Who puts this event on?

Plain Green Conference and Marketplace is hosted by the Sioux Falls Green Project, in partnership with the conference founders, South Dakota State University and Koch Hazard Architects. It is made possible by our sponsors and a small army of volunteers (we call them the “Moxie Squad”).

Who attends Plain Green?

Plain Green is a gathering place for sustainability game-changers in the Northern Plains. Many of our attendees are educators, students, design professionals (architects, engineers, landscape architects, interior designers, etc), developers and planners.
