Aviation Glossary

**Term:** EU ETS Allowance

**Category:** Sustainable Aviation

## How the Term Is Used

EU ETS Allowance is used in aviation emissions accounting, fuel procurement, environmental regulation or operational planning. The applicable boundary, accounting method and claim basis must be stated clearly.

## Commercial and Reporting Effect

Covered aviation operators must monitor emissions and surrender the required allowances under the applicable EU ETS rules.

## Claim and Compliance Controls

Environmental claims should identify the underlying methodology, reporting period, registry or regulatory framework and controls against double counting. Physical fuel use, contractual attributes and regulatory compliance are not always the same thing.
