The Environmental Institute is the hub of environmental resilience and sustainability research at the University of Virginia.

The Institute seeks to foster collaboration, providing support for new projects as well as amplifying and connecting the work of others across disciplines at UVA. Faculty from fields including but not limited to architecture, urban planning, engineering, environmental science, the humanities, data science, business, and law are involved in projects to create workable solutions for climate change and environmental resilience challenges.
