About SSF

With the objective of stimulating and assisting societies in their development towards sustainability, the Sustainable Society Foundation – SSF – has been established in 2006 as a private initiative by Geurt van de Kerk and Arthur Manuel. The main objective remains to further develop the Sustainable Society Index – SSI – and to publish and disseminate the results every two years. The SSI has been developed for 151 countries on national level. Nowadays the SSI has been implemented on regional level as well. We are working on the development of the SSI on local level.

Furthermore, SSF is involved in various fields of promoting sustainability: development and implementation of projects aiming at development towards sustainability, research projects, lectures and contribution to sustainability courses and support of students.

The SSF has an extensive world-wide network of experts who support and contribute to the work of SSF, as well with respect to methodological aspects as to the various elements of sustainability.
