This paper focuses on a Sustainable Portfolio Management (SPM) approach that Solvay developed to support decision making and inform strategic direction. The tool is integrated into the Solvay Way Framework and serves as a vehicle to measure the maturity of sustainable business practices. Since its development in 2009, the SPM profile has been integral part of the strategic discussions of each of the group’s Global Business Units (GBU’s) with the Executive Committee. Investment decisions (Capex or M&A) taken by the Executive Committee or the Board of Directors are also informed by the use of this tool. The results have been very encouraging and Solvay is now ready to open up the methodology as an open source tool for others to use.
