Stockholm Environment Institute at York

SEI is an international non-profit research and policy organisation that tackles environment and development challenges.

The Stockholm Environment Institute (SEI) is an independent, international research institute, which has specialised in environment and development research for over thirty years.  

The York centre sits within the Environment and Geography Department of the University of York. Our research is geared towards translating scientific evidence into information upon which sound policy can be developed and through which behaviour can be changed. 

SEI's overall mission is to support decision making and induce change towards sustainable development, by providing integrative knowledge that bridges science and policy. It has a strong action-oriented research profile, interacting closely with decision makers in the different projects it undertakes. It regularly advises governments and UN agencies at the highest levels.

Focus areas

The research of the SEI York centre is structured around four core focus areas, supported by cross-cutting activities that deliver research impact using different participatory research and stakeholder engagement methods. Our researchers – including our cohort of PhD students - work at international, national and local scales, with a presence both within the local and regional community and around the University of York, and in many high, middle and low-income countries.

Sustainable consumption and production

Exploring social and environmental impacts associated with economic activity and international trade, from local to global geographic scales.

Nature society relations

Focusing on particularly vulnerable sectors of society, we seek to improve understanding resilience in local communities across the UK, Europe and the rest of the World.

Air quality, climate and environmental change

Assessing impacts of air pollution under both current and future climate change conditions.

Environments, human health and wellbeing

Exploring the role of human-made or managed environments in influencing the physical and mental health of residents.

Cross-cutting research

Citizen science and other participatory research methods; stakeholder engagement and communication; and tools for sustainable development.

Stockholm Environment Institute is named after the Stockholm Declaration on the Human Environment, adopted at the UN Conference on the Human Environment in 1972. Our mandate, vision, approach and values are derived from the principles outlined in this declaration.
