The air quality in the airport area is a consequence of road and air traffic emissions, airport activities, heating of the airport facilities and other facilities from the wider local area.
The air quality in this area depends primarily on the inflow of polluted air masses coming from the direction of Ljubljana and Kranj, and also on weather conditions. In the airport area we use cooling and air-conditioning devices, and heat pumps which contain substances harmful to ozone.
The volume of air traffic in 2022 has still not reached the levels from the pre-corona period, which still had impact on the rules of ACA (Airport Carbon Accreditation) certification programme scheme for the reduction in the impact of greenhouse gases, run under ACI Europe, the association of European airports. Already in 2020, the association ACI Europe decided to adjust the accreditation rules in such a way that the data on carbon footprint for 2020 are not taken into account in the future applications for renewal or extension of the accreditation. The reason lies in the fact that the vast majority of airports have difficulty proving a reduction in the relative carbon footprint for the period 2020-2022 due to drop in passenger numbers compared to the pre-corona time. Namely, energy consumption and consequently air emissions cannot be reduced as quickly as the number of passengers. There is a minimum energy consumption (and associated air emissions) which is necessary for the airport to stay open and in operation, even with a reduced number of flights and passengers. Therefore, in the current situation facing airports, the only appropriate indicator is the absolute carbon footprint. The analysis of carbon footprint calculation (not including year 2020) are shown below.
Compared to the past three-year average (2018-2019 and 2021) the absolute amount of CO2 emissions were reduced for a 12%. Based on the data on the number of passengers and the weight of cargo for 2022, air emissions increased by 19% per passenger compared to 2018-2019 and 2021 period, or decreased by almost 22% per 100 kg of cargo. Compared to 2021, an increase in carbon footprint was recorded in 2022 in segment of electricity, company's vehicles and generators. On the other hand reduction in carbon footprint was recorded in segment of heating. While the total emissions (scope 1 and 2) decreased by 3%.
Efficient energy consumption, use of renewable energy sources or environment-friendly energy products, and reduction of CO2 and other greenhouse gas emissions are considered important environmental commitments of the company Fraport Slovenija.
We also defined key energy efficiency indicators. Fuel and energy consumption are checked regularly. In 2022, we consumed 6,876,582 kilowatts of electricity, which was 100% generated from renewable energy sources, 200,241 m3 of natural gas (NG), 19,477 L of liquefied petroleum gas and propane (LPG), 45,272 L of extra light heating oil (HO), 110,969 L of diesel and gas oil, 9,549 L of gasoline, and 1,286 L of kerosene.
In accordance with the company’s energy strategy and its commitment to preserving the environment, the construction of the central power facility was completed in 2019, which provides efficient supply of heat and cooling energy for the entire airport territory in one place. In its design, the plant combines the advanced technological and environmental systems of heating elements. Natural gas is used as the main fuel for heating boilers. It is modularly designed and allows expansion of energy facilities for further ten years.
In November 2021 and in partnership with Resalta as the project provider, a solar power plant on the roof of the parking garage started operating that helps to achieve the long-term goal of reducing CO2 emissions and lowering energy costs. In 2022 power plant generated 579 megawatts of renewable electricity, which covers 8% of the airport's total electricity consumption. As a result, 211 tons less CO2 emissions were released into the atmosphere. Investments in the construction of new solar power plants will continue in 2023.
Our mobility plan is aimed at encouraging our employees, business partners, passengers and airport visitors to change their travel habits, use cars reliably and rationally, and to opt for a sustainable means of transport.
The company is aware of the difficulties with the mobility and accessibility in terms of sustainable means of transport, thus the mobility plan tries to comply with these limitations in the best way possible.
The airport is namely connected with neighbouring settlements through a public transportation network. However, our employees cannot use it due to the shifting nature of their work. Thus, employees mainly use cars to get to work, since the existing traffic infrastructure is quite inconvenient and unfriendly for walking or cycling. However, years ago we started to encourage the use of electric vehicles for short business trips.
