About COSI

An applied research think tank catalyzing implementation of sustainable, resilient public infrastructure.

Our Mission

COSI, the Center for Optimized and Sustainable Infrastructure, is a 501(c)(3) nonprofit formed in 2025 to catalyze cost-effective, sustainable infrastructure that promotes environmental, climate, societal, and economic resilience. Through international partnerships and innovative technologies, COSI fills data gaps, linking threats to measurable, implementable outcomes that yield a holistic range of public benefits.

COSI’s focus lies in the built environment, inseparably linked to the natural environment. Methods to build and rebuild effective infrastructure, through definable metrics, funding, financing, procurement, and processes, will be tested and established at a level of detail that enables and spurs action.
