states
2027–2035
All ICAO contracting states mandatory (excl. LDCs, SIDS, LLDCs, and states with <0.5% RTK). Demand projected to reach ~2 billion EEUs through 2035. China, Russia, India, Brazil expected to join.
CORSIA scheme end
2027–2035
Full scheme concludes. From 2033, 15% of growth factor tied to individual airline performance (not sector average). Net zero aviation target: 2050.
