The Stockholm Environment Institute (SEI) is an independent, international research institute specializing in sustainable development and environment issues. It works at local, national, regional and global policy levels. The SEI research programs aim to clarify the requirements, strategies and policies for a transition to sustainability. These goals are linked to the principles advocated in Agenda 21 and the Conventions such as Climate Change, Ozone Layer Protection and Biological Diversity. SEI along with its predecessor, the Beijer Institute, have been engaged in major environment and development issues for a quarter of a century. It seeks to be a leader in the creation of a new field of sustainability science aimed at understanding the fundamental character of interaction between nature and society, and to contribute to the capacities of different societies to build transitions to more sustainable futures.
SEI has research centers in Sweden, Estonia, the United Kingdom, the United States and Thailand. Each of these centers brings a commitment to integrated analyses of complex problems, drawing upon the full range of scientific and policy expertise across the SEI centers. Each center has its own personality and foci of interests, and each operates with significant autonomy while participating in the five cross-cutting SEI research programs. Each center shares a common commitment to policy-relevant research, and to the goal that SEI should make a difference in the global quest for a more equitable and sustainable planet.
SEI research programs include Atmospheric Environment, Climate and Energy, Future Sustainability, Policy and Institutions, Risk, Livelihoods and Vulnerability, and Water Resources and Sanitation.
