ABOUT US
A pioneer and leader in the social investment industry, Trillium Asset Management Corporation (”Trillium”) is the oldest and largest independent investment management firm in the U.S. exclusively devoted to sustainable and responsible investing. Since 1982, individual and institutional clients have chosen Trillium because of our emphasis on personalized service, an investment discipline providing consistent and competitive returns, and our deep commitment to advancing environmental sustainability, social justice and human rights through innovative investment, research, and advocacy.
We believe companies with strong social and environmental profiles are better managed for the long term, have lower risk profiles, and are positioned to outperform their peers. Our investment philosophy recognizes a mutually reinforcing, not mutually exclusive, relationship between competitive returns and promoting social and economic justice. We engage directly, through shareholder engagement and advocacy, and indirectly, through allocating capital to companies and sectors with positive economic, ecological, and social impact.
After nearly three decades of leadership in proactive, change-oriented social investment, we’re proud to stand on the cutting edge of a movement linking financial, social and environmental outcomes as sustainability concepts are embraced across the investment industry and around the world.

What is “trillium”?
The trillium symbolizes our social mission – weaving together the three elements of sustainability:
Ecology
or a healthy environment,
Equity
or social justice,
Economy
or healthy commerce.
