SECOND SCHEDULERegulations 13(3) and 14(2)Content of emissions monitoring planPart 1Primary registered Singapore operator identification
1. An emissions monitoring plan must contain the following identification information of the primary registered Singapore operator:
name and address of the primary registered Singapore operator;
information for attributing the primary registered Singapore operator to Singapore, including —
information on the ICAO Designator used for air traffic control purposes, as listed in ICA Designators for Aircraft Operating Agencies, Aeronautical Authorities and Services (Doc 8585); and
if the primary registered Singapore operator does not have an ICAO Designator, a copy of its air operator certificate;
details of ownership structure relative to any other primary registered Singapore operators with international flights, including whether the primary registered Singapore operator —
is a parent company to any other primary registered Singapore operators with international flights; or
is a subsidiary of any other primary registered Singapore operators with international flights;
if the primary registered Singapore operator in a parent‑subsidiary relationship seeks to be considered as a single primary registered Singapore operator for the purposes of these Regulations, confirmation that the parent and subsidiary (or subsidiaries) are attributed to Singapore, and that the subsidiary (or subsidiaries) is (or are) wholly‑owned by the parent;
contact information for the person within the primary registered Singapore operator’s company who is responsible for the emissions monitoring plan;
the description of the primary registered Singapore operator’s activities, including —
scheduled or non-scheduled flights;
operations of aircrafts for general aviation operations; and
geographical scope of operations.Part 2Fleet and operations data
2. An emissions monitoring plan must contain the following information on the fleet and operations of the primary registered Singapore operator:
a list of aeroplane types, and type of fuel used in aeroplanes operated for international flights (e.g. Jet‑A, Jet‑A1, Jet‑B, AvGas), at the time of submission of the emissions monitoring plan, including —
the aeroplane types with a MCTOM of 5,700 kg or greater;
the number of aeroplanes per type, including owned and leased aeroplanes; and
the type of fuel used by the aeroplanes;
the information used for attributing international flights to the primary registered Singapore operator, including —
a list of the ICAO Designator (or Designators) used in Item 7 (aircraft identification) of the primary registered Singapore operator’s flight plans; and
if the primary registered Singapore operator does not have an ICAO Designator, a list of the nationality or common mark, and registration mark of aeroplanes that are explicitly stated in the air operator certificate, complex general aviation certificate or aerial work certificate, and used in Item 7 (aircraft identification) of the primary registered Singapore operator’s flight plans;
the procedures on how changes in the aeroplane fleet and fuel used will be tracked to ensure completeness of monitoring;
the procedures on how the specific flights of an aeroplane will be tracked to ensure completeness of monitoring;
the procedures for determining which aeroplane flights are international flights, and are subject to these Regulations;
a list of States to where the primary registered Singapore operator operates international flights at the time of initial submission of the emissions monitoring plan;
the procedure for identifying international flights mentioned in regulation 4(2) that are not counted for the purposes of regulation 4(1).Part 3Methods and means of calculating emissions from international flights
3. If the primary registered Singapore operator is eligible to use ICAO CORSIA CERT as a fuel monitoring method under regulation 15(3)(b) or (4), and chooses to use ICAO CORSIA CERT as a fuel monitoring method for the purposes of regulation 15, the following information must be provided:
an estimate of CO2 emissions for all international flights for the reporting period immediately before the reporting period to which the enhanced emissions report relates, and information on how the fuel use and CO2 emissions during the firstmentioned reporting period was calculated;
the type of input method used in the method used in the ICAO CORSIA CERT, whether the Great Circle Distance input method described in Part 2 of the Aviation Specifications 4 — Fuel Use Monitoring Methods issued by the Director-General of Civil Aviation or the Block Time input method described in Part 2 of the Aviation Specifications 4 — Fuel Use Monitoring Methods.
4. If the primary registered Singapore operator uses a fuel use monitoring method specified by the Director‑General of Civil Aviation in the Aviation Specifications 4 — Fuel Use Monitoring Methods, the following information must be provided:
the particular fuel use monitoring methods that will be used (i.e. Method A, Method B, Block‑off / Block‑on, Fuel Uplift, or Fuel Allocation with Block Hour);
if different fuel use monitoring methods are to be used for different aeroplane types, which methods applies to which aeroplane types;
the information on the procedures for determining and recording fuel density values (standard or actual) as used for operational and safety reasons, and a reference to the technical log of the record of fuel density maintained by the primary registered Singapore operator mentioned in regulation 16(2);
the systems and procedures to monitor fuel consumption in both owned and leased aeroplanes;
if the primary registered Singapore operator has chosen the Fuel Allocation with Block Hour method described in Part 1 of the Aviation Specifications 4 — Fuel Use Monitoring Methods, the systems and procedures used to establish the average fuel burn ratios as described in Part 1 of the Aviation Specifications 4 — Fuel Use Monitoring Methods.Part 4Data management, data flow and control
5. An emissions monitoring plan must contain the following information relating to the primary registered Singapore operator’s data management:
the roles, responsibilities and procedures on data management;
the procedures to handle data gaps and erroneous data values, including —
secondary data reference sources that would be used as an alternative;
alternative method or methods to handle data gaps and erroneous data values in case the secondary data reference source is not available; and
if a primary registered Singapore operators uses a fuel use monitoring method specified by the Director‑General of Civil Aviation in Part 1 of the Aviation Specifications 4 — Fuel Use Monitoring Methods, information on systems and procedures for identifying data gaps and for accessing whether the 5% threshold for errors or omissions mentioned in regulation 12(3) has been reached;
the documentation and record keeping plan;
an assessment of the risks associated with the data management processes and means for addressing significant risks;
the procedures for making revisions to the emissions monitoring plan and resubmitting relevant portions to the Director‑General of Civil Aviation when there are material changes;
the procedures for providing notice in the enhanced emissions report of non‑material changes that require the attention of the Director‑General of Civil Aviation;
a data flow diagram summarising the systems used to record and store data associated with the monitoring and reporting of CO2 emissions.
