About Boston Common Asset Management LLC

Boston Common Asset Management is an experienced investment manager dedicated to the pursuit of financial return and social impact; Boston Common incorporates environmental, social, and governance (ESG) factors into every stage of the investment research process. Through the visionary leadership of founder Geeta Aiyer, the firm pioneered the expansion of ESG into the global space. Boston Common’s founding colleagues have worked together since the mid-1990s and key members of the Investment team have steered the firm since its inception.

In Boston Common’s view, understanding ESG factors is crucial to valuing a company; the firm analyzes investment risks and opportunities from a broader perspective. It seeks competitive investment returns from portfolios of companies that can contribute to and benefit from sustainable, global growth. Additionally, Boston Common actively engages companies on issues that we believe will accomplish the dual task of improving financial fundamentals and promoting leaders on the environment and human rights.

Boston Common has extensive experience serving pension funds, endowments, foundations, mission-driven organizations, religious groups, and families across the United States. Its clients share a common conviction in sustainable enterprise and a commitment to ethical standards. They invest with Boston Common to align their missions with their investments. Boston Common is a women-led and employee owned firm with headquarters in Boston and an office in San Francisco.

As investors that seek to improve corporate practices, we believe it is also important to “walk our talk” in our own day-to-day behavior. It was natural for us to join the B Corp community and support the movement of like-minded companies that are committed to using business as a force for good.

The Change We Seek®

Boston Common integrates financial and sustainability factors into its investment process because ESG research helps identify companies that will be successful over the long-term. Boston Common seeks companies that can capitalize on new market opportunities, implement efficiency improvements, and avoid unanticipated costs stemming from inadequate attention to ESG risks. Additionally, Boston Common uses its voice as shareowners to improve corporate and industry practices globally and to advance the global dialogue toward a sustainable economy. The firm’s engagement strategy as long-term, global investors builds on its investment themes of doing more with fewer resources, treating people as assets, and supporting better governance. Investors with a deep and long-term understanding of prosperity can use ESG analysis and direct engagement to provide the critical checks and balances that financial markets require to function as efficient and socially beneficial distributors of capital.
