CELEBİ 2021 ANNUAL REPORT

30 Çelebi Ground Handling Inc. 2022 Annual Report 4. Benefits of Our Environmental Projects and Energy Efficiency Efforts The table below provides comprehensive details on the environmental and financial benefits resulting from the efforts that have been implemented to mitigate or eliminate our impact on the environment: Benefits of Our Environmental Projects / Energy Efficiency Efforts Project/Effort Environmental Benefit / Revenue Cost Savings Conversion of 26 Conveyor Belts, 16 Passenger Stairs and 1 High-loader Equipment, which are powered by diesel fuel, to electric power A total of 265.62 tons of CO 2 e greenhouse gas emissions have been prevented annually. An annual savings of TL 3,320,805 was achieved across various categories including fuel, maintenance, labor, and consumables. Conversion of our 26 electric tractors’ traditional lead-acid batteries to lithium- ion batteries A total of 215.65 tons of CO 2 e greenhouse gas emissions have been prevented annually. An annual savings of TL 1,325,866 was achieved through reductions in electricity consumption, maintenance, labor, and consumables, among other factors. A procurement of 9 electrical equipment was made, comprising of 3 Conveyor Belts, 2 Toilet Vehicles (LSU), 1 Clean Water Vehicle (WSU), 1 VNA, 1 GPU, 1 Passenger Ladder, and 21 lithium-ion batteries (luggage tractor). Following the procurement, previous fossil fuel-based equipment within the fleet was replaced with newly acquired units. A total of 248.83 tons of CO 2 e greenhouse gas emissions have been prevented annually. An annual savings of TL 3,766,400 was achieved across various expenses such as fuel, maintenance, labor, and consumables. Preventing the usage of paper as a result of the digitization of business processes carried out with printed documents in our Human Resources department A total of 226,542 A4 sheets were saved annually. Thus, the prevention of 1,051 kg of CO 2 e greenhouse gas emissions per year has been achieved. An annual financial savings of TL 31,700 was attained. Ensuring waste oil recycling resulting from our equipment maintenance activities An annual recovery of 30 tons of waste oil was achieved. Thus, the emission of greenhouse gases resulting from the energy needed for the transportation and disposal of mineral waste oils is avoided, while also preventing the depletion of natural resources and energy consumption required for the production of mineral oil from scratch. An annual financial savings of TL 10,200 was achieved. Additionally, the table below outlines the specifics pertaining to the energy consumption and emission reduction attained from the energy efficiency projects that we have executed: Energy Efficiency Projects Project/Effort Greenhouse Gas Emission Reduction (tons CO 2 e /year) Reduction in Energy Consumption (kWh/year) Integrating 10 conditioned ventilation facilities in our IGA Cargo Warehouse building into the automation system to ensure optimal efficiency 6.09 12,740 Converting a total of 622 T8-type lights to LEDs (422 at our Antalya Station and 200 at our Sabiha Gökçen Airport Station) 54.23 113,396 At our Sabiha Gökçen Airport Station, enhancing the physical infrastructure, optimizing insulation, implementing automated continuous heat monitoring and control to minimize the heat losses in the system room. 6.09 12,285 BOARD OF DIRECTORS 2022 Annual Report
