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

With a master’s degree in sustainability, you’ll gain the knowledge and flexibility to advance your career while positively impacting the environment.

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

Is a Degree in Sustainability Useful?

A graduate degree in sustainability allows you to pursue your passion while bringing about positive change. Careers in sustainability are rarely linear, meaning you can create your own path.

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

Is a Career in Sustainability a Smart Choice?

As the fight against climate change grows more urgent, governments, nonprofits, and businesses increasingly need employees with green skills. In fact, the number of jobs 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 — while helping you play a vital role in keeping our planet healthy.
