Feasta aims to identify the characteristics (economic, cultural and environmental) of a truly sustainable society, articulate how the necessary transition can be effected and promote the implementation of the measures required for this purpose.

Feasta believe that sustainability must benefit everyone in a society, rather than merely those who are financially or otherwise privileged. They consider a society to be sustainable if it can expect to survive for several hundreds of years without being forced to change because it is currently destroying or undermining something on which its survival crucially depends.
