Earth Systems

The Earth Systems Program is the premier undergraduate and coterminal degree-granting interdisciplinary program within the Stanford Doerr School of Sustainability. Established in 1992, Earth Systems functions as a major academic division of the school, founded on the principle that solving complex environmental challenges requires a holistic understanding of the Earth as an integrated system of coupled human and natural components.

The program bridges the gap between scientific discovery and real-world implementation, training students to apply interdisciplinary systems thinking to address the climate crisis, biodiversity loss, and resource depletion. Over its 34-year history, Earth Systems has cultivated a collaborative, student-centric community where undergraduates receive the rigorous scientific foundation, analytical tools, and communication skills needed for careers leading the transition toward a sustainable and just future.

Academic Programs and Pathways

The Earth Systems curriculum offers both exceptional breadth across the fundamental sciences and targeted, deep expertise in a chosen field. Students build a strong foundation in chemistry, physics, biology, geology, calculus, and statistics, while concurrently studying economics,environmental policy, and environmental justice.

Bachelor of Science (B.S.) in Earth Systems: Undergraduates specialize in their upper-class years by selecting one of eight interdisciplinary tracks:

• Biosphere: Focuses on the complex interactions between biological systems and the physical Earth. Students study ecology, evolutionary biology, conservation, biogeochemical cycles, and ecosystem services to understand how human activities affect biodiversity, habitats, and ecological health.

• Energy Science and Technology: Examines the engineering, physics, and deployment of clean energy systems. Students analyze renewable energy technologies (such as solar, wind, and geothermal), energy efficiency, grid integration, and the policy and technological innovations required to transition away from fossil fuels.

• Human Environmental Systems: Explores the economic frameworks, market designs, and political systems shaping environmental governance and sustainable development. Students learn to evaluate environmental laws, design market-based conservation strategies (like carbon pricing), and analyze the political dynamics of local, national, and international environmental policy.

• Land Systems: Investigates the processes driving land-use change, urbanization, and human-environment interactions on the Earth's surface. This track emphasizes spatial analysis, geography, remote sensing, and geographic information systems (GIS) to study deforestation, habitat fragmentation, sustainable land management, and urban planning.

• Sustainable Food and Agriculture: Focuses on the ecological, economic, and social dimensions of global food security. Students explore sustainable agricultural practices, soil health, water management, agronomy, and food supply chains to design food production systems that minimize environmental impacts while feeding a growing global population.

• Oceans, Atmosphere and Climate: Explores the physical, chemical, and biological processes of the oceans and atmosphere. Students investigate ocean currents, marine ecosystems and conservation, biogeochemical oceanography, climate dynamics, and global climate models to understand the oceans' critical role in regulating Earth’s climate and responding to global warming.

• Environmental Geoscience: Apply understanding of the geological processes that shape Earth’s surface and regulate its habitability, together with knowledge of social-environmental systems, to identify strategies for addressing natural hazards and resource challenges in ways that benefit society. 

• Sustainable Societies & Environment: Explores the social sciences, data science, and governance models to identify levers for social change, predict human behavior in the face of environmental challenges, and develop strategies to motivate people and the organizations they create to build a more just and sustainable society.

Minors: Students majoring in other fields can enrich their degree with an Earth Systems minor, choosing a subplan in either Sustainability or Environmental Justice.

Coterminal Master’s Program: Qualified undergraduates can seamlessly transition into a coterminal Master of Science (M.S.) or Master of Arts (M.A.) degree, allowing for advanced research, data analysis, or policy formulation

Distinctive Program Features

• Hands-On Professional Internships: A cornerstone of the Earth Systems major is the required 270-hour supervised internship. This experience provides students with practical, real-world experience working in research laboratories, field stations, clean-tech startups, government agencies (such as NOAA or the EPA), or international environmental NGOs.

• Practical Skill Development: Beyond theoretical knowledge, the program equips students with highly marketable, practical career skills, including geographic information systems (GIS) and spatial modeling, environmental data analysis, policy writing, and effective science communication.

• A Supportive, Interdisciplinary Network: Because Earth Systems is inherently interdisciplinary, its advising and teaching network draws on faculty from all seven schools across Stanford. This is complemented by a peer advising system and a global alumni network that actively mentors and recruits graduates into a diversity of careers, including engineering, consulting, policymaking, education, and conservation.
