Abstract
This study seeks to understand how underlying professional values may affect sustainable redevelopment outcomes. It considers the process by which a variety of professionals: engineers, scientists, designers, planners, architects and financial analysts, develop a professional norm of sustainability as they sustainably redevelop contaminated brownfield sites. Employees and associates of a private equity firm managing a portfolio of brownfield sites across North America and Western Europe were interviewed and resultant data were analyzed using grounded theory methodology. A framework for the professionalization of sustainability is proposed.
