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 recovery of air traffic during the pandemic is slower than originally planned, which still have 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 and which Fraport Slovenija joined in 2013. Therefore, the association ACI Europe decided to adjust the accreditation rules for 2021 as well, especially as the vast majority of airports have difficulty proving a reduction in the relative carbon footprint for 2021 due to significant drop in passenger numbers compared to the pre-corona time. The association already decided in 2020 not to take the data on carbon footprint for 2020 into account in the future applications for renewal or extension of the accreditation. Therefore, in the current situation facing airports, the only appropriate indicator is the absolute carbon footprint.
Compared to the past three-year average (2017-2019) the absolute amount of CO2 emissions were reduced by almost 13%. Based on the data on the number of passengers and the weight of cargo for 2021, air emissions increased by 253% per passenger compared to 2017-2019 period, or decreased by 23% per 100 kg of cargo.
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 2021, we consumed 6,200.705 kWh of electricity, which was 100% generated from renewable energy sources, 361,264 m3 of natural gas (NG), 21,141 L of liquefied petroleum gas and propane (LPG), 25,719 L of extra light heating oil, 94,368 L of diesel and gas oil, 9,122 L of gasoline, and 394 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 partnership with Resalta as the project provider, it built a solar power plant on the roof of the parking garage and the adjacent office annex. The power plant, which started operating in November 2021, generates around 530 MWh of electricity a year. Renewable electricity is generated by 1,347 high-quality photovoltaic modules, and covers 7% of the airport's total electricity consumption. It is estimated that this will reduce CO2 emissions by 200 tonnes per year. The cost of the project, which helps to achieve the long-term goal of reducing CO2 emissions and lowering energy costs, is estimated at €350,000. This is the first project of this kind, but certainly not the last, implemented at the airport.
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.
