Regulation 15
of Air Navigation (Carbon Emissions and Reporting) Regulations 2022
Regulation 15
Monitoring of fuel use by primary registered Singapore operators
Subregulation 1
Subject to paragraph (3), a primary registered Singapore operator must monitor and record its fuel use from the operation, during each reporting period, of any defined aeroplane for any defined international flight attributable to the primary registered Singapore operator, the monitoring and recording for which must be in accordance with the applicable monitoring method specified in its approved emissions monitoring plan.
Subregulation 2
A primary registered Singapore operator without an approved emissions monitoring plan before the start of a reporting period may first monitor and record its fuel use from the operation, during the reporting period, of any defined aeroplane for any defined international flight attributable to the primary registered Singapore operator, in the following manner until it obtains the approval of the Director‑General of Civil Authority under regulation 13(4) for its emissions monitoring plan:
if the primary registered Singapore operator has submitted an emissions monitoring plan under that regulation (called in this sub‑paragraph a draft emissions monitoring plan) but has not obtained an approved emissions monitoring plan — in accordance with the applicable monitoring method specified in the draft emissions monitoring plan;
if the primary registered Singapore operator has not submitted an emissions monitoring plan under that regulation — in accordance with an applicable monitoring method that the primary registered Singapore operator has chosen.
Subregulation 3
For the purposes of paragraph (1), unless the Director‑General of Civil Aviation otherwise requires, the applicable monitoring method is —
for a primary registered Singapore operator whose total CO2 emissions produced from the operation, in a reporting period, of any defined aeroplane for any defined international flight attributable to the primary registered Singapore operator, is 50,000 tonnes or more — 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; or
for a primary registered Singapore operator whose total CO2 emissions produced from the operation, in a reporting period, of any defined aeroplane for a defined international flight attributable to the primary registered Singapore operator is less than 50,000 tonnes — either of the following monitoring methods:
a fuel use monitoring method specified in Part 1 of the Aviation Specifications 4 — Fuel Use Monitoring Methods;
the ICAO CORSIA CERT specified in Part 2 of the Aviation Specifications 4 — Fuel Use Monitoring Methods.
Subregulation 4
Despite paragraph (3)(a), if the total CO2 emissions of the primary registered Singapore operator mentioned in that paragraph decreases below 50,000 tonnes for each of 2 consecutive years, the primary registered Singapore operator —
may use the ICAO CORSIA CERT to monitor and record its fuel use from the operation, during the second reporting period immediately following (called in this paragraph the relevant year), of any defined aeroplane for any defined international flight attributable to the primary registered Singapore operator; but(b)must submit a revised emissions monitoring plan no later than 30 September in the year immediately before the relevant year if the Singapore operator does so.
Subregulation 5
Despite paragraph (3)(b), if the total CO2 emissions of the primary registered Singapore operator mentioned in that paragraph increases to 50,000 tonnes or more in each of 2 consecutive years, and the primary registered Singapore operator has been monitoring its fuel use from the operation, during those years, of any defined aeroplane for any defined international flight attributable to the primary registered Singapore operator, using the ICAO CORSIA CERT, the primary registered Singapore operator must —
submit a revised emissions monitoring plan no later than 30 September in the year immediately following (called in this paragraph the relevant year) specifying the use of 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; and
use that fuel use monitoring method to monitor and record its fuel use from the operation, during the reporting period immediately following the relevant year, of any defined aeroplane for any defined international flight attributable to the primary registered Singapore operator.
