Quels indicateurs pour suivre et animer un PCAET ? Retour d’expérience d’un projet Européen

The territorialisation of climate action is embodied in the Territorial Climate-Air-Energy Plans (PCAETs), which are developed and piloted by local authorities. An increasing amount of data is being made available to support them in this endeavour. Local authorities are experimenting with using this data to produce new, more recent, frequent or detailed indicators. This may seem surprising given that many indicator systems are already available to them. Here, we report on the needs identified during five years of experimentation by a research consortium based in the Dijon metropolitan area. According to our analysis, the demand for new indicators stems from the exploration of novel PCAET governance models. This explains the search for indicators within the scope of the plan's actions, at the territorial or thematic level supported by stakeholders, and the requirement for monthly data to foster a shared vision with local stakeholders.
