(3) If a Default Life Cycle Emissions value is used, the aeroplane operator must use the ICAO  document entitled “CORSIA Default Life Cycle Emissions Values for CORSIA Eligible Fuels”( a )  for the calculation in paragraph (1).  31. —(1) An aeroplane operator must submit to the Regulator a copy of its verified Emissions  Report for approval by the Regulator and a copy of the associated Verification Report in  accordance with the timeline set out in Schedule 1.  (2) The Regulator must decide on the level of aggregation, being State pair or aerodrome pair,  for which an aeroplane operator must report the number of international flights in accordance with  Field 7 in Table 1 in Schedule 5, and CO$_{2}$ emissions in accordance with Field 8 in that Table. The  Regulator must inform the aeroplane operator whether Fields 7 and 8 in the Emissions Report  must be reported at the level of State pair or aerodrome pair during the approval process for its  Emissions Monitoring Plan.  (3) An Emissions Report must contain the information set out in Table 1 of Schedule 5. An  aeroplane operator that uses the CERT is not required to report Field 5 in Table 1.  (4) When an aeroplane operator reports its consolidated CO$_{2}$ emissions from international flights  during the 2019-2020 period, including those of subsidiary aeroplane operators, disaggregated  data relating to each subsidiary aeroplane operator must be appended to the main Emissions  Report.  (5) In specific circumstances where an aeroplane operator operates a very limited number of  flights between State pairs, it may submit a written request to the Regulator that such data not be  published at the aeroplane operator level, as set out in Tables 4 and 5 of Schedule 5, explaining the  reasons why disclosure would harm its commercial interests.  (6) Based on this request, the Regulator must determine whether this data is confidential.  (7) In specific circumstances where aggregated State pair data may be attributed to an identified  aeroplane operator as a result of a very limited number of aeroplane operators conducting flights  on a State pair, that aeroplane operator may request in writing to the Regulator that such data not  be published at State pair level, explaining the reasons why disclosure would harm their  commercial interests.  (8) Based on this request, the Regulator must determine whether this data is confidential.  32. —(1) An aeroplane operator must subtract CORSIA eligible fuels traded or sold to a third  party from its total reported quantity of CORSIA eligible fuels.
