With an estimated two-thirds of the Earth’s population living in cities by 2050, Kahlil Kettering works for urban development and natural infrastructure that benefits both ecosystems and human residents. With The Nature Conservancy, Kahlil is leading efforts in Washington, D.C. that have created the first Stormwater Retention Credit market in the world, which requires development projects to retain most of the stormwater it generates from impervious surfaces. Kahlil manages all aspects of this program, raising money for projects and selecting design and construction contractors to ensure maximum environmental benefit and return on investment. Previously, Kahlil worked as strategic consultant for Water Reuse Association in Alexandria, Virginia, and as the Biscayne Restoration Program Analyst for National Parks Conservation Association in Hollywood, Florida, which protected sensitive lands around Everglades National Park. He holds a master’s degree in public management from University of Maryland, and a master’s in global environmental policy and a bachelor’s degree in international studies from American University.
