If you’re passionate about making a positive impact in the world, sustainability and global development both offer meaningful professional pathways.
These two overlapping fields tackle some of today’s most pressing challenges. But the academic programs — and the careers they can lead to — have a few differences. In this article, we compare the difference between sustainability and global development, the skills you need to excel in either, and how to decide which field is right for you.
How the Sustainability and Global Development Fields Overlap
Before we begin comparing academic pathways and career opportunities, let’s define the fields and take a look at how they overlap.
What is Sustainability?
Focuses on building systems and initiatives that allow us to continue into the future without depleting our planet’s resources — and can also entail social and economic stability.
What is Global Development?
Focuses on sustainable solutions for improving agriculture, education, governance, human rights, technology, safety, and security — especially in developing nations.
Both fields share a commitment to building a more sustainable future. And perhaps you are drawn to both fields because of this very intersection: a concern for our planet and its people.
Those shared values are reflected in the United Nations’ 17 Sustainable Development Goals, which include ending poverty, eliminating hunger, providing clean water, improving educational access, reducing inequalities, and boosting employment opportunities. Achieving many of these goals takes dedicated people working on the ground in both sustainability and global development capacities.
A specialized master’s degree is an ideal way to gain the skills and knowledge required for the many in-demand roles in either (or both) fields. Harvard Extension School offers graduate programs in Sustainability and Global Development Practice. But which to choose?
Comparing Programs: Sustainability Master’s vs. Global Development Practice Master’s at Harvard Extension School
To help determine which HES graduate program — sustainability or global development practice — is right for you, start by looking at the curriculum and real-world learning opportunities. Which courses excite you? Which classes can build on any existing expertise or professional experience? If you’re already in a related field, what can you apply to work immediately?
What you will study in the sustainability master’s program
The Harvard Extension School Sustainability Master’s Degree Program curriculum combines courses and applied research to build practical expertise in climate strategy, environmental systems, and sustainable development. Through a range of required and elective courses, you’ll learn to evaluate complex challenges and develop solutions that can be applied across industries and sectors.
Example courses include:
- Leading with Ethics: Professional Practices for Sustainable Development
- The Carbon Economy: Calculating, Managing, and Reducing Greenhouse Gas Emissions
- Climate Adaptation: Planning and Policy
- Life Cycle and Supply Chain Sustainability Assessment
- Water Resources Policy and Watershed Management
With the sustainability master’s program, you can gain deeper specialization(s) and earn stackable graduate certificates along the way. Options include managing climate change, sustainable food systems, and corporate sustainability and innovation.
The sustainability master’s degree program also requires a thesis or capstone project, in which you will come to Harvard’s campus to share your thesis research design or your final capstone project with faculty and peers.
HES alumni take: Why they chose sustainability
Derrick Amoako, ALM ‘26, was seeking the opportunity to develop his knowledge in the food industry, especially as a research and development manager. The learning happened in real time — he could apply what he learned through Harvard Extension School’s sustainability curriculum in his career right away.
“The field of sustainability demands systems thinking: looking end-to-end, understanding who and what is affected, and anticipating second- and third-order consequences,” he says. “Over time, that mindset became embedded in how I approach my work and leadership.”
What you will study in the global development practice master’s program
The Harvard Extension School Global Development Practice Graduate Program curriculum focuses on global issues and impacts in areas like health and wellness, ecological systems, technology, and finance. Through hands-on projects, you’ll put ideas into practice as you identify problems, gather evidence, and create an action plan to address a pertinent global issue.
Sample core and elective classes may include:
- Global Development Theory and Practice
- The Economic Foundations of Global Development
- Food and Greed: Implications for Human Health and Sustainability
- Water Crises and Solutions: Engaging Science and Social Science to Develop Sustainable Solutions
- Sustainable Cities
- Development Finance Institutions
The global development graduate program also allows you to develop a specialty and earn a graduate certificate along the way. Related stackable certificates include environmental policy and international development. You also complete a capstone project focused on consulting, innovation, or a case study.
HES alumni take: Why they chose global development practice
Javier Jimenez, ALM ‘23, wanted to pursue global development practice because the course offerings aligned with his career as an NGO leader.
“Courses in policy analysis and sustainable economic strategies deepened my understanding of global challenges, allowing me to apply a holistic approach to problem-solving in my work,” he says.
Paulene Maria Isabella Santos, ALM ’21, who lives in the Philippines, was drawn to the program for the potential impact she could make. “Working in the development sector gives you an opportunity to create a tangible impact in the world, even in a small way,” she says.
Comparing Sustainability and Global Development Careers
Choosing between a sustainability and global development practice master’s program also means considering your post-degree plans. The good news: either degree will help you build a solid foundation for a career in the public and private sector.
The 2025 LinkedIn Green Skills Report shows the demand for green talent has grown by 4.3 percent in all countries surveyed. The fastest-growing areas are in renewable energy production, technology and media, and energy management. The World Economic Forum Future of Jobs Report 2025 also cites big growth in environmental stewardship careers. As organizations, governments, and communities around the globe increasingly prioritize a sustainable future for humanity, opportunities will only continue to grow.
What can you do with a degree in sustainability?
Sustainability careers are found in a broad range of industries from biotechnology and transportation to venture capital and clean energy. Within those areas, professionals could work in corporate sustainability, strategic communications, sustainable investments, financial planning, research, and other functions.
HES alumni have pursued sustainability careers with employers like the United Nations, The Nature Conservancy, GE, Bank of America, FedEx, and Tripadvisor.
What can you do with a degree in global development practice?

Career Advancement and Enhancement: Putting a Degree in Sustainability or Global Development Practice to Work
Whichever path you choose — sustainability or global development practice — a graduate degree can change your career in different ways. Perhaps it can help you expand your impact where you already are, or maybe it will open doors for where you want to go next.
Kiron Bhaskar, ALB ‘18, applied what he learned in the sustainability master’s program to his current employer several times over. “We have a sustainability-oriented employee resource group, and I was able to conduct a lecture series to improve awareness among my peers,” he says. “I also worked with that team to … improve aspects of sustainability relating to energy consumption, water use, waste management, etc. within the facility.”
Since completing his degree at Harvard Extension School, he has been promoted twice within his company and currently serves as the director of global systems engineering.
For Santos, the global development practice degree created new opportunities. “I became more qualified for the kind of jobs I wanted to be doing in the next phase of my career. It also allowed me to move more freely across the different thematic issues under the sustainable development framework,” she said. “I never would have thought, for example, that I could be working on the gender and climate change nexus.”
These alumni experiences point to a broader outcome: Harvard Extension School’s sustainability and global development practice programs prepare students for in-demand careers across industries and around the world, including in emerging fields and roles that don’t yet exist.
