Project presentation
This agricultural project on 108 hectares in the municipality of BILLÉ implements responsible practices designed to reduce greenhouse gas emissions and increase carbon storage in soils, with 534 tons of CO₂ of expected emission reductions over its lifetime. Labelled under the CARBON AGRI method of the Label Bas-Carbone, it promotes more resilient and sustainable agricultural ecosystems.

Valorisation du pâturage
Moyen — réduction des consommations d'énergie + stockage carbone dans les prairiesAugmenter la durée et la qualité du pâturage permet aux vaches de se nourrir directement de l'herbe plutôt que de fourrages récoltés et de concentrés. Le pâturage bien conduit maintient les prairies en bon état et réduit les coûts d'alimentation.
Did you know?
Le saviez-vous ? Une vache au pâturage consomme zéro litre de carburant pour son alimentation — pas de récolte, pas de transport, pas de distribution. Le pâturage est le mode d'alimentation le plus sobre en énergie.

Autonomie protéique
Fort — la substitution du soja importé est l'un des leviers les plus puissants en élevageL'autonomie protéique consiste à produire sur la ferme les protéines nécessaires à l'alimentation du troupeau, plutôt que d'acheter du tourteau de soja importé. Cela passe par la culture de colza, féverole, luzerne ou pois, et par l'optimisation des fourrages.
Did you know?
Le saviez-vous ? Pour produire 1 kg de tourteau de soja importé du Brésil, il faut déforester 3 m² de savane du Cerrado. Remplacer ce soja par de la féverole locale supprime cette empreinte.

Qualité des fourrages
Moyen — amélioration de la digestibilité réduisant le méthane entérique de 5 à 15 %Améliorer la qualité des fourrages (meilleure valeur énergétique UFL, plus de protéines MAT) permet de réduire la quantité de concentrés achetés et de mieux valoriser les ressources de la ferme. Un fourrage récolté au bon stade nourrit mieux et réduit le gaspillage.
Did you know?
Le saviez-vous ? Un foin récolté au bon stade (début épiaison) contient 30 % d'énergie en plus qu'un foin récolté trop tard. Cette différence se traduit directement en moins de méthane émis par la vache.
Environmental & social impacts
Beyond carbon sequestration, each project generates measurable positive impacts on the environment and local communities. Here is the detailed assessment of this project.
🌍Climate
76%
This project is expected to sequester 4.9 tCO₂/ha over its lifetime (expected reductions, recognised after verification). Carbon is captured in biomass (trunks, branches, roots) and soils. This is the project's primary impact: contributing to climate change mitigation by removing CO₂ from the atmosphere.
Biodiversity
Significant impact72%
This project creates a rich habitat for wildlife. The ecological corridors formed allow species to circulate, promoting pollination and natural biological pest control.
Water
Significant impact78%
Over 108 ha, the vegetation cover acts as a natural filter. Roots promote water infiltration into soils, reduce runoff and erosion, and enable groundwater recharge. Downstream water quality is directly improved.
Soils
High impact89%
The root system structures the soil in depth. Litter (dead leaves, twigs) enriches organic matter, feeds soil microorganisms and increases water retention capacity. A living, fertile soil is the foundation of a resilient ecosystem.
Socio-economic
High impact82%
This project of 108 ha in BILLÉ relies on field work for its implementation, maintenance and monitoring, and helps enhance the territory and its natural heritage. It strengthens the link between rural communities and their environment, contributing to the ecological transition.
Sustainable Development Goals
The 17 SDGs are a global framework defined by the United Nations to build a sustainable future by 2030. This project directly contributes to 4 of them. Here's why.

Zero Hunger
End hunger, achieve food security and improved nutrition
Why this project: With 108 ha of sustainable farming practices in BILLÉ, this project improves long-term soil productivity, secures food yields and strengthens farm resilience against climate risks — directly contributing to local food security.
12
Responsible Consumption and Production
Ensure sustainable consumption and production patterns
Why this project: This project transforms farming practices on 108 ha towards more responsible production: reduced chemical inputs, soil cover, crop diversification.
13
Climate Action
Take urgent action to combat climate change and its impacts
Why this project: This is the primary impact: this project aims to sequester 534 tons of CO₂ over its lifetime under the Label Bas-Carbone framework (expected reductions, recognised after verification). Every ton removed from the atmosphere contributes to fighting climate change.
15
Life on Land
Protect, restore and promote sustainable use of terrestrial ecosystems
Why this project: By reintroducing soil-friendly practices (cover crops, hedges, reduced tillage), this project restores terrestrial life on 108 ha.
