## Fleet and operations data 

3.  The following fleet and operations data is required— 

(a) list of the aeroplane types and type of fuel, such as Jet-A, Jet-A1, Jet-B, and AvGas, used in aeroplanes operated for international flights at the time of submission of the Emissions Monitoring Plan, recognising that there may be changes over time. The list must include— 

(i) aeroplane types with a maximum certificated take-off mass of 5,700 kg or greater and the number of aeroplanes per type, including owned and leased aeroplanes, and 

(ii) type of fuel used by the aeroplanes; 

(b) information used for attributing international flights to the aeroplane operator, being— 

(i) ICAO Designator used in Item 7 of the aeroplane operator’s flight plans, or 

(ii) a list of the nationality or common mark, and registration mark of aeroplanes that are explicitly stated in the air operator certificate, or equivalent, and used in Item 7 of the aeroplane operator’s flight plans if the aeroplane operator does not have an ICAO Designator; 

(c) procedures on how changes in the aeroplane fleet and fuel used will be tracked, and subsequently integrated in the Emissions Monitoring Plan; 

(d) procedures on how the specific flights of an aeroplane will be tracked to ensure completeness of monitoring; 

(e) procedures for determining which aeroplane flights meet the definition of international flights and are therefore subject to the requirements in Part 3 of this Order; 

(f) list of States to where the aeroplane operator operates international flights at the time of initial submission of the Emissions Monitoring Plan( a ); 

(g) procedures for determining which international aeroplane flights are subject to offsetting requirements under Part II, Chapter 3 of Annex 16, Volume IV to the Chicago Convention( b ); 

(h) procedures for identifying domestic flights and/or humanitarian, medical or firefighting international flights that would not be subject to the requirements in Part 3 of this Order. 

## Methods and means of calculating emissions from international flights 

4. —(1) The methods and means of calculating emissions from international flights during the periods specified in this paragraph are as follows. 

## Methods and means for establishing the average emissions during the 2019-2020 period 

(2) If the aeroplane operator uses the CERT as described in Schedule 3, the following information must be provided— 

(a) an estimate of CO$_{2}$ emissions for all international flights for 2019( c ) with supporting information on how the estimation was calculated, and 

(b) the type of input method used in the CERT, namely— 

(i) Great Circle Distance input method, or 

(ii) Block Time input method.
