Overcoming the current development model, universally deemed unsustainable, requires, in the various Territorial Systems, the implementation of a strategy based on four components which are closely interconnected: Supporting sectors (research, training and communication); Business production and investment models; Household consumption and savings models and No profit Institutions decision-making models.
Strategy which, based on policies acting symmetrically on the four components mentioned above, is capable of guiding and supporting the Society towards a growing balance between intra-generational and inter-generational equity. In the present paper, the authors have highlighted the centrality of the Territorial Capital for the achievement of a Sustainable Wellbeing; analyzed the path towards Agenda 2030, which has finally codified this centrality; presented a Circular Economic Model proposed to analyze the determinants of "circularity" of Well-being.
Finally, the criteria are defined for an impact analysis of the new policies that are emerging at international, european and national level for building a sustainable future.
Keywords: territorial capital, well-being sustainability, Circularity, Agenda 2030, Policies for Sustainability, intra-generational equity and inter-generational equity.
