Environmentally friendly majors

If you’re interested in STEM fields, there are various ways to specialize in different aspects of the environment. Check out these degree options that you can find at colleges and universities across the country.

Environmental Studies

Environmental programs vary from college to college, with some leaning more toward laboratory science and others leaning toward social science. Environmental Studies is considered an interdisciplinary field of study because it interacts with so many other academic disciplines and connects with many aspects of our lives. Williams College, a liberal arts college in Massachusetts, is extremely proud of its Environmental Studies program, which was established in the 1960s and was among the first of its kind in the country. As Director of the Environmental Studies program and professor Nick Howe explains, Williams’ program is broad and diverse, allowing students to specialize in various areas of Environmental Studies, including Social, Economic, and Political.

Environmental Science

Environmental Science is considered more of a “hard science” view of the environment, with more focus on laboratory research and ecological scientific drivers. The University of Michigan describes its Earth and Environmental Sciences major as a program that provides “a foundation in the natural sciences, to understand how the Earth system works, and to tackle grand challenges facing our planet and society.” These types of programs involve more field research and education in the scientific processes of the environment. There’s generally less focus on the intersectionality of society and the environment.


Many colleges have programs of study for Sustainability. They often comes in the form of a minor-only program or concentration, which Colorado State University defines as “a specific field of study related to a major.” College Board’s Big Future website describes Sustainability Studies as combining interdisciplinary ideas and methods to take advantage of Earth’s natural resources and protect them for future generations. These programs integrate well into many fields, such as business, economics, urban planning, anthropology, and more.

Biology, or the study of life, isn’t just cells and humans—it also includes ecosystems and environments. Biology might be overlooked due to its popularity as a pre-med undergraduate major, but the biological sciences cannot be dismissed. Specialization in Environmental Biology, Marine Biology, Zoology, or Microbiology, among others, allows for intense work with the natural world. Rachel Carson studied Marine Biology and Zoology and used those studies to build the foundation of her work as an ecologist. 


Ecology is the study of the relationships between living organisms, humans, and the physical environment—a perfect for those looking for careers in environmentalism. Those majoring in Ecology gain an understanding of ecosystems and ways to use natural resources while keeping the Earth healthy. As in the many other fields of studies previously mentioned, students have opportunities to specialize in many areas, from Public Health, Biomedicine, Endangered Species, Agriculture, and more. This major’s versatility in many industries allows graduates to use their knowledge and passion for the environment in various sectors with the potential to champion for change in various areas from research to policy.

Environmentally friendly careers

Careers in the environment aren’t just limited to STEM majors. Studying Communications, Business, Law, Journalism, Political Science, and more can also bring you down an environment-based career path. There are many job possibilities that could not be covered in this guide, but here are a few examples to get you started.

Environmental scientist

According to the BJS Occupational Outlook Handbook, environmental scientists and specialists “use their knowledge of the natural sciences to protect the environment and public health.” These people may work in various settings: environmental agencies and organizations to clean up areas and conduct research, governmental and legislative sectors to advise and lobby policy, corporations and private industries to reduce waste from production processes, and more. Their work and research may focus on protecting public health, restoring ecosystems, or analyzing climate change.

Political organizer

Political organizers, also known as community organizers, are those who work in the political atmosphere raising awareness and advocating for certain issues. Environmentalists who don’t see themselves majoring in the STEM field may choose this career path. Organizers who work at environmental organizations and grassroots initiatives have one main goal: to reach out to and educate the community, encourage the public to take action, and hold elected officials accountable. For example, the Michigan League of Conservation Voters (MLCV) has a team of political organizers. They have many responsibilities from recruiting volunteers; coordinating phone banks, town halls, and other events; keeping the public updated on environmental issues in Michigan; and more. Organizers play a large, important role in environmental advocacy, helping communities better understand the critical environmental concerns facing them and ensuring elected officials hear the voices of public members about environmental issues they are prioritizing.

Environmental lawyer

Environmental lawyers are needed in law firms, corporate legal teams, public interest and advocacy groups, governments, and other work settings. Georgetown University defines environmental lawyers as those who represent clients in legal issues such as clean technology, water, climate change, and management of land subject to native title and other public land. Attorneys have a comprehensive understanding of both the administrative law and applicable regulations established by governmental environment agencies. Depending on where they work, they may push for enforcement, defend client actions, provide counsel to legislative bodies, and more. With increased attention on the environment, these attorneys may choose to focus on specific areas, including but not limited to water, energy, land, air, waste disposal, agriculture, insurance, and real estate.

Public sector

Many scientists are employed by the public sector: environmental scientists, biologists, zoologists, atmospheric scientists, and more. Several US governmental agencies’ works involve the environment. In the public sector, individuals conduct research, write reports, design projects, and shape environmental policy. Careers may be found at all levels of government, from local and state to federal. The Environmental Protection Agency (EPA), National Park Service (NPS), US Forest Service, US Geological Survey (USGS), and more employ ecologists, biologists, geologists, lawyers, and others.

Nonprofit sector

For those who want to work in advocacy, the nonprofit sector is full of opportunities for employment. Major employers include the World Wildlife Fund, Nature Conservatory, Sierra Club, Greenpeace, and more. These nonprofits exist at international spheres as well as on smaller, local scales.

This year has been tough for my family and myself, so receiving this scholarship has been a blessing in disguise! CollegeXpress has been an excellent resource in helping me prepare financially for college. Thank you again for this amazing opportunity!



High School Class of 2023

CollegeXpress helped open me up to many colleges that fit my interests. I’m only a sophomore in high school, so I like having a lot to look at, and CX does a great job of picking colleges that meet my wants. It's a great website that I'll continue to use until it comes time for me to apply for colleges. I also like that it notifies me through email with options to look at. Thanks CX!

CollegeXpress has helped me find scholarships for the colleges I applied to. It was very hard for me to find scholarships in the beginning that I was qualified for. My teachers recommended this website to find some, and not only did I find some scholarships but I also got to look into some schools I hadn’t heard of before. I was very happy to have discovered this website, especially with the coronavirus spreading all over as I can’t really go visit many colleges.

The college application process has been a stressful one, but CollegeXpress has eased some of that stress with its readily available college resources. At the beginning of the process, I frequently used the college search feature, and now that I’m almost done applying, I’ve started using the scholarship search. Both of these resources have made it easier to find relevant information.
