What You’ll Learn in an Online Environmental Science Bachelor’s Degree Program

Environmental studies online degree programs typically consist of foundational major-related core and elective courses related to the examination and prevention of environmental pollution and the preservation of natural resources. A substantial portion of your course load will focus on the subjects making up your specific major (e.g., environmental science, environmental management, sustainability, etc.) and chosen concentration.

As indicated in the program spotlights above, most environmental science students also spend time in the field conducting hands-on research as part of an internship or practicum experience or to meet the requirements of individual courses. The common courses detailed below are a deep dive into the topics and specialties encountered by online environmental science degree students.

Common Courses

Most environmental science degree programs, whether online or on-campus, share foundational course subjects covered within their core curriculums. Five of the most common are discussed below, but remember that the actual titles of the courses covering these foundational subjects vary from program to program.

Climate Science

An examination of the science of climate change, climate science covers identification and analysis of the factors that create climate and exacerbate climate change both locally and globally. Also includes an assessment of past, present, and potential future climate changes through the application of various models, observations, and lab-based exercises.

Ecology and Ecosystems Studies

Overviews the interrelationship of organisms with each other and their environments at the population, community, ecosystem, and biosphere levels. Students learn to identify and apply ecological principles and scientific reasoning resulting in informed decisions regarding issues affecting ecosystems and environmental management. These courses often include hands-on field experiences.

Environmental Chemistry

Anintroductory course examining the fundamental principles of chemistry in relation to environmental systems, environmental chemistry discusses general chemistry principles including the nature of atoms, bonding types, chemical interactions and reactivity, and foundational groups. It also surveys chemistry/environmental topics like the migration of chemicals through the environment, biogeochemical cycles, and the science underlying air, water, and land pollution.

Principles of Biology

Examines the basic and advanced principles of biology as they apply to the range of applications in environmental science. Specific areas covered depend on a student’s particular academic focus within the environmental science field. For example, students concentrating on aquatic science focus on microbiology, while those concentrating on Earth science focus on geobiology. Most curriculums also include biology labs.


Introduces basic concepts of descriptive and inferential statistics related to environmental science research. Topics include data collection and sampling methods, concepts of probability and probability distributions, hypothesis testing, chi-square tests, correlation and regression, and the use of statistical software. This is a foundational course for most environmental science curriculums, especially those for sustainability and environmental management programs.

Popular Specialization Options

Given the breadth of the environmental science job market, environmental degree students can benefit from tailoring their studies. Most online environmental science programs offer specialization options, minors, or elective course choices, though options vary significantly among programs. Below are five popular specialization options currently available from one or more online environmental studies online degree programs.

Earth Systems

This concentration undertakes a comprehensive examination of the Earth’s major systems (i.e., geosphere, biosphere, atmosphere, hydrosphere, and cryosphere) and their interrelationships to better understand global environmental changes, both natural and manmade. Particular emphasis is given to the sociopolitical and economic influences of those systems and the challenges related to climate change.

Economy, Sustainability and Society

This is a cross-disciplinary concentration focusing on the interrelationship between environmental science, sustainability, economic policy, and business and the social sciences. Coursework covers topics like natural resource conservation issues, environmental politics and policy, the impact of renewable energy resources, the social valuation of environmental systems, environmental ethics, and more.

Environmental Agriculture

Students selecting this concentration examine current and future issues and innovations in sustainable agriculture practices – and their social and environmental consequences – from local and global perspectives. Course topics include animal science, soil science, genetics, food systems, crop production and ecology, organic farming, agricultural business management, urban forestry, and many more.

Natural Resources and Conservation

For individuals interested in careers focused on conservation and natural resources management, this concentration develops an understanding of how human institutions and communities manage their relationships with ecological resources like forests, oceans, wildlife, soils, and more. Graduates with this concentration work as conservation planners, land-use planners, community development specialists, and park rangers.

Renewable Energy

The renewable energy concentration provides a broad understanding of the sustainable energies industry that, along with coursework in business economics and administration, prepares students for careers in alternative and renewable energy management. Renewable and alternative energy sources studied include solar, wind, nuclear, propane and natural gas, hydroelectric, geothermal, and biomass.

Accreditation for Online Environmental Science Degrees

Accreditation determined if colleges and universities meet important minimum standards of academic quality. It’s also a requirement for most financial aid resources, including all federal financial aid programs.

There are two types of postsecondary accreditation. Institutional accreditation concerns the quality of a postsecondary institution as a whole and is administered by several regional and national accrediting agencies recognized by the U.S. Department of Education. Programmatic accreditation refers to the vetting of specific degree programs.

There currently is no programmatic accreditation for bachelor’s degrees in environmental science, sustainability, or related majors. Therefore, always verify proper institutional accreditation of the school offering any environmental science degree program under consideration. Accreditation status is typically found on degree program or school accreditation webpages. You can also check a school’s status by visiting the websites of accrediting agencies.

FAQs About Online Environmental Science Degrees

How long does it take to earn a bachelor’s degree in environmental science online?

As with most bachelor’s degree programs, earning your online environmental science bachelor’s degree requires four years of full-time study.
