Validation & Verification Services
CORSIA Monitoring
Plan Validation
A CORSIA Monitoring Plan defines how an aircraft operator collects, calculates, and reports fuel consumption and emissions data.
We review Monitoring Plans to confirm that methodologies, procedures, and reporting controls meet ICAO CORSIA requirements.
Our validation activities include reviewing:
✓ Fuel monitoring approaches
✓ Flight activity data collection
✓ Emissions calculation methodologies
✓ Data management and reporting procedures
CORSIA Emissions
Report Verification
Aircraft operators must submit annual emissions reports supported by independent verification.
We verify emissions data and supporting documentation to confirm accuracy, consistency, and compliance with ICAO requirements.
Our verification services include:
✓ Review of CO₂ emissions calculations
✓ Assessment of fuel consumption data
✓ Evaluation of calculation methodologies
✓ Review of eligible carbon offset claims

CORSIA Validation and Verification Services
What is CORSIA?
The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is ICAO’s global framework to address the growth of international aviation CO₂ emissions.
CORSIA establishes a standardized Monitoring, Reporting, and Verification (MRV) process for measuring, reporting, and independently verifying emissions from eligible international flights.
Aircraft operators participating in CORSIA must:
-
Monitor and report annual CO₂ emissions through ICAO’s MRV system
-
Submit emissions reports verified by an approved third party
-
Meet applicable offsetting requirements
Independent validation and verification provide assurance that emissions data, calculation methods, and offset claims meet ICAO requirements.
