Sarah K. Mack, MSPH, PhD, CFM
President and CEO of Tierra Resources
Sarah K. Mack, PhD, is President and CEO of Tierra Resources and is an acknowledged leader in the movement to monetize wetland carbon offsets. In her work, Dr. Mack focuses on innovative approaches to address the global challenges of climate mitigation, urbanization, and pollution through wetland and water management. Dr. Mack led the development and was the lead author of the American Carbon Registry Methodology, Restoration of Degraded Deltaic Wetlands of the Mississippi Delta, the first certified methodology for creating and monetizing carbon offset credits from wetland restoration activities. Dr. Mack leads the implementation of the first wetland carbon pilot projects in the nation that include a freshwater cypress pilot project in partnership with Entergy Corporation, and a mangrove pilot project in partnership with ConocoPhillips. Dr. Mack directs overall activities and works alongside state, municipal, and private partners to generate marketable eco-assets.
Previously Dr. Mack was the Technical Administrator of the Sewerage and Water Board of New Orleans (S&WB) where she also served during Hurricane Katrina as the Emergency Liaison between the S&WB and other agencies responsible for the initial response and later recovery of sewer, water, and drainage infrastructure.
She received her PhD in Global Sustainable Resource Management from Tulane University and is an ASFPM Certified Floodplain Manager.
