环境科学与管理硕士（MESM）计划是为期两年的专业学位课程，专为计划毕业后进入或重新就业的人员设计。该计划侧重于应用程序和解决问题，分为三个部分：第一年核心课程，七个专业之一的第二年工作以及小组项目或生态创业项目。MESM学位不适合作为博士学位的中级学位，但是，MESM校友已为包括环境科学与管理在内的许多学科的博士学位研究做好充分准备。
Bren's Master of Environmental Science and Management (MESM) degree is a two-year professional program focused on preparing students for careers in environmental science and management through developing solutions to critical environmental problems. Students learn the fundamentals of environmental science and management in their core courses and later deepen their knowledge by choosing a specialization. MESM students also complete a master's project, either a group project or an eco-entrepreneurship (Eco-E) project. During the group project, students solve environmental problems for a real-world client, developing technical, leadership, and professional skills that advance their career potential. During the Eco-E project, students design a business model for a new, commercially viable product or service that will have a positive and measurable environmental impact. The MESM program prepares students to work in government agencies, corporations, nonprofit organizations, and consulting firms. Bren MESM graduates demonstrate clear and critical thinking, leadership skills, professionalism, and creativity that allow them to be leaders in solving the environmental problems of the 21st century.
