Promoting sustainable development is one of the most complex challenges we face. Feasible and effective solutions require an international and interdisciplinary understanding. The fourth volume of the Young Sustainability Law Conference aims to contribute to legal research in this field. It brings together contributions from early career researchers from around the world who take an in-depth look at comparative, interdisciplinary and intradisciplinary aspects of sustainability law. The overarching goal of the contributions is to open up new perspectives for sustainability law and its further development. Simultaneously, the volume highlights the major transformative potential of sustainability law and need for further research in this area.
