The Sustainable Business Battle (SBB) is a business case challenge in which 10 interdisciplinary teams of students will compete to find the most sustainable, innovative and at the same time implementable solution. Students will be matched with one organization for who they will solve a business case.

In 2017,  the battle was initiated by four students of Leiden University supported by Leiden University Green Office, all MASCQ student associations and several (sustainability) parties from the region. As the first edition proved to be a huge success, it has been decided to make the SBB an annual battle organised by an independent student board.

The SBB is unique with its regional approach: Complex global issues shall be made concrete by translating them into an issue from our own region.



The SBB is for students and recent graduates from Leiden University, TU Delft and the Haagse Hogeschool. However, students of universities (of applied science) from outside the region are also very welcome to join! As a participant, you will gain skills and experience in sustainability and consultancy. We believe in interdisciplinary collaboration as a strength and are therefore looking for people from various backgrounds in their academic fields, country of origin and set of experiences. These students do not need to have any prior knowledge of sustainability, as we will form interdisciplinary teams where different backgrounds form strong teams. We also organise workshops to give you all the right tools to start with. So no matter whether you study background lies in sustainability, social sciences, beta studies, in humanities or in any other field, you are welcome to apply for the SBB.

The participants will be paired up with an organisation from the region. If you are intested in joining the SBB as an organisation, have a look here.



The Sustainable Business Battle (SBB) is a 3-week business case challenge in which ten interdisciplinary teams of students compete to find the most sustainable, innovative and yet implementable solution on a core-business related topic.

These questions are real challenges that organizations face. In order to solve the case, technical knowledge about sustainability is not needed. We are looking for small-scale out-of-the-box solutions for large-scale problems.

Students will be assigned to interdisciplinary teams consisting of four students. Every team will work on one business case provided by one institution.
