Justin Freiberg is the Managing Director at the Carbon Containment Lab, envisioning, designing, and deploying scaled climate solutions––a continuation of his work since spinning the lab out of Yale University. His work targets carbon removal and emissions reduction, encompassing both natural and engineered systems, but remains focused on the needed human, community, and economic considerations that will lead to large-scale implementation.

Justin is an expert in building unique and long-lasting collaborations with diverse stakeholders around shared interests in the natural environment. While at Yale, he founded and directed the Yale Landscape Lab, which utilized the entire Yale West Campus, creating new venues for game-changing applied research and entrepreneurship. He co-founded and directed Yale Cultivate Health, building new ways to teach within the health sciences using ecological knowledge to change patient habits, and serves as a mentor in residence at Yale's Tsai Center for Innovative Thinking.

Previously, Justin co-founded Encendia Biochar and the Urban Foodshed Collaborative, both of which aimed to close material and social loops to create resilient, sustainable systems. He's worked with the Wildlife Conservation Society, Added Value, the University of Liberal Arts Bangladesh, the US-Asia Institute, and Stone Barns Center for Food and Agriculture. He's also apprenticed under farmers in Italy, France, and the US and has advised startups focusing on food systems, land use, and sustainability.

Justin holds an MS from the Yale School of the Environment, an MA and BA in Psychology from Wesleyan University, and a Certificate in Conservation Biology from Columbia University.
