As aviation decarbonization accelerates, alignment between CORSIA and Article 6 will determine who leads.

The Climate Action Center of Excellence (CACE) and HFW present a briefing that maps how CORSIA’s offsetting framework interacts with Article 6 cooperative approaches—clarifying when units qualify and what’s needed to avoid double counting while keeping investment flowing beyond 2030.

With Phase I (2024–2026) underway and Phase II (2027–2035) approaching, countries and airlines face a core challenge: securing host-country authorization and corresponding adjustments, and bridging timing gaps with NDC cycles.

What’s Inside

• A clear explanation of how CORSIA-eligible emissions units (EEUs) relate to ITMOs under Article 6.2, and the role of authorization and corresponding adjustments.
• Market context on expected demand growth and emerging governance signals shaping supply integrity.
• Risks from misaligned timelines between CORSIA Phase II (2027–2035) and many NDC implementation periods (to 2030), and why this matters for project finance.
• Practical mitigations: 2025 NDC updates covering 2030–2035, contract safeguards (authorization, corresponding adjustments, remedies), and options for future phase alignment.

The briefing helps host governments, airline operators, standards, and buyers navigate compliance, reduce double-counting risk, and maintain investor confidence as the aviation sector scales credible climate action.
