The Quest for Ecological Sustainability: A Multi-level Issue

The issue of ecological sustainability has been addressed in various contexts - local, regional and world-wide. This paper postulates that sustainability can only be achieved if actors at multiple levels cooperate toward the vision of a sustainable world. For this purpose, the structure of a model is presented, which shows how the efforts for sustainability can be organized in a more powerful way. This presentation should also help decision-makers understand that pertinent frameworks are needed to enable actors at each level, from individual to global.
