This ambitious project addresses the very core of Sustainable Development (SD) as popularized by the Brundtland Commission and politically enshrined in the Sustainable Development Goals (SDGs) and which has been the explicit focus of sustainability science. It directly addresses the “ultimate end” (in the terminology of Donella Meadows) of SD by developing a tailor-made wellbeing indicator that can be used as sustainability criterion.
In sustainability science there is broad agreement that the trend of human wellbeing (W) over time should serve as sustainability criterion. It often centers around an equation in which W is determined as a function of a set of capitals (natural, human, economic) as well as knowledge and institutions. The literature so far has mostly addressed this function in terms of the determinants of wellbeing and the change over time in the different capitals contributing to “inclusive wealth” rather than focusing on the trends in W itself. This ERC project addresses W itself by developing an indicator of W that can be assessed in its trend over time for different populations (sub-populations) of interest.
There is broad agreement that an indicator for W should have multiple constituents, clearly going beyond GDP. However, the research community is divided into some that the prefer to focus exclusively on objective indicators based on empirically observed data (such as the Human Development Index) and others that think that only subjective assessments (such as happiness and life satisfaction scores) provide valid measures about how people themselves rate their wellbeing. The wellbeing indicator developed under this project tries to incorporate both the subjective and objective dimension of wellbeing. It is a tailor-made indicator following the specification of seven explicit desiderata that should be met (see specification below). The indicator, Years of Good Life (YoGL), is also based on the evident fact that in order to be able to enjoy any quality of life, one has to be alive. But since mere survival is not considered as good enough, life years are counted conditional on meeting minimum standards on the objective dimension of capable longevity (being out of absolute poverty and enjoying minimal levels of physical and cognitive health) and the subjective dimension of life satisfaction. In the first part of the project, we dealt with the definition and operationalization of the criteria, with data requirements, inter-temporal dynamics, and provided illustrations for (sub-) populations at different stages of development. In the following steps the inter-cultural acceptability of the indicator and its determinants have been addressed.
