The Sustainability Graduate Program is designed to help you develop practical skills that you can apply immediately in your career. To achieve your degree, you’ll complete 12 courses.

Our core courses focus on learning research methodologies and building sustainability-specific skill-sets.

Our comprehensive selection of electives enables you to tailor your program to your personal or industry-specific interests.

Your thesis or capstone project will give you the opportunity to apply these skills to a real-world problem.

Study online and on-campus. You may take most courses online. You are required to attend your thesis or capstone course on campus.

Admission to the Sustainability Graduate Program

At Harvard Extension School, your admission is based largely on your performance in two specific Harvard Extension courses that you complete before submitting an application.

To get started, we invite you to explore the degree requirements, confirm your initial eligibility, and learn more about our unique “earn your way in” admissions process.

Failure is temporary. And you fail one day, and the next day what you learn from that failure becomes the seeds of success.

Learn From Industry Experts

A hallmark of the sustainability program is its versatility. You’ll choose from a diverse set of courses to design a curriculum that meets your unique needs and interests. And you’ll learn from Harvard faculty and industry leaders who help you gain real-world perspectives.

Cost and Financial Aid

Affordability is core to our mission. When compared to our continuing education peers, it’s a fraction of the cost.

Our Tuition (2021–22 rate) $3,100 per 4-credit course ($775 per credit)
Average Tuition of Peer Institutions $5,476 per course
Average Total Cost $37,200

After admission, you may qualify for financial aid. Typically, eligible students receive grant funds to cover a portion of tuition costs each term, in addition to federal financial aid options.

Learning & Connection

Deep learning springs from human connection. That’s why we work so hard to bring people together — whether in a live virtual classroom or an in-person seminar on campus.

Our approach to online learning fosters interaction without sacrificing flexibility. Each week, you’ll engage with your instructor, participate in peer discussions, and receive one-on-one support from teaching staff—all from your home or office.

What Can You Do With a Master’s Degree in Sustainability?

With a master’s degree in sustainability, you can change the world while building a community of friends and peers from around the world.

You might help your organization reduce its carbon footprint. You may design environmentally friendly products, reduce wasteful packaging, or develop a more sustainable supply chain. You could help ensure ethical corporate governance or bring your organization’s business practices into alignment with the interests of stakeholders and customers.

With a degree in sustainability, you’ll gain the knowledge and the flexibility to advance your career while making a positive impact on the environment.

Is a Degree in Sustainability Useful?

A graduate degree in sustainability creates the opportunity for you to pursue your passion while bringing about positive change. Careers in sustainability are rarely linear, meaning that you can create your own pathway.

You may want to bring sustainability to a specific industry you know well, such as fashion or finance. Or you may apply your unique skills or passion—such as urban planning, eliminating packaging waste, or food sustainability—to one of many industries.

Is a Career in Sustainability a Good Career?

As the fight against climate change grows more urgent, governments, nonprofits, and businesses increasingly need employees with green skills. In fact, job growth in sustainability is quickly outpacing the supply of individuals with the relevant qualifications.

Adding a master’s in sustainability to your resume may give you a competitive advantage in this job market. And it offers you the opportunity to play a vital role in keeping our planet healthy.

How Long Does It Take to Complete the Sustainability Graduate Program?

The sustainability graduate program at Harvard Extension School offers adults like you maximum flexibility, because we know that professionals with demanding schedules need to design their own path.

Interested in an accelerated journey? Enroll in consecutive terms or take multiple courses in a term. For a more moderate pace, you can take one course per term or even take a term off when you need to.

Most students take one or two courses each term. Once you complete the two courses required for admission, you have five years to complete all the degree requirements.
