Project presentation
This livestock project on 157.2 hectares in the municipality of Chambellay follows the Carbon Agri method: starting from a carbon assessment of the whole farm, the farmer implements an action plan to reduce greenhouse gas emissions from the herd and crops. Labelled under the Label Bas-Carbone, it targets 488 tonnes of CO₂e of expected emission reductions over its duration: they will be recognised after verification.
Agricultural levers for this project (4)
Practices chosen by the farmer in this project's action plan.
Optimisation de la fertilisation
Climate impact : FortL'optimisation de la fertilisation consiste à ajuster précisément les apports d'engrais (azote, phosphore, potassium) aux besoins réels des cultures. L'objectif est de réduire les excédents qui se transforment en protoxyde d'azote (N₂O), un gaz à effet de serre 265 fois plus puissant que le CO₂.
Âge au vêlage et longévité
Climate impact : MoyenRéduire l'âge au premier vêlage (de 36 à 24-30 mois) et augmenter la longévité des vaches permet de réduire le nombre d'animaux improductifs dans le troupeau. Moins de génisses d'élevage signifie moins de méthane entérique et plus d'efficacité par litre de lait ou kg de viande produit.
Autonomie protéique
Climate impact : FortL'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.
Réduction de la consommation énergétique
Climate impact : MoyenRéduire la consommation de carburant et d'électricité de l'exploitation passe par l'optimisation des passages d'engins, le choix de tracteurs efficients, l'isolation des bâtiments et le recours aux énergies renouvelables.
Environmental & social impacts
Beyond its climate effect, each project acts on the environment and the local area. Here is the assessment of this project, dimension by dimension.
Climate
73%
This project targets 488 tonnes of CO₂e of expected emission reductions over its duration: they will be recognised after verification. The Carbon Agri method calculates them for the whole farm, comparing its emissions before and after the action plan. Herd levers (age at first calving and cow longevity) reduce the share of unproductive animals and enteric methane emissions per unit produced. Changes in feeding (protein self-sufficiency) limit purchased feed and the emissions from producing it. Work on nitrogen (nitrogen fertilisation) limits nitrous oxide (N₂O) emissions from fertilisers. Lower energy use cut CO₂ emissions from the farm's machinery and buildings.
Biodiversity
Significant impact65%
This project acts first on livestock emissions; its effects on biodiversity depend on farm practices, such as keeping grasslands and hedges.
Water
Significant impact79%
Better management of nitrogen inputs also limits the risk of nitrate leaching into water.
Soils
Significant impact91%
This project's levers do not directly target soil carbon storage.
Socio-economic
Moderate impact84%
This project of 157.2 ha in Chambellay supports a livestock farm in changing its practices, based on an assessment of the whole farm.
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.
2
Zero Hunger
End hunger, achieve food security and improved nutrition
Why this project: This project supports a livestock farm in Chambellay that keeps producing: it contributes to food production with lower greenhouse gas emissions.
12
Responsible Consumption and Production
Ensure sustainable consumption and production patterns
Why this project: This project shifts a livestock farm's practices towards production with lower greenhouse gas emissions.
13
Climate Action
Take urgent action to combat climate change and its impacts
Why this project: This is the primary impact: this project targets 488 tonnes of CO₂e of expected emission reductions under the Label Bas-Carbone framework: they will be recognised after verification. Every ton avoided helps limit climate change.
15
Life on Land
Protect, restore and promote sustainable use of terrestrial ecosystems
Why this project: This project acts on livestock emissions; grasslands and hedges, where the farm has them, remain habitats that support life on land.
