The NatAdGES project aims to reduce greenhouse gas (GHG) emissions from agriculture by addressing nitrous oxide (N2O) emissions. This gas has a very strong radiative power and agriculture is currently its main anthropogenic source. The proposed levers (whitewashing for climatic reasons, inoculating leguminous plants, etc.) are aimed at different types of agriculture (conventional, organic, etc.). The project also develops tools for tracking and communicating to different targets (society, the agricultural world, public policies, etc.) of achieved and achievable emission avoidance.
