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.

JUNE 24: Shareholder proponents filed suit against the SEC on June 15 in an effort to nullify a September 2020 change that will make it harder to file and refile shareholder proposals starting in 2022.

Separately, Si2 issued a press release today with highlights from the spring proxy season noting the 34 proposals which have earned majority support.
