Business and the Environment

Our Vision

The purpose of this specialization is to help YSE students who are interested in working on environmental issues in for-profit organizations, or in NGOs and public agencies that partner with for-profit organizations, be well prepared to do so. This specialization will be particularly helpful for MEM students with an environmental science or policy background and less experience with business concepts.
