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


March 7: As of today, Si2 has identified 552 shareholder proposals on environmental and social policy issues filed for consideration at corporate annual meetings in 2023. We are well on the way to match or beat the 2022 record number of filings. Findings as of mid-February will be discussed in the Proxy Preview webinar on March 22. Si2 subscribers can see background papers, daily database updates, and reports on proposals going to votes in the Engagement Monitor.
