A warm summer’s day in Vienna. Amongst the tree-lined streets, newly planted trees provide shade, whilst a bus pulls up almost silently at a WienMobil station. People are changing modes of transport – from bike to tram, from a shared car to the underground. What is everyday life for the people here is part of a bigger plan: Vienna is actively shaping the city of the future.

For the Austrian capital wants to be more than just digitally connected. Vienna demonstrates what a smart city can look like – one that is not only efficient but, above all, liveable.

Climate strategy rather than technological gimmicks

Vienna is rethinking the smart city – not as a purely digital project, but as a comprehensive response to the climate crisis. With its “Smart Climate City Vienna” strategy, the Austrian capital is pursuing a clear goal: climate neutrality by 2040. This is not just about technological innovations, but about a fundamental transformation of energy, mobility and urban development.

A key area of action is energy supply: projects such as the deep geothermal plant in Aspern demonstrate that Vienna is committed to renewable heat sources in the long term. At the same time, the city is driving the phase-out of fossil fuel heating systems through the “Raus aus Gas” initiative. The aim: a resilient, emission-free infrastructure that ensures a city worth living in for future generations too.

Aspern as a real-world laboratory for the future

Vienna’s smart city approach is particularly evident in Seestadt Aspern, in the east of the city. This is the site of one of Europe’s largest urban development projects – and at the same time a testing ground for sustainable innovations. Energy-efficient buildings, smart grids and new mobility concepts are directly integrated here. More than 25,000 people are expected to live here in future. In addition, Vienna will create around 20,000 jobs and training places here over the coming years.

Vienna is also setting a clear course in the transport sector: hydrogen buses, sharing schemes and WienMobil stations connect different modes of transport and make climate-friendly mobility suitable for everyday use.

This is complemented by new logistics solutions such as the “WienBox”, designed to make delivery traffic more efficient and environmentally friendly. Vienna’s municipal utilities have now installed such large parcel boxes at 240 locations across the city, with a total of just under 10,000 compartments – the result: delivery drivers are much faster and produce fewer emissions because they can skip “the last mile” to the front door and the respective letterbox.

At the same time, the city is investing heavily in adapting to climate change. Programmes such as “Raus aus dem Asphalt” (Off the Asphalt) or so-called “Cool Zones” create more green spaces and reduce heat islands in the city – an increasingly important factor for quality of life in urban areas.

The city belongs to the people

What sets Vienna apart from many other smart cities is its consistent focus on citizen participation. The city does not view transformation as a top-down process, but as a collective endeavour. Participatory formats, participatory budgeting and collaborations with research institutions ensure that people are directly involved in all innovations. This approach is paying off: acceptance of change is high, and many projects benefit from local knowledge and commitment.

In Vienna, therefore, ‘Smart City’ means not only more efficient systems, but also greater involvement of the urban community.

A European model with a signal effect

Vienna demonstrates that a Smart City can be far more than a digitally connected space. The combination of climate protection, concrete flagship projects and active citizen participation makes the city a role model for the whole of Europe. The path to a climate-neutral city is complex – but Vienna proves that it is achievable when technology, politics and society work together.
