From 27 to 29 October 2005, 35 experts in higher education for sustainability (HES) representing 17 countries, gathered in Halifax, Nova Scotia. This consultation represents the first gathering of HES researchers in Canada, and brought Canadian and international researchers together to further intellectual understanding of HES research and to explore the development of research priorities for the future. The Delphi Technique was used at this workshop in order to aid in the development of a preliminary research strategy for HES research. The Delphi exercise was the primary focus of the workshop. This report summarises both the workshop information and results. (Contains 1 table, 1 figure, and 2 notes.)
