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


JUNE 9: Congress did not act on legislation that could have rolled back changes to the shareholder proposal process that will make it harder to file and resubmit resolutions in 2022. The SEC has signaled increased interested in more mandated ESG disclosure, however, and the 2021 proxy season as of the end of May is witness to more majority votes than ever before, with 32 receiving more than 50 percent support.
