Towards the goal of a climate neutral city in 2040, many sectors have to be integrated and many actors have to be brought together. It requires organisations to change and complex decisions to be made in a different way. In order to align decision making of various stakeholders like politicians, officials, businesses, citizens with the roadmap to climate neutrality, clear and solid information must be provided. Such an information base for decision making includes breaking down long-term goals to yearly goals, demarcating their spatial origins and effects, providing comparability to national and global goals and comparing the goals with the actual progress of today’s measures. As the time is running, we need to do such analysis regularly in order to be able to make decisions on how to adjust our measures. Digital tools could support this iterative decision making process through analysing and visualising emissions generated from energy production, heating and cooling buildings and mobility. Moreover, tools could take into account costs of measures, demografic change, material/energy budgets and trade-offs between sectors.

The city of Vienna is focusing on the increased expansion of renewable energies. Thousands of houses and apartments are to be climate-proofed for this purpose. This will save CO2 in the long term and sustainably. How much CO2 can be saved by switching to renewable electricity and heat supply in a building? What factors - age of the building, room volume, heating systems, etc. - do we need to take into account? The goal of the challenge is to design a tool that enables an estimate of the CO2 savings when converting a building.

The City of Vienna has introduced an environmental management system - PUMA (Program Environmental Management in the Municipality), which has already been rolled out in all municipal departments. The departments have their own environmental manuals and have introduced measures to improve the environmental impact of their own services in the areas of energy, mobility and waste management. All implemented measures can be seen in a list that will be made available for the challenge. The success of practically all measures depends on the proactive participation and commitment of the employees. How can employees be motivated via a tool to consistently comply with the measures; to make their own behavior even more environmentally friendly; to improve CO2 savings, energy savings and resource conservation; and to develop further ideas for environmentally friendly solutions and behaviors? How can they be supported by a tool to understand the environmental impact of their own behavior in a playful, easy and understandable way – for example via visualizations or comparisons? The goal should not be to create pure calculations (e.g. CO2 calculator).

Challenge provided by the Intergenerational Digital Service Learning (IDOL)-project:

In recent decades, people's life expectancy has risen significantly. This means that the proportion of the elderly population is increasing, also in Vienna. The older generation plays an important role in building a climate-friendly city, while at the same time their special needs and age-related vulnerability have to be taken care of.

In old age, the immediate living environment becomes more and more important - in Vienna, this is the Grätzl. If driving a car is no longer possible for financial reasons or public transport can no longer be used for health reasons, older people are restricted in their autonomy and have difficulties in accomplishing their everyday tasks such as doing their groceries. They are dependent on the help of others if they want to live in their familiar surroundings for as long as possible.

To meet this challenge, the following questions need to be asked: How can older people stay in their homes and be supported with their daily needs, such as doing groceries, if they do not have family support? How can this work in the Grätzl in a generation-friendly and climate-neutral way? How can a digital solution look like that helps to organise groceries for older people? How does this digital solution need to look like so that older people are able to use it?

The goal of this challenge is to find a solution that helps older people to stay in their Grätzl for as long as possible and to support intergenerational living in a climate-friendly way.

We want to create a climate-friendly way of living together. How can digital solutions help us to act in a climate-friendly way and to design effective climate measures, or how can corresponding prototypes look like?

With re-use, recycling and a longer life span of products, we can create a climate-friendly living. The circular economy encompasses many areas of people's lives from food supplies to electronic goods. How can we create even more awareness about recycling and preserving the lifespan of goods and products? What tools are available to make it easier for people to reuse and repair?

Vacation travel costs money and CO2 – but not necessarily. Even apart from the Prater and the Danube, we can travel with low CO2 emissions. But we need tools that help us plan our vacation and organize the trip. What digital solutions are there or can be conceptualized for planning a low-CO2 vacation?

A jury will assess the teams' pitches and will award €1.000 prize money, provided by the City of Vienna.

The City of Vienna is open to a further collaboration on relevant and interesting projects arising out of the Hackathon. 

The all-female winning team of the Hackathon 2023 will receive the opportunity to present their successful idea at the #DIDAYS23.

Fill in the application form here.

Students and early career researchers from all disciplines can apply, either as a team or as individuals. Programming skills are welcome, but are not essential for participation (we are looking for prototypes or concepts for a possible digital solution).

You will work in interdisciplinary teams, it is not about programming, but about concidering various aspects when working on a prototype/concept for digital solutions.

Teams will be evaluated by a jury.

We will host the Hackathon for a maximum of 30 people.

You may come with your own team or be matched with other participants to tackle challenges around the topic of Climate and Sustainable Development Goals. You will be advised by people from the industry, technical experts, and policymakers. The whole Hackathon will be free of charge and food and drinks are on us.

You will work in teams on a challenge within the limited timeframe and prepare a pitch in front of the jury. The focus is on developing a prototype or a concept for a digital solution (programming skills are not mandatory. There are convenient tools that do not require programming skills, such as design software, whiteboards that help you visualise your project. Remember, you will be working in teams).

The final pitch in front of the jury is the one that counts, they will decide on the winning team! Prepare well for it.

What you will do with your ideas after the hackathon is up to you! Whatever you plan – whether it’s founding a social business or further developing your ideas together with experts from our cooperation partners: we’ll support you! We do not claim any rights on your projects.

You register as an individual: on the first day of the event you will meet the other participants, we will prepare some getting to know each other exercises and teams will be matched on site

You register as a team: your team can consist of a maximum of four people, every teammember to register separately, please enter a name for the team.
