Aviation ETS Verification Services

The 3 major verification-phases

Achieving compliance for airline operators is a repetitive process during the monitoring year and in the beginning of the following year. This is why the verification process is broken down into 3 major phases:

1. Preparation
2. Execution
3. Completion

These 3 verification phases are broken down into the individual activities of the verification methodology.

Why does verification need to have such a firmly structured approach?

The reason is, that as a prerequisite to validate the reported data - the verifier has to understand each activity undertaken by the installation or aircraft operator including,

• the emission sources,

• the aircraft operator’s relevant aviation activities,

• the metering equipment used to monitor or measure activity data,

• the origin and application of emission factors and oxidation/conversion factors,

• any other data used to calculate or measure the emissions,

• and the environment in which the airline operates

• this includes a formal description of the various data sources,

• as well as a description of responsibilities, control procedures and uncertainty assessments.
