In June 2019,INRAE delivered a study, carried out at the request of Ademe and the Ministry of Food and Agriculture, on the potential for carbon storage in soils in France. Using an original methodology, the study was able to assess this potential and estimate the cost of implementing it region by region, with a view to achieving the 4 per 1000 target. The "4 per 1000 on soils for food security and climate" initiative was launched at the 2015 Paris Climate Change Conference.
This study was conducted by INRAE's Delegation for Collective Scientific Expertise, Forecasting and Studies (DEPE). The BANCO model, combining agronomic simulations and cost calculations, was used to optimise the storage effort to be implemented.
