Program description
Degree awarded: PHD  Sustainability

The PhD program in sustainability prepares students to become scientists and leaders in research who investigate the urgent sustainability challenges of this century. The flexible, transdisciplinary nature of the program allows students to focus on problems of interest to them, drawing upon relevant knowledge from sustainability science and a variety of disciplines. This full-time program includes a high degree of faculty interaction and collaboration.

All sustainability doctoral students gain a better understanding of the need for a transdisciplinary approach to solving sustainability challenges as well as the ability to communicate their research effectively to academic and non-academic audiences alike.

In addition to the common learning outcomes, students are able to conduct research on particular sustainability challenges using theoretical lenses and methods from sustainability science and a range of complementary disciplines. Students learn to translate sustainability challenges to tractable research questions; develop a portfolio of quantitative and qualitative research methods to address these research questions; formulate and test hypotheses; utilize rigorous elicitation methods to gather qualitative and quantitative datasets; learn to engage with stakeholders to co-produce knowledge; use statistical and other analytic techniques to analyze data; and build and apply models of social-ecological systems.

They develop expertise in the analysis of institutional policies and regulations, as well as the design of the built environment and technologies, to support sustainable development. They also develop the foundational knowledge of concepts and methods required to conduct interdisciplinary and transdisciplinary research and effectively communicate their findings across academic disciplines, as well as to policymakers and the general public.

Graduates possess an advanced understanding of the dynamics of coupled social-ecological systems and use this knowledge to conduct original research to inform robust solutions to specific sustainability challenges. They are equipped to lead others in the development of sustainable strategies at the local, national and global levels.

STEM-OPT for international students on F-1 visas

This program may be eligible for an Optional Practical Training extension for up to 36 months. This OPT work authorization term may help international students gain skills and experience in the U.S. Those interested in an OPT extension should review ASU degrees that qualify for the STEM-OPT extension at ASU's International Students and Scholars Center website.

The OPT extension only applies to students on an F-1 visa and does not apply to students completing the degree through ASU Online.

Global opportunities
Global experience

Studying abroad is encouraged for graduate students. Nearly all of the College of Global Futures faculty-directed programs offer graduate credit. In addition, the Global Education Office offers more than 50 program opportunities, with programs on every continent.

Faculty-directed programs tend to be the best fit for graduate students; taking courses with ASU professors over the summer or during academic breaks offers students close mentorship and professional network growth in many fields of study while they earn ASU credit. Exchange program participation is also possible with careful planning.

Students can find programs specific to their interests on the College of Global Futures Study Abroad webpage, and additional opportunities and information on the ASU Global Education Office website. These sites also include additional information about applying for funding to support global travel.

Graduate students are also encouraged to apply for funding for international research, study and professional development through ASU's Lorraine W. Frank Office of National Scholarships Advisement.

Career opportunities

Professionals with expertise in sustainability frameworks and interdisciplinary research are in high demand across industries, including business, academia and government. Skills in critical thinking, teamwork, sustainability problem solving and research are valuable to businesses and institutions, many of which are in need of expertise to solve critical sustainability problems and introduce sustainability principles into their business models.

From the School of Sustainability's 2022 alumni employment survey, 100% of doctoral program respondents are employed. Of those respondents employed, 100% have jobs directly related to sustainability. Students can learn more about careers in sustainability and where graduates of sustainability doctoral programs are now employed by visiting the School of Sustainability's alumni employment data website.

Career possibilities for program graduates include:

  • chief sustainability officer
  • data analyst
  • environmental scientist
  • geographic information systems coordinator
  • professor
  • program manager or director

What are accelerated programs?
Accelerated programs allow students the opportunity to expedite the completion of their degree.

3 year programs

These programs allow students to fast-track their studies after admission and earn a bachelor's degree in three years or fewer while participating in the same high-quality educational experience of a 4-year option. Students should talk to their academic advisor to get started.

Accelerated master's

These programs allow students to accelerate their studies to earn a bachelor's plus a master's degree in as few as five years (for some programs).

Each program has requirements students must meet to be eligible for consideration. Acceptance to the graduate program requires a separate application. Students typically receive approval to pursue the accelerated master’s during the junior year of their bachelor's degree program. Interested students can learn about eligibility requirements and how to apply.
What are concurrent programs?
Concurrent degrees allow students to pursue their own personal or professional interests, earn two distinct degrees and receive two diplomas. To add a concurrent degree to your existing degree, work with your academic advisor.
What are joint programs?
Joint programs, or jointly conferred degrees, are offered by more than one college and provide opportunities for students to take advantage of the academic strengths of two academic units. Upon graduation, students are awarded one degree and one diploma conferred by two colleges.

What constitutes a new program?
ASU adds new programs to Degree Search frequently. Come back often and look for the “New Programs” option.
What are online programs?
ASU Online offers programs in an entirely online format with multiple enrollment sessions throughout the year. See https://asuonline.asu.edu/ for more information.
What is WRGP (Western Regional Graduate Program)?
The Western Regional Graduate Program (WRGP) provides a reduced tuition rate to non-resident graduate students who qualify. Visit the WRGP/WICHE webpage for more information: https://graduate.asu.edu/wiche.
