About the company
Stockholm Environment Institute U.S., Inc., a tax-exempt nonprofit research organization based in Somerville, Massachusetts, receives federal grants for environmental science and sustainability research as a prime recipient, and provides technical assistance to international development programs as a subcontractor to for-profit implementers. The vendor operates primarily as a grant recipient (76% of recent awards), with a much smaller subcontract footprint.
SEI U.S. serves nine distinct federal agencies across a research and technical-assistance portfolio. By award count, the top customers are the Department of the Interior Bureau of Reclamation (3 awards, $316 thousand combined potential value), the U.S. Agency for International Development (3 awards), USAID Central Asia Kazakhstan (3 awards), and the National Aeronautics and Space Administration Shared Services Center (3 awards, $81 thousand combined potential value); these four entities account for 67% of recent awards. By potential dollar value, the Interior Bureau of Reclamation leads at $316 thousand, followed by NASA SSC at $81 thousand. The vendor also has active relationships with the Department of Commerce National Oceanic and Atmospheric Administration and the Department of the Army Corps of Engineers National Capitol Region Humphreys Engineer Center Support Activity. Recent grant work includes a $317,156 award from NASA SSC (July 1, 2026, through December 31, 2028) to execute a balanced science program under CFDA 43.001 (Science), and a $80,684.55 grant from NASA (October 1, 2022, through March 29, 2024) for a landscape analysis integrating satellite-based remote sensing and indigenous knowledge in California land management.
In its subcontractor role, SEI U.S. delivers technical assistance to Tetra Tech on the Urban Resilient Water Security, Sanitation, and Hygiene (URWASH) program (awards December 8, 2021, and March 25, 2022, carrying $2.16 million in incremental funding), and to Ard, Inc. on the USAID Regional Water and Vulnerable Environment Activity (WAVE project) (award December 23, 2022). The vendor's work centers on water security, resilience, and sustainable development research and technical assistance, with particular focus on international development contexts. Award activity has been episodic — averaging fewer than one award per year across a fifteen-year span — and remains small in scale; combined potential value across all twenty-one awards is $739 thousand, though combined obligations of $6.4 million reflect that many awards carry multi-year performance and cumulative funding above their stated ceilings. The vendor sits on one named parent vehicle: One Acquisition Solution for Integrated Services (2 task orders).
