“Data must become the new benchmark for the green transition”

Lhe COP27 confirmed what the summer of 2022 and the current energy crisis had outlined: it is no longer possible to wait to implement the transitions. Data, of all kinds, is an essential tool for managing these transitions.

Because, to act effectively and on time, it is necessary to know and understand the transformations that impact our environments more and more frequently and violently. You have to be able to “decide in real time” to respond to crises. This implies a work of observation, description, analysis and prediction in a common language which we must take stock of. It is this work that the actors of an expanding sector work on a daily basis: that of data. Often invisible, it is nevertheless one of the conditions for the enlightened deployment of public policies for the ecological and energy transition. Like geographic data, this data sector is also a key issue for French sovereignty.

The megafires have drawn attention to monitoring the state of forests. But how do you get this valuable information? It is the role of major national programs to set up benchmarks, such as theIGN forest inventory. Then, to anticipate risks, this data must be cross-checked with that of local authorities, Météo-France and INSEE. The data does not only make it possible to know the state of the territory at a given moment: the development of automatic and predictive models mobilizing artificial intelligence accelerates the processing of information. Visualizing this data then makes it possible to calibrate preventive or palliative actions: this is the challenge of digital twins, intended to model our environment in 3D to simulate its future evolution according to environmental, political and human dynamics.

Equipping democratic debate

Sobriety therefore requires a mapping of the buildings that have the greatest potential for thermal renovation: here again, databases must be created, complex calculations of energy performance, individual consumption, etc. must be made within an ethical and protective framework. private life. The same is true for the purpose of “zero net land take” (ZAN)in 2050, which requires benchmarks to know land use.

Technical at first glance, this investment in data concerns us all: it must become the equivalent of what we experienced more than two centuries ago, with the creation of the standard meter. We need these reference data to have a common language and to equip the democratic debate. Let’s take the example of soil artificialisation: if everyone refers to different data, conflicts will generate blockages in spatial planning projects and real estate projects. The land use referential is necessary for town planning documents.
