About PSI


Policy Studies Institute (PSI) is committed to delivering insightful, high-quality research for our funders, users and wider society that has an impact on environment and sustainable development research, policy and practice.

We do this by working at the interface of policy and research. We combine the rigour of academic research with expert knowledge of policy agendas and processes. We generate research outputs collaboratively that meet the practical needs of policymakers. We aim to deliver results and outputs that are high quality, relevant, useable, and enrich the value of our users’ work.

PSI has informed public policy since 1931, through the provision, dissemination and promotion of high-quality, evidence-based research (read more about our history here). Now based in the Faculty of Architecture and the Built Environment at the University of Westminster, our interdisciplinary team applies a wide range of qualitative and quantitative methods and designs to produce research outputs intended to inform a sustainable future. The University is a holder of the HR Excellence in Research Award.

Our current areas of research include: energy and climate change; resource use and the circular economy; mobility and transport; the role of communities and business in delivering a sustainable future; cities, innovation and sustainability transitions; public behaviours, attitudes and policy; and policy and research evaluation.

Based in central London, we collaborate with an international network of researchers and centres working on environment and sustainable development policy, and we coordinate the Sustainable Development Research Network (SDRN).

PSI is politically neutral and has no connections to commercial interests or pressure groups. Our income is derived from a variety of sources including: government departments, research and higher education funding councils, the European Commission, charitable foundations and business.
