Social sustainability emerges from ideas about good corporate citizenship and social responsibility. When used in conjunction with triple bottom line frameworks, the term implies that humans matter at least as much as economics and the environment. It is concerned with the durability and function at 3 levels: the broad scale of social networks, the more intimate level of relationships, and the individual quantum of well-being. All 3 of these levels feed into the productivity mix. Moreover, a major implication of sustainability is that a balance of these 3 dimensions will result in more durable productivity than incongruent levels.
