SEI’s Executive Director, Måns Nilsson, leads and delegates the work of SEI.

Origins of SEI
SEI was set up by the Swedish government in 1989 to act as an international institute in the field of environment and development. Its activities build upon the insights gained at the UN conference on environment and development in Stockholm in 1972, which emphasised the impossibility of separating environmental concerns from development.
When SEI was set up, it asked the then Director of the Beijer Institute in Stockholm to become the first SEI Executive Director. The work of the Beijer Institute was a foundation upon which the initial development of SEI was built, and one centre of the Beijer Institute had been set up by Professor Mike Chadwick, who had been an academic in the Department of Biology from early in the University’s history. Together with another centre in Boston in the US, the York Centre, under the Direction of Mike Chadwick, became one of the founding centres with Stockholm.
SEI Centres
SEI works from seven main locations, with additional offices linked to these. The SEI foundation in Sweden consists of SEI Headquarters in Stockholm, SEI Asia, SEI Africa, SEI Latin America and SEI Oxford. SEI Tallinn, SEI US (with office in Boston, California and Seattle) and SEI York are separate entities and associations under the SEI umbrella and governed by the same Board of Directors.
