Sustainability and Wellbeing fills a gap in sustainable development. Sustainable wellbeing is achieved when improving individual wellbeing is correlated with improving the wellbeing of other members of society and the natural environment. Sustainability and wellbeing are two key global policy priorities, which despite considerable overlap, are invariably isolated. In wellbeing, the importance of social dimensions is an emergent conclusion, but recognition of the environment and nature is embryonic. In sustainability, wellbeing remains poorly characterized. Despite some procedural advantages, in practice, a continued ambiguity risks compromising both goals, and improved conceptual integration is therefore necessary.
