To protect the well-being of their communities and the planet, healthcare organizations must take the lead in correcting the negative impacts of their business on the environment by finding new ways to work cleaner and smarter. Stony Brook University Hospital has been recognized for making the commitment to develop and maintain sustainable practices-from the elimination of mercury to the efficient design of new facilities-that are good for the environment and good for business. With the participation of the entire organization, from the C-suites to the front lines, the results are measurably impressive.
