  • Overview
  • Agenda
  • Embark on a unique hackathon tailored for tech-savvy specialists in the dynamic fields of energy, sustainability, and digitalization! This exclusive event focuses on leveraging digital tools and data to drive and champion a green transition, the most significant change of our era.

    University of Tartu together with Garage48 invite you to transform your digital expertise into solutions for a sustainable future. Let's turn our hackathon ideas into tangible, impactful projects and pave the way for a greener tomorrow!

    The hackathon is brought to you in partnership with Cleantech Estonia, Environmental Investment Centre, Startup Estonia, Estonian University of Life Sciences, Nordic Council of Ministers, Tehnopol and sTARTUp Day.


    Our hackathon revolves around a central question: How can digital skills, knowledge, and data be wielded to foster the societal change we aspire to achieve? Join us in co-creating innovative solutions under the mentorship of industry experts and state representatives, ensuring that the proposed ideas are not only visionary but also feasible within specific domains.

    We're actively seeking cutting-edge tools and services to facilitate the transition away from fossil fuels, nurturing and advancing our green journey. Embrace the power of incentivizing and co-creation, as your ideas can shape policies and contribute to a positive impact on the future. Entrepreneurs play a crucial role in envisioning the utilization of data and services that could attract them to the region and towards more green products, fostering a more vibrant ecosystem.


    Our societies are undergoing active change on two fronts – digitalisation and green transition. This poses challenges and opportunities. Addressing climate change and energy crisis on an individual, municipal and national level comes with a sense of urgency. At the same time, we face digitalisation on every level, which comes with collecting large sets of diverse data.

    Local municipalities often grapple with challenges in supporting large-scale change. Your ideas on how small tweaks in local governance can enhance efficiency and deliver better results are essential. To fully achieve the transition, we also need insights into individual behavior changes and broader macro-level shifts aligning with our mission.


    We will meet at the heart of Estonia’s green transition region – Ida-Virumaa. The hackathon will take place in Jõhvi Concert Hall

    You will be provided with catering and access to the venue throughout the whole event. This includes sleeping spaces at the venue - pack your mattress, sleeping bag and pillow with you. The location is easily accessible by train, bus and car.


    • The top team will receive consultation and support services for developing their idea further, with a total award pool of 3000€.

    • Inspirational study trip for the best three teams to visit the startup ecosystem in Tallinn to learn more on how an idea becomes a real startup.

    • An hour of consultation with Cleantech on how to develop your idea into a real solution.
    • sTARTUp Day 2025 tickets to the whole team.


    To introduce the green transition challenge, potential of the data, and share some great examples of the digi+green solutions out there, we’ll host a webinar on April 23 at 18.00-20.00 EEST. SIGN UP HERE.

    We'll be preparing you a data overview for the hackathon, coming soon.
