New Websites!June 2009: www.co2offsetresearch.orgThe website provides an up-to-date analysis and synthesis of the most influential offset programs and activities. It reflects on lessons learned, and aims to inform consumers as well as participants and designers of current and future offset programs. Policy Information - provides in-depth analysis and information about offset design and policies. April 2009: www.RealClimateEconomics.orgSEI senior researcher Frank Ackerman played a leading role in developing a new website launched by Economics for Equity and the Environment Network (E3, www.RealClimateEconomics.org, to demonstrate the weight of economic analysis in the peer reviewed literature that supports immediate, large-scale policy responses to the climate crisis. |
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.
Our 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.

June 2009, SEI Discussion Paper
Anja Kollmuss and Allison Myers Crimmins
The second of two papers that examine the key factors that have to be taken into account when calculating air travel emissions for the purpose of climate footprint and offset calculations. The paper is written for a non-technical audience and explains how to account for non-CO2 impacts of air travel emissions.

Liz Stanton and Frank Ackerman are co-authors, along with Kristen Sheeran, Director of Economics for Equity and the Environment (E3 Network), of a report on interstate differences in per capita GHGs.
It explains why some states have much lower emissions than others and helps clarify the potential regional impacts of policies, such as cap-and-trade, which will impose a price on energy-related carbon dioxide emissions. More...
April 28 & 29, 2009
SEI co-sponsored the Biological Sequestration through GHG Offsets: Identifying the Challenges and Evaluating Potential Solutions workshop organized by the World Resource Institute. The workshop convened technical representatives of key U.S. and Canadian federal agencies, RGG), WCI, MGGRA, and the Province of Alberta together. Michael Lazarus presented on Offset Supply Potential: Uncertainties and Implications
