Solar power
Climate protection is a high priority for Vienna Airport. The airport is continuously reducing its CO2 emissions with many measures. Energy from the sun plays an important role in this: with a total of eight photovoltaic systems, Vienna Airport generates around 30 million kilowatt hours of electricity - this corresponds to the electricity consumption of around 7,000 households per year. This means that the airport covers about one third of its annual electricity demand with solar energy.

One of the largest photovoltaic plants in Austria
The photovoltaic plant is located south of runway 11/29 on a limited-use area at the edge of the airport area. With 55,000 panels on 24 hectares, this is the largest ground-mounted plant in Austria. Groundbreaking was in October 2021, commissioning will take place in May 2022.
More photovoltaic systems at Vienna International Airport
A further seven systems can be found on the roofs of Hangar 7, the old winter service hall, the Air Cargo Center, the area of the former sewage treatment plant, the new Office Park 4 and on the roofs of multi-storey car parks 3 and 8.
Numerous other measures for sustainability and energy efficiency
In addition to photovoltaics, Vienna Airport implements numerous other climate protection measures:
- For example, the airport operates an e-fleet with currently more than 380 e-vehicles
- The lighting systems are gradually being converted to energy-saving LED systems.
- Office Park 4, which will be commissioned in 2020, uses geothermal energy and has won several awards as Austria's most sustainable office building.
- A Smart City control software developed together with the Vienna University of Technology supports the energy optimisation of existing and future buildings.
