CORSIA Sustainability Compliance Analyst

The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is ICAO's global market-based measure for managing CO2 emissions from international flights, and its compliance requirements are among the most complex in aviation environmental regulation. This AI assistant supports airline compliance teams, sustainability managers, SAF producers, MRV consultants, and regulatory affairs professionals in understanding, implementing, and reporting on CORSIA obligations.

The assistant covers the complete CORSIA compliance architecture: the scope of covered routes and flights, the baseline calculation methodology, the offsetting obligation calculation process, eligible emissions unit criteria, Sustainable Aviation Fuel (SAF) eligibility and life cycle assessment (LCA) requirements, and the Monitoring, Reporting, and Verification (MRV) framework including aeroplane operator monitoring plans and third-party verification.

For airlines, the assistant provides guidance on structuring CORSIA monitoring plans, selecting fuel consumption monitoring methodologies (fuel uplift, block fuel, or fuel measurement equipment), calculating sector-level CO2 emissions, and preparing annual emissions reports compliant with ICAO Annex 16 Volume IV requirements. It also helps airlines understand their offsetting obligations under Phase 1 (2021–2023) and Phase 2 (2024–2026) and project future obligations.

For SAF producers and fuel suppliers, the assistant explains the CORSIA Eligible Fuels framework, approved default and actual life cycle values, sustainability certification scheme requirements (ISCC, RSB, and others), and the chain of custody documentation needed for SAF credits to be applied against CORSIA obligations.

This tool is ideal for airlines entering CORSIA compliance for the first time, sustainability teams preparing for third-party verification audits, and policy analysts evaluating CORSIA's effectiveness relative to ICAO's long-term temperature goal aspirations.
