About SEI US

SEI-US is a non-profit research organization with 501c(3) status in the United States and is a research affiliate of Tufts University in Massachusetts. The main office is on the Tufts campus in Somerville, MA along with smaller offices in Davis, California and Seattle, Washington.
The SEI US centre's work is interdisciplinary in nature: drawing upon engineering, economics, ecology, ethics, operations research, international relations and software design. It conducts applied scientific research: bringing the best available science to policy makers.
In addition to providing policy-relevant analyses, the centre builds capacity in the developing world for integrated sustainability planning through training and collaboration on projects. The centre’s decision support tools are widely used such as LEAP for energy and climate mitigation and WEAP for water resources.
For an overview of our current projects and publications, read our 2008 US Center Report.
