(2) The Planning Appeals Commission must—  (a) determine the process for determining the appeal; and  (b) when doing so, take into account any requests by either party to the appeal.  EXPLANATORY NOTE  (This note is not part of the Order)  This Order implements the monitoring, reporting and verification requirements of the Carbon  Offsetting and Reduction Scheme for International Civil Aviation (CORSIA) in Volume IV of  Annex 16 to the Convention on Civil Aviation adopted by the Council of the International Civil  Aviation Organisation on 27 June 2018.  This Order extend to the whole of the United Kingdom.  Under CORSIA a baseline level of carbon dioxide (CO$_{2}$) emissions is established for aeroplane  operators undertaking international flights. Aeroplane operators must monitor and report  emissions for each year.  Part 1 sets out the general provisions for the Order, including the scope of application and flights  to which the Order does not apply, and the definitions of various expressions used in the Order,  and specifically the definition for the “aeroplane operator”.  Part 2, in conjunction with Schedules 1 and 5, sets out the administrative provisions for the Order.  Chapter 1 sets out the requirements to notify ICAO of the United Kingdom’s voluntary  participation in CORSIA, to establish the attribution of aeroplane operators to the United  Kingdom and international flights to those aeroplane operators, defines the regulator and the  regulator’s tasks, sets out the record keeping requirements, compliance deadlines, and regulates  the use of equivalent procedures, and the role of the Civil Aviation Authority. Chapter 2 makes  provision in respect of an aeroplane operator’s change in circumstances. Chapter 3 sets out the  requirements for the submission of applications and notices under the Order to a regulator, the  determination of applications by a regulator, and the service of notices given by a regulator.  Part 3, in conjunction with Schedules 1 to 6, establishes the monitoring, reporting and verification  (MRV) requirements of an aeroplane operator’s annual CO$_{2}$ emissions from attributable flights.  Chapter 1 sets out the applicability of the MRV requirements. Chapter 2 establishes the  requirements for the monitoring of aeroplane operator annual CO$_{2}$ emissions. These provisions  include the duty on an aeroplane operator to monitor its CO$_{2}$ emissions, the monitoring methods  available, the requirement for an Emissions Monitoring Plan, the calculation of CO$_{2}$ emissions  from aeroplane fuel use, and the monitoring of CORSIA eligible fuels. Chapter 3 establishes the  requirements for the reporting of aeroplane operator annual CO$_{2}$ emissions. These provisions  include the requirements on the aeroplane operator to report CO$_{2}$ emissions and CORSIA eligible  fuel use, and on the Secretary of State to report those emissions for aeroplane operators  administered in the United Kingdom to ICAO. Chapter 4, in conjunction with Schedule 6, sets out  the standards and requirements for the verification and accreditation bodies and establishes the  requirements for the verification of aeroplane operator annual CO$_{2}$ emissions and CORSIA  eligible fuel use. Chapter 5 sets out the requirement for data management and control. These  provisions include the requirements for the management of data gaps, corrective actions,  improvements to the monitoring methodology, the rounding of data, and the use of an electronic  data exchange and automated systems.  Part 4 makes provision for a regulator to charge for services undertaken pursuant to the Order,  subject to the approval of the charge scheme by the relevant minister, its publication, and any  revision of the charges.  70
