Sustainvest Asset Management

Overview

Sustainvest Asset Management is a for-profit, left-of-center investment advisory firm that screens client portfolios using environmental, social, and governance (ESG) criteria and uses shareholder activism to pressure publicly traded businesses to adopt left-of-center environmentalist and social policies. ⁴

The firm’s targets have included Actavis, Dunkin’ Brands, Anthem, Dean Foods, Enphase Energy, and BioMarin Pharmaceuticals. ¹

As of the group’s March 2026 filing with the Securities and Exchange Commission, it reported $137,419,175 in assets under management across 360 accounts. ²

Founding and History

Sustainvest Asset Management began operations in 2013 as an independent, fee-only investment advisory firm in Petaluma, California, with Dale Wannen as its president and founder. The firm emphasized its left-of-center positions on environmental, social, and governance (ESG) issues with a strategy of promoting shareholder activism as a way to advance its positions. As of 2026, its clients included individuals, family foundations, and nonprofits, and the firm was based in Linwood, New Jersey. ^{4  5  3  6}

Sustainvest promotes the view that investors should use their capital, and their standings as shareholders, to push publicly traded businesses to change their environmental, social, and corporate governance practices towards more left-of-center positions. Wannen also advocated for divestment from fuel-energy holdings and steered clients away from large national banks. ^{4  5}

Projects and Initiatives

Shareholder Advocacy

As of June of 2026, shareholder advocacy was central to Sustainvest Asset Management’s public profile. The firm stated that it had filed shareholder resolutions to address corporate governance, climate change, political contributions, pesticide use, animal welfare, and pollution, and that it collaborated with activist organizations on those filings. ¹

The resolutions it listed included proposals asking Enphase Energy, Actavis, and BioMarin Pharmaceuticals to issue an environmental report; proposals at Dunkin’ Brands seeking the integration of environmental metrics into executive pay, a report on the environmental effects of the company’s single-serve K-Cup products, and the use of cage-free eggs in the supply chain; a proposal at Anthem to tie executive pay to environmental metrics; and a genetically modified organism (GMO) reporting proposal at Dean Foods. ¹

In 2014, Wannen secured a place on the proxy ballot of Actavis, an Irish pharmaceutical company valued at roughly $37 billion, for a proposal asking the company to issue a report on its environmental practices. The measure was supported by owners of nearly 45 million shares (about 32 percent of the votes tallied), and although it did not pass, observers in the shareholder-proposal field described the result as strong for a first-time filing. ⁷

Wannen repeatedly targeted Dunkin’ Brands, the parent company of the Dunkin’ Donuts chain, pressing it through shareholder proposals to adopt cage-free eggs and to discontinue its disposable single-serve coffee pods; as of 2017, both efforts had been unsuccessful. He said he viewed any shareholder proposal that reached a company’s proxy statement as a success because it raised the issue with all shareholders. ⁵

Environmental, Social, and Governance (ESG)

As of June 2026, the firm marketed environmental, social, and governance (ESG) screening as the core of its investment practice rather than an add-on service. It advised clients to evaluate where they banked and which funds they held, recommended index products such as the MSCI KLD 400 Social Index as alternatives to conventional benchmarks, and named businesses including Patagonia, Unilever, and Apple as companies it considered strong on environmental and social measures. ^{3  5}

Community and Impact Investing

Sustainvest offered what it called community investing, also described as impact investing, which directed a portion of client capital toward investments intended to produce social or environmental benefits alongside financial returns. The firm said clients could allocate from zero to roughly five percent of their portfolios to that category, and it pointed clients toward vehicles, such as the Calvert Foundation, notes that funded affordable housing and agricultural projects. ⁸

Leadership

Dale Wannen founded Sustainvest Asset Management in 2013 and worked as its owner and lead investment advisor as of 2026. He holds a bachelor’s degree in economics from Rowan University in Glassboro, New Jersey, and a master’s in sustainable management from the Presidio Graduate School in San Francisco. Before founding Sustainvest, he worked as a portfolio manager and director of shareholder advocacy at Harrington Investments, a self-described socially responsible investment firm known for filing shareholder proposals at publicly traded businesses. ^{4  5}

Wannen was active in left-of-center environmental and advocacy organizations. He was a board member and treasurer of Global Exchange, a left-of-center human rights and environmentalist advocacy organization based in San Francisco, and he was affiliated with the Natural Resources Defense Council, one of the largest environmentalist litigation and advocacy groups in the United States, as a San Francisco council member. He later was a board member of the nonprofit Stewards of the Coast and Redwoods and of the Sonoma County Community Foundation. ^{4  6}

Wannen wrote and spoke frequently on shareholder advocacy and authored a book titled Don’t Feed the Clowns: Sustainable Investing for Everyday Life. In shareholder-meeting appearances, he positioned himself as a small investor confronting large companies; he described his Actavis campaign as “Dale versus Goliath” and recounted telling Oracle chief executive Larry Ellison at a shareholder meeting that he was overcompensated. ^{6  5}
