Klagenfurt, AT

The city of Klagenfurt is located in the Southern part of Austria and has a population of approximately 100,000 inhabitants. To show its commitment towards sustainable urban development, the city joined the Covenant of Mayors in 2011 and has consequently designed its own Sustainable Energy Action Plan.


As part of its strategy to transform Klagenfurt into a Smart City, the municipality has committed to reduce its CO2 emissions by 20% by 2020, 40% by 2030 and 90% by 2050. To achieve these objectives, the city intends to tap the potential of renewable energy generation and increase the energy efficiency of its building stock while developing innovative solutions to lower greenhouse gases emissions from the transport sector. To this end, Klagenfurt has already built a biomass heating system supplying the whole district heating network with 80% renewable energy. In addition, Klagenfurt has participated in the European project Cities on Power to evaluate the potential of the city for solar energy generation. Additionally, the municipality has also taken part in several European and national projects focused on the reduction of greenhouse gases emissions in the transport sector and has already adopted an ambitious plan for the energy efficient renovation of the city’s building stock.


In the framework of the Replication Cluster, the city of Klagenfurt intends to share ideas and experiences on the development of innovative solutions for renewable energy generation and CO2 emissions reduction with other European Smart Cities.
