The Planetary Boundaries (PBs) describe an overall environmental analysis framework that reduces the functioning of the Earth system to nine control variables for which thresholds of anthropogenic pressure are set (Rockstrom et al, 2009). Environmental analysts have broadly relied on this global framework to establish local indicators of "absolute environmental sustainability" (AES), mostly using Life Cycle Assessment methods (LCA) (Bjørn, 2020).
Although these works renew the paradigm of environmental analysis, to our knowledge they have not yet focused on questioning the relevance of local environmental observation systems. If the majority of proposals for regional application of the PBs framework have a national scale, it is because most environmental aggregates are produced at this scale (see the synthesis by Li et al., 2021). But what if one wants to carry out an analysis on a territory of different scale where environmental policies might also be taken?
The proposal of this summary is to show that the Regionalized Planetary Boundaries framework can allow us to renew our approach to the physical, natural compounds of human systems by questioning the way environmental data is produced.
This point will be make through reading back RPBs-based indicators with the glasses of Quantification Sociology. We will unveil the equivalence normative (Desrosières, 2008) that lies behind the transition from theoretical indicators to practical indicators, by designing back again literature-based indicators on a territory (the inter-metropolitan area of Lyon-Saint-Etienne in France) and confronting them with local data.
This normative leads to defining a particular compromise in the relationship between social and ecological systems. We are assuming that it is possible, through working on the normative, to guide this compromise to a philosophy of strong sustainability. This assumption is formulated based on a participant field investigation with our territory's urban planners.
