This final chapter assesses the feasibility of the ideas proposed in this book. It concludes that many parts of the project are feasible because the scientific knowledge exists and in many cases databases have already been produced. Also, the split into system and quality accounts allows for structured multidisciplinarity to be implemented. A practical problem is organisation and implementation of this programme.

The previous chapters have shown that there is one powerful community (“the GDP multinational") which is being challenged by a heterogeneous and weakly organised community (“the Beyond-GDP cottage industry). The ever-expanding range of Beyond-GDP initiatives will not lead to success however. A new strategy is based on the GDP success story and aims to create an institutionalised community with a clear goal and coherent structure based on a common language. The chapter argues that the community should not be based on the SDGs, green accounting or the SEEA. It also argues that the community should not be based on economic terminology and theory but rather on multidisciplinary building blocks such as stock/flow accounting, networks and limits. The aim of the community is to enhance well-being and sustainability and one of its most important features is its common language: the System of Global and National Accounts (SGNA). The SGNA has four system accounts (environment, society, economy and distribution), which describe how the systems are developing. However, this does not yet tell people whether the developments are good or bad. This is left to the quality accounts.
