From Fuel Data to Verified Report: Building a CORSIA MRV Workflow
Monitoring, reporting and verification under CORSIA is an operating-control process rather than a sustainability presentation. Airlines need a defensible chain from flight activity and fuel data through calculation, internal review, inde...

The Airline CORSIA Compliance Calendar for 2026–2028
CORSIA compliance is easier to manage when annual emissions reporting, verification, State notifications, unit procurement and three-year cancellation obligations are placed on one calendar. The transition from the 2024–2026 first phase...

When an Airline Can Use the ICAO CORSIA CERT
ICAO's CO2 Estimation and Reporting Tool can support applicability checks, reporting and data-gap treatment, but it is not a universal substitute for fuel-use monitoring. Eligibility depends on the operator's emissions profile and the ru...

Selecting an Accredited Verification Body for CORSIA
CORSIA verification is not ordinary financial audit work. The verifier must have the required accreditation and a scope that covers the relevant CORSIA verification activity, while the airline still needs enough aviation and emissions ex...

Inside a CORSIA Emissions Monitoring Plan
The Emissions Monitoring Plan is the control document that tells the administering State how an operator will identify covered flights, monitor fuel, calculate CO2 and manage data quality. A weak plan creates recurring verification findi...

CORSIA Changes in 2027: Preparing for the Second Phase
The start of CORSIA's second phase in 2027 changes route coverage and procurement planning for many international operators. ICAO's current 2027 State-pair document lists 134 participating States, making route mapping and credit demand f...

Aeroplane Operator Attribution Under CORSIA
Every CORSIA operator has to be attributed to an administering State. ICAO's framework uses identifiers such as ICAO designator, Air Operator Certificate information or juridical registration, making corporate and AOC structure relevant...

How New Airline Entrants Move Into CORSIA
A new operator can face MRV requirements before it develops a material offsetting obligation. The practical issue is to establish attribution, monitoring systems and verified reporting while the airline is still building network, fleet a...

The 10,000-Tonne CORSIA Threshold for Aircraft Operators
CORSIA MRV generally applies to an aeroplane operator producing more than 10,000 tonnes of CO2 annually from qualifying international flights using aeroplanes above the applicable weight threshold. Operators near the boundary should trea...

Closing the Loop With a CORSIA Emissions Unit Cancellation Report
Purchasing a carbon credit does not satisfy a CORSIA obligation by itself. Eligible units must be cancelled for the correct compliance purpose, the cancellation evidence must be compiled, and the operator's Emissions Unit Cancellation Re...
