(2) A verification body must conduct the verification according to ISO 14064-3:2006, and the relevant requirements in paragraph 3 of Schedule 6. 

(3) Following the verification of the Emissions Report by the verification body, the aeroplane operator and the verification body must both independently submit, upon authorisation by the aeroplane operator, a copy of the Emissions Report and associated Verification Report to the Regulator, in accordance with the timeline set out in Schedule 1. 

(4) The Regulator must perform an order of magnitude check of the Emissions Report in accordance with the timeline set out in Schedule 1 to assess the completeness of the data provided in that report. 

(5) To facilitate order of magnitude checks and ensure the completeness of reported data, and where necessary to support the implementation of the requirements in this Order, the Regulator may agree to share with another State’s regulator, specific data and information contained in an aeroplane operator’s Emissions Report where that aeroplane operator performs flights to and from the State of the requesting regulator. 

(6) The Regulator must inform any relevant aeroplane operator about such a request for that information. 

(7) In the absence of an agreement between the two States, this information must not be disclosed to third parties. 

(8) A Regulator must provide the name of the verification body used to verify an Emissions Report on being asked for the disclosure of information by the regulator of another State. 

## Verification of sustainable aviation fuels 

36. —(1) Fuel purchases, transaction reports, fuel blending records and sustainability credentials must constitute the documentary proof for the purpose of verification and approval of emissions reductions from the use of CORSIA eligible fuels. 

(2) An aeroplane operator must ensure that it, or its designated representative, has audit rights over the production records for the CORSIA eligible fuels that it purchases( a ). 

## Data gaps 

## Data management and control 

## CHAPTER 5 

37. —(1) An aeroplane operator using a Fuel Use Monitoring Method, as described in Schedule 2, must fill data gaps using the CERT, as described in Schedule 3, provided that the data gaps during a compliance period do not exceed the following thresholds— 

(a) 2019-2020 period: 5 per cent of international flights; 

(b) 2021-2035 period: 5 per cent of international flights between State Pairs defined in the ICAO document entitled “CORSIA States for Chapter 3 State Pairs”( b ). 

(2) The aeroplane operator must correct issues identified with the data and information management system in a timely manner to mitigate ongoing data gaps and system weaknesses. 

(3) If the aeroplane operator realises it has data gaps and system weaknesses that exceed the threshold in paragraph (1), it must engage with the Regulator to take remedial action to address this.
