The MIT Environmental Solutions Initiative (ESI) advances science, engineering, policy and social science, design, the humanities, and the arts towards a people-centric and planet-positive future. MIT launched ESI in 2014, a major campus-wide effort to coordinate and develop interdisciplinary solutions to urgent challenges in environment and sustainability. ESI aims to harness the MIT community’s ingenuity and the Institute’s unique culture of collaboration through diverse activities in research, education, and convening.
