They take approximately two years to earn and are primarily used as a prerequisite for a bachelor's degree.

An accredited bachelor's degree program will require a four-year commitment and will include classes in political science, communications, business, basic math and science, the national park system, global warming, conservation efforts, and wildlife threats. The master's degree in environmental science is an interdisciplinary graduate program, focusing on the natural environment and environmental problems. Students in these programs learn about environmental threats in different regions, the natural science principles behind environmental problems, and policy issues surrounding environmental protection.

Online Bachelor's Degrees in Environmental Science

The online Bachelor of Arts in environmental science provides an interdisciplinary look at ecology, earth science, biology, geology, and other natural and social sciences. Students begin the degree with introductory courses in environmental science, which discuss basic scientific principles and major issues in environmental science today. These four-year programs explore the science of the earth from many different angles and often include coursework in pollution, water resources, ecosystems, and methods of protection, management, and restoration of environments. Other courses include public policy, climate change, and environmental law, as environmental scientists are often involved in crafting regulations surrounding environmental use.

Online bachelor's degrees also include an array of general education courses in topics like math, statistics, humanities, and other liberal arts areas. Communications courses, including English, history, and composition are important for environmental science students. Some schools allow students to earn credits by participating in internships with local environmental agencies and organizations.

Most entry-level jobs in environmental or green companies require at least a bachelor’s degree. Those with a bachelor's degree in environmental science can qualify for entry-level positions as environmental scientists and specialists. For those interested in environmental regulatory fields such as government agencies or consulting firms, it is imperative that geology courses are also part of the curriculum. While a bachelor's degree is sufficient preparation for most entry-level government positions, a master's degree is often necessary for employment in the private sector or for further career advancement.

The Importance of Accreditation

Accreditation is a process by which colleges, universities, and degree programs receive a comprehensive evaluation by an authoritative, independent agency. Legitimate accrediting agencies are recognized by the US Department of Education and will be found in the USDE database. While it isn't mandatory to attend an accredited school, doing so can provide you with a level of confidence that your degree program meets high academic standards and that it will be acceptable to graduate schools (should you decide to pursue a master's or doctoral degree), future employers, and licensing boards.

Accreditation is also important for students who wish to apply for scholarships or financial aid, as most organizations and lenders will only grant aid to students who attend an accredited school. Many professional licenses, such as a professional engineer license or a license to practice law, also require applicants to have a degree from accredited institutions. Visit the US Department of Education or the Council for Higher Education Accreditation for a list of accredited schools.

What Students Will Learn in an Online Environmental Science Program

Students who study environmental science will focus on current environmental issues, as well as the legal and financial restraints that govern the way environmental protection is approached politically. They will take a range of courses that explore scientific techniques and processes. A typical course may include the politics of energy, conservation biology, international economics, or the science of global warming. Undergraduate courses in environmental science often focus on practicality as opposed to theoretical approaches. Many schools offer internships as part of their degree, varying from field research to political internships. With more widespread acknowledgment of the impact of climate change, these opportunities are increasingly more present. 

Most master's degree students who study environmental science already have some sort of specialized interest that led them to pursue a degree in the first place. Those who do not will likely go on to select one after exploring their interests through a variety of classes. The specialization they choose will affect the courses they take, their thesis and research options, any internships or volunteer opportunities they participate in, and the kinds of jobs available to them upon graduation.

The following list provides an example of some of the courses that students may take in an accredited undergraduate or graduate environmental science degree program:

  • Chemistry or Geochemistry: All environmental science students will study chemistry. Most chemistry courses at the graduate level will focus specifically on geochemistry, or the major chemical processes that govern the way the environment functions. This class may also include an exploration of nuclear waste and the ways in which is it disposed.
  • Climate Change: This is one of the most fundamental classes to a degree program in environmental science. Topics include weather patterns, the rhythm of the tides, and dendroclimatology.
  • Energy and Sustainability: This class explores the ways in which environmental science work in conjunction with ecology, engineering, and even economics. Thermodynamics and the search for a sustainable fuel source are both important topics in the course.
  • Environmental Measurement: Measuring rainfall, air pressure, and wind requires delicate instruments that must be handled properly; however, the main focus of an environmental measurement class for environmental science graduate students will be utilizing and reading satellite images that help track major environmental changes over time. This may be one of the more technical classes in the program.
  • Geohydrology and Water Preservation: There are millions of people in the world who do not have access to clean drinking water, and because water is becoming increasingly polluted and scarce, many students who are studying environmental science will find that they have the option of taking a course in geohydrology or in water preservation.
  • Nonfiction Environmental Writing: In order to express independent, original thoughts and research in this discipline, students need to understand the precise writing style expected of them. Place narration and proposal writing will be included. 
  • Population Geography: This class focuses on how the patterns of movement and settlement exert an influence on the environment and the lay of the land. A specialty under the heading of human geography, students will encounter issues like immigration and mortality rates.

Career Specializations for Environmental Science Graduates

Careers in environmental science focus on protecting the earth's resources by identifying things that are harming it and working to reverse environmental degradation. In order to help realize these goals, environmental scientists work in both public agencies and private firms in a variety of specializations. Some work for the government, testing and analyzing environmental resources and suggesting policy items and regulations. Others work as consultants, helping businesses comply with government regulations and develop sound environmental practices. Academic environmental scientists may work on more theoretical research and may apply a variety of disciplines to the study of the environment, such as math and chemistry.

Job opportunities for students of environmental science are growing both in the public and private sectors. Recent congressional stimulus and budget packages have allocated hundreds of millions of dollars to clean energy and environmental research, which creates many grants and programs for professionals. Many NGOs (non-governmental organizations) rely on the research and work of students of environmental science to publish reports, lobby governments and to help ensure their practices meet state and federal guidelines. Even energy companies hire many environmental science graduates to analyze aspects of their businesses. In the public sector, many environmental science majors go into teaching.

Entry-level environmental science positions in government and some private firms typically require an undergraduate degree in environmental science, earth science, or a related area. Master's degrees are required by some consulting firms and are often necessary for advancing to higher positions. Environmental scientists at colleges and universities will usually need a doctoral degree in an environmental science area. Mastering the technology used in environmental science and earning the available professional certifications can also help an aspiring environmental scientist land a job.

Environmental science is an interdisciplinary field that provides many opportunities for specialization. During their undergraduate or graduate degree program, students can tailor their studies to focus on political, scientific, natural, or social issues. Determining which specialty is right for you may require some research. Here is a list of some possibilities:

  • Conservation Scientist: Conservation scientists often work as foresters who preserve and protect natural lands. They also manage habitats for various wildlife and protected lands. Licensing is required in some states in order to practice forestry.
  • Environmental Advocate: Environmental advocates navigate the political process and work for non-profit or lobbying firms to help erect, amend, obstruct, or pass laws regarding the environment.
  • Environmental Analyst: Analysts tend to work with a team helping to ensure that companies or organizations meet environmental regulations. In this case, it is beneficial to have certification in environmental risk management. 
  • Environmental Business Consultant: Corporations and businesses all over the world hire professionals who are dedicated entirely to improving a company's environmental record. They are hired as consultants to point out areas where corporations can decrease their carbon footprint and increase their positive impact on the environment.
