The PhD programme in Sustainability Science is a three-year programme that aims to produce scholars who will become key researchers in the field of sustainability science. The programme takes an innovative approach to sustainability, seeking to promote a better understanding of the issues by incorporating global change perspectives, specifically those related to climate change and biodiversity.
The 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. The programme provides students with unique opportunities to interact with leading scholars and policymakers through lectures, international conferences, and workshops. 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. Through coursework and research, PhD students gain critical thinking and problem-solving skills, as well as the technical literacy required to address sustainability problems.
The programme starts in September, and by July of their third year students are expected to complete all of the course requirements, obtaining at least 14 credits. Students can select courses from those offered by UNU-IAS, while also enjoying the opportunity to take courses at other leading universities in Japan such as the University of Tokyo, Sophia University, and International Christian University.

Joint Diploma Programmes

Students of the UNU-IAS doctoral degree programme are also encouraged to pursue one of two joint diplomas in sustainability science, which are offered in partnership with the University of Tokyo Graduate School of Frontier Sciences (UT-GSFS), and with Sophia University. These diploma programmes require students to gain 18 credits, of which eight must be from courses specified by UNU-IAS and the partner university under the respective joint diploma programme. A joint diploma can only be awarded to students who successfully complete the two-year UNU-IAS master’s degree programme.

Learning Environment

UNU-IAS is a global university located in Tokyo, with all classes conducted in English. Sharing a building with many UN agencies, it offers a unique learning environment for its diverse and international student body. The PhD programme includes courses featuring more than 15 international guest lecturers from leading agencies and institutions, offering students opportunities to learn from their unique expertise and experience. The class sizes are sufficiently small and students benefit from interactive and personalized teaching.


The UNU Library offers access to a range of academic books, over 20,000 electronic journals, official UN documents issued since 1946, and publications in the International Monetary Fund, World Bank, and Organization for Economic Co-operation and Development e-libraries. All students are provided with a comprehensive library orientation session at the beginning of the course. Students also have access to the libraries of International Christian University, Ochanomizu University, Sophia University, Temple University Japan, and the National Graduate Institute for Policy Studies.

Project Research Opportunities

Our teaching programme is closely interconnected with UNU-IAS research activities across three thematic research areas (Sustainable Societies, Natural Capital and Biodiversity, Global Change and Resilience). Students have opportunities to gain practical experience by engaging actively in the institute’s research projects. Student research is expected to contribute to the project with which the student chooses to be affiliated; and students hone skills learned in the classroom by conducting research in the field alongside experts and seasoned practitioners.

Student Support

UNU-IAS assists students from the time of their registration to graduation, acknowledging that students may experience difficulties adjusting to a new country and culture.
An induction programme is conducted at the beginning of the academic session, introducing students to the staff responsible for specific student services, and familiarizing students with the campus through a tour of the facilities.


Students are provided with a handbook about living in Tokyo prior to their arrival, including information on how to find and secure accommodation.
