Paragraph 4 Methods and means of calculating emissions from international flightsI1

an estimate of CO₂ emissions for all international flights for 2019^f1 with supporting information on how the estimation was calculated, and

the type of input method used in the CERT, namely—

the Fuel Use Monitoring Method used, namely—

if different Fuel Use Monitoring Methods are to be used for different aeroplane types, the aeroplane operator must specify which method applies to which aeroplane type,

information on the procedures for determining and recording fuel density values, whether standard or actual, as used for operational and safety reasons, and a reference to the relevant aeroplane operator documentation, and

the systems and procedures to monitor fuel consumption in both owned and leased aeroplanes. If the aeroplane operator has chosen the Fuel Allocation with Block Hour method, information must be provided on the systems and procedures used to establish the average fuel burn ratios as described in Schedule 2.

an estimate of CO₂ emissions for all international flights F4which are subject to offsetting requirements under article 41A for the year before the emissions monitoring is to occur, such as an estimate of such emissions for 2020 for monitoring in 2021, as well as information on how the fuel use and CO₂ estimation was calculated, and

the type of input method used in the CERT, namely—

the Fuel Use Monitoring Method used, namely—

if different Fuel Use Monitoring Methods are to be used for different aeroplane types, the aeroplane operator must specify which method applies to which aeroplane type;

information on the procedures for determining and recording fuel density values, whether standard or actual, as used for operational and safety reasons and a reference to the relevant aeroplane operator documentation;

the systems and procedures to monitor fuel consumption in both owned and leased aeroplanes; and

if the aeroplane operator has chosen the Fuel Allocation with Block Hour method, information must be provided on the systems and procedures used to establish the average fuel burn ratios as described in Schedule 2.
