    Program Overview

    The Master of Environmental Management curriculum draws from coursework in the natural and social sciences and focuses on the complex relationships among science, management, and policy. The purpose of the program is to provide students with an in-depth understanding of natural and social systems that can be applied to environmental and natural resource problem solving in a policy or management context. In addition to course work, students are expected to hone their capacities as leaders and managers through summer internships, professional skills courses, and other opportunities.

    The MEM curriculum requires students to focus on an area of specialization, while still offering the flexibility to tailor their course programming in a way that exposes them to other disciplines and subject areas. This structure assures that students develop both depth and breadth in their course of study. Students can choose from more than 100 courses offered by YSE faculty and have access to an even larger number of courses from across Yale University.

    MEM Goals

    • Provide the broad knowledge necessary to engage in 21st environmental challenges while gaining the depth required to offer expertise
    • Expose students to diverse perspectives and approaches to environmental problem-solving
    • Offer clear pathways for subject immersion through required specializations while encouraging exploration
    • Foster interdisciplinary teamwork focused on developing and validating solutions to environmental challenges
    • Equip students with practical, professional skills needed to be effective organizational leaders
    • Support student learning, training, and engagement through robust learning communities

    MEM Curriculum Details

    MEM Specializations

    All MEM students are required to choose one specialization.
    Specialization are designed to ensure that students obtain sufficient depth in their chosen area of study. Specialization requirements account for 18 of the 48 total credits required for the MEM degree, and it is possible to add a second specialization. Students have until the end of their second semester of study to choose their specialization, which will be listed on their transcript, upon completion.

    Student and Alumni Impacts

    Waste Warrior

    As founding chair of the New York City Public Housing Authority Recycling Committee, DeNeile Cooper ’22 MEM is working to help boost recycling efforts in public housing units.

    Only 2% of waste from NYCHA units is recycled. Nationally, that rate is 32%.

    “This work has been successful so far because it involves a variety of stakeholders who bring their unique perspectives to create programs that work for everyone,” says Cooper, who is a member of the Manhattan Solid Waste Advisory Board.

    Generating Climate Solutions

    While tackling the climate crisis can seem overwhelming at times, Victoria Mansfield ’22 MEM is helping to find answers by overseeing the Climate Solutions Generator, a six-week program run by Yale’s Center for Business and the Environment and the Tsai Center for Innovative Thinking.

    More than 50 students participated in the program in teams, pitching a solution on issues ranging from food waste to energy.

    “It is motivating to work with teams of students with interdisciplinary backgrounds who are coming together for innovate solutions,” says Mansfield.

    Tree Equity

    Using income, age, ethnicity, health, and surface temperature data and tree canopy surveys, Ian Leahy ’21 MEM, vice president of urban forestry at American Forests, helped create a Tree Equity Score. Wealthy urban communities, it found, have 65% more tree cover than low-income neighborhoods where temps can range 10 degrees higher.

    The issue is a matter of health, Leahy noted in a NYT Op-Ed., and his efforts have led to more financial support for urban tree growth.

    “What we're trying to do right now,’’ he says, “is close the canopy gap to save lives.’’

    Working to Make the Midwest Greener and Cleaner

    As the climate solutions director at Clean Wisconsin, a nonprofit whose mission is to fight for clean air and water in the state, Chelsea Chandler ’10 MEM is working to protect one of Wisconsin’s most effective programs: Focus on Energy, the statewide energy efficiency program.

    By helping people buy efficient lightbulbs or tune up their grain dryers, Focus on Energy has been an enormous success, and Chandler says that evaluations of the program have consistently shown huge returns for the investments.

    Re-imagining Urban Tree Life

    Cambium Carbon, a startup company founded by classmates Ben Christensen ’20 MEM and Marisa Repka ’20 MEM, is re-imagining the urban tree lifecycle — and helping combat climate change in the process.

    The company is building “reforestation hubs,” a unique private-public partnership that restores city forests across the U.S. Cambium Carbon received its initial funding from the Center for Business and the Environment at Yale and the Tsai Center for Innovative Thinking at Yale. It has now launched pilot reforestation hubs in four U.S. cities in 2021: Denver, Pittsburgh, New York City, and Eugene, Oregon.

    Preserving and Restoring Urban Forests

    Sarah Charlop-Powers ’09 MEM is helping to preserve and restore critical urban forests in New York City and beyond. In 2012, she helped launch the Natural Areas Conservancy (NAC), which has partnered with NYC Parks to create the innovative Forest Management Framework that conducted field-based ecological assessments in the city. Its efforts recently expanded with a national survey distributed to 125 cities and organizations across the U.S. aimed at gaining a better understanding of how urban forests and natural areas are being managed.

    Caroline Ebinger ’22 MEM/MBA is promoting an earth-friendly lifestyle through a startup company, Mesa Foods, that sells spice mixes for backpacking meals.

    Working the concept through Yale’s Tsai Center for Innovative Thinking, Ebinger, in partnership with Tony Cisneros ’21 MEM/MBA, received startup funding and the Center for Business and the Environment.

    The company supports sustainable farmers and food suppliers who are practicing planetary health principles.

    “I really have always believed that for-profits can be a tool for social environmental impact,’’ Ebinger says.

    Keeping Bhutan Carbon Neutral

    To make good on its constitutional mandate to be the first carbon neutral country for its entire existence, Bhutan relies heavily on its forest cover.

    Dechen Dorji ’01 MEM led the Bhutan for Life initiative, which raised more than $40 million to finance the protection of the country’s pristine network of protected areas.

    Dorji continues to work on land preservation and protection of endangered species as the World Wildlife Fund’s senior director for the Asian Wildlife Program.
