The Sustainable Investments Institute (Si2) is a non-profit organization based in Washington, D.C. We conduct impartial research and publish reports on organized efforts to influence corporate behavior on social and environmental issues.

Si2 closely follows shareholder resolutions proposed by investor activists, analyzing changing reform campaigns and identifying key points of contention in reports that help investors to make informed, independent decisions about their votes and views on these proposals. We also publish related reports for the public on selected topics.

We believe our robust, non-partisan analysis of corporate sustainability concerns informs investor, company and stakeholder dialogues, helping to identify better solutions. Working as an independent institute differentiates Si2 from other companies, activists and researchers in the field. We do not advocate for specific solutions but seek to build a body of agreed knowledge for smart policy-making.


News & Votes


JANUARY 5: When the dust settled on the extraordinary 2022 proxy season, proponents had filed 631 shareholder resolutions seeking more disclosure and policy changes on social and environmental topics. Never before had investors voted on 310 such proposals, but they did in 2022, even as proponents withdrew at least 268 proposals (mostly after companies agreed to act), and just 39 proposals were omitted after company challenges under SEC rules. A handful of resolutions did not go to votes for other reasons.


The 2023 proxy season will bring new ideas, with many already facing company objections in challenged lodged at the SEC.
