Welcome to the web site of the U.S. Center of the Stockholm Environment Institute, an international research organization working on sustainable development. SEI-US is a research affiliate of Tufts University in Massachusetts. Our main offices are on the Tufts campus in Somerville, MA and we also have offices in Davis, California and Seattle, Washington. more...

SEI's work is interdisciplinary in nature:
drawing upon engineering, economics, ecology, ethics,
operations research, international relations
and software design. We conduct applied
scientific research: bringing the best
available science to policy makers.
In addition to providing policy-relevant analyses, we build capacity in the developing world for integrated sustainability planning through training and collaboration on projects. Our decision support tools such as LEAP for energy and climate mitigation and WEAP for water resources are widely used.
Our activities are organized into three programs:
| The Climate and Energy Program conducts energy system analyses, examines environmental consequences of energy use such as global warming, and develops policies for a transition to efficient and renewable energy technology. | |
| The Water Resources Program brings an integrated framework to freshwater assessment, one that seeks sustainable water solutions by balancing the need for basic water services, development and the environment. | |
| The Future Sustainability Program takes a holistic perspective in assessing sustainability at global, regional, and national levels. |
The Stockholm Environment Institute US Center (SEI-US) is a non-profit research organization with 501c(3) status.
To learn more about our center and about our current projects, read our 2008 Center Report.
