Clean Yield Asset Management

Clean Yield Asset Management

Clean Yield Asset Management was founded as one of the earliest investment firms dedicated to social and environmental screens. Principals Bob Logue and Vicki L. Billington lead a team that advises institutions and families on fossil-fuel-free portfolios. The firm emerged from the community investing movement in the United States (public record). Strategy spans public equities, fixed income, private credit, and direct investments. The firm targets clean energy, sustainable agriculture, and affordable housing. Portfolio construction uses negative screens (fossil fuels, tobacco, weapons) and positive screens (renewable energy, fair labor). Co-investments have included community loan funds and renewable energy projects across the United States and Canada (public record). Team size and AUM are not publicly disclosed. The firm operates from New Hampshire and has not published recent changes in leadership or new fund launches. No known philanthropic vehicle or adjacent operating company is documented in public sources. The firm's structural distinction is its focus on fossil-fuel-free portfolios for institutions and families — a younger approach than ESG integration but older than the impact-investing boom. Its small size and regional footprint limit deal flow to smaller direct investments and fund commitments.
