CELEBI GROUND HANDLING 2025 AR

38 Çelebi Ground Handling 2025 Annual Report 7. Greenhouse Gas Inventory Calculations - Methodology Our Company conducts yearly greenhouse gas inventory calculations in accordance with the ISO 14064 standard. The station buildings, workshop, and vehicle/equipment parking zone utilized by Çelebi Ground Handling in the airport apron area, which falls under the financial and administrative control of Çelebi Ground Handling, along with the passenger services offices located in the airport terminal building and rented from the terminal operator, are encompassed in the greenhouse gas inventory as direct greenhouse gas emissions (Scope 1) and energy indirect greenhouse gas emissions (Scope 2). As of the 2021 inventory, our greenhouse gas inventory includes the emissions resulting from the activities of our personnel service providers, and the fuel consumption of our employees who receive business travel/fuel support as other indirect greenhouse gas emissions (Scope 3). The year 2011 is used as the base year in the calculations. The details of the methodology employed within the scope of the ISO 14064 standard are outlined as follows: - Emission factors within the scope of tier-1 (IPCC, IEA etc.) are used in our calculations. - The emission factors we have chosen on the basis of emission source are as follows: - Warm-Up= IPCC 2006, Vol.2, Table 2.4. Default emission factors for stationary combustion in the commercial/institutional category (kg of greenhouse gas per TJ on a net calorific basis) (page 2.20) - GPU, ASU, ACU, emergency generator, vehicle washing equipment= IPCC 2006, Vol.2, Table 2.4. Default emission factors for stationary combustion in the commercial/institutional category (kg of greenhouse gas per TJ on a net calorific basis) (page 2.20) - Refrigeration system leaks = IPCC 2006, Vol.3; Chapter 7, Table 7.9: Estimates for charge, lifetime and emission factors for refrigeration and air-conditioning systems (page 7.52) - Impact Potentials on Global Warming = IPCC Fifth Assessment Report, 2014 (AR5); GWP values for 100-year time horizon - Fuel intensity = Regulation on Increasing Efficiency in the Use of Energy Resources and Energy, Annex-2: Lower Calorific Values of Energy Resources and Conversion Coefficients to Petroleum Equivalent - On-road and off-road vehicles = Sources: IPCC 2006, Vol.2; - Table 3.2.1. Road transport default CO 2 emission factors and uncertainty ranges (page 3.16) - Table 3.2.2. Road transport N 2 O and CH 4 default emission factors and uncertainty ranges (page 3.21) - Table 3.3.1. Default emission factors for off-road mobile sources and machinery (page 3.36) 8. Environmental Reporting Our Company regularly reports its efforts and data pertaining to environmental sustainability to the Carbon Disclosure Project (CDP), which is comprised of investors who represent a total of USD 100 trillion in assets globally. On this platform, which we have been involved in since 2012, we continue to improve our sustainability performance in line with our environmental policy commitments. We also include our information and data regarding environmental management in our Annual Reports, which we are sharing with our investors and the public for several years.
