Resource Description

This resource examines how CORSIA, the aviation offsetting scheme, aligns with Article 6.2 of the Paris Agreement. It highlights overlaps, gaps, and risks for carbon markets and national commitments.

Why This Matters

Better alignment of CORSIA and Article 6 will safeguard market integrity, sustain investment, and ensure aviation’s climate commitments support Paris goals.

Key Insights

Article 62 enables ITMOs; CORSIA uses eligible units (EEUs), which only partly overlap
Demand could reach 100 Mt CO2 annually under CORSIA and US$100b in Article 6 markets by 2030
Misalignment between CORSIA Phase II (2027–2035) and NDC cycles ending 2030 risks offset authorization and investor confidence
Solutions include revising NDCs to 2035+, contractual safeguards, and aligning future CORSIA phases with NDC periods
Strong ICAO–country–market cooperation is needed to ensure integrity and avoid double counting
