Research Repository
This collection brings together work based on the Millennium Institute's models: the iSD model and its predecessor, Threshold 21 (T21). It includes reports and papers by the Millennium Institute and its partners, as well as research by universities, institutions and independent researchers who have applied these models in their own work.
The collection spans three decades of work, from the first T21 applications in the 1990s to current analyses of the Sustainable Development Goals, climate policy and green transitions in more than 40 countries. Use the filters to browse by type, country or region, focus area and year.
