Field 1 – Instrument identification code should be reported with ISIN EU000A2QMW50 for EU allowances and EU000A2QMW68 for EU aviation allowances. In case of derivatives having as underlying a phase 4 emission allowance, Field 26 – Underlying instrument code should be populated with EU000A2QMW50 for EU allowances and EU000A2QMW68 for EU aviation allowances. The table below clarifies the different reporting scenarios based on the type of emission allowance. The fields displayed in the tables are all RTS 23 fields that are applicable to emission allowances or derivatives thereof in the FIRDS CFI validation rules.
