The role of the CSO has changed significantly over the years, from a backroom marketing function to being key figures in their company’s business operation and growth. Roughly 183 public companies in the U.S. now employ a CSO, up from 29 in 2011, according to a recent report from recruiter Weinreb Group. Of those, more than three-quarters sit on the company’s leadership team while just over a third report directly to the CEO. With this elevated status comes increasing responsibility for CSOs to be the chief communicator of a company's social and environmental efforts — both internally and externally. Yet with many CSOs coming from technical backgrounds, they aren’t always prepared to be the person behind the podium. In this episode, Mike connects with Ellen Weinreb, one of the world’s leading sustainability recruiters who has worked with countless CSOs over the years, to better understand the ever-evolving role of the CSO and what this means for sustainability communication.
