Getting started

Many questions have surfaced in recent years regarding sustainable and ESG investing.  Here, investors and financial intermediaries will find materials that describe the various approaches to sustainable investing and their implementation.  While sustainable investing approaches vary and they have thus far defied universally accepted definitions, many practitioners agree that they fall into the following broad categories:  Values-based investing, investing via exclusions, impact investing, thematic investments and ESG integration.  In conjunction with each of these approaches, investors may also adopt various issuer engagement procedures and proxy voting practices.  That said, sustainable investing approaches will continue to evolve.

In addition to periodic updates regarding sustainable investing and how this form of investing is evolving, investors and financial intermediaries interested in implementing a sustainable investing approach will also find source materials that cover basic investing themes as well as asset allocation tactics.
