“The Council of Institutional Investors is an effective and impactful organization that advances governance standards on behalf of its members, and I am honored to serve on the board,” Mastagni said. “Our mission in SISS is to be a catalyst in transforming financial markets to focus on long-term value creation that fully integrates sustainability considerations, which is perfectly aligned with CII.”
