The Doctor of Philosophy in Sustainability Science Programme is a three-year programme that takes an innovative approach to sustainability, seeking to promote a better understanding of the issues by incorporating global change perspectives.

This programme will equip graduates with comprehensive, multidisciplinary knowledge of sustainability problems, and deepen their understanding of the role of environmental sustainability in addressing current issues related to global change, specifically those related to climate change and biodiversity. Students undertake problem-oriented research by playing an active role in UNU-IAS research projects, and acquire the quantitative and qualitative analytical skills necessary to understand the underlying principles of various systems involved in sustainability issues and debates.
