This arable farming project on 204.61 hectares in the municipality of Illiers-Combray follows the Grandes Cultures method: the farm changes its cropping practices to reduce greenhouse gas emissions and store carbon in its soils. Labelled under the Label Bas-Carbone, it targets 957 tonnes of CO₂e of expected emission reductions and soil carbon storage over its duration: they will be recognised after verification.
Practices chosen by the farmer in this project's action plan.

Les couverts végétaux sont des plantes semées entre deux cultures principales pour ne jamais laisser le sol nu. Ils capturent le CO₂ atmosphérique par photosynthèse et le stockent dans le sol sous forme de matière organique quand ils sont détruits. Ils réduisent aussi l'érosion et améliorent la structure du sol.

L'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.

L'agriculture de précision utilise la technologie (GPS, capteurs, drones, cartographie satellite) pour adapter les pratiques parcelle par parcelle, voire mètre par mètre. Elle permet de n'appliquer des intrants que là où la plante en a vraiment besoin, au bon moment.

Les légumineuses (trèfle, luzerne, féverole, pois) ont une capacité unique : elles captent l'azote de l'air grâce à des bactéries symbiotiques dans leurs racines (nodosités). Elles n'ont donc pas besoin d'engrais azotés et en laissent dans le sol pour la culture suivante.
Beyond its climate effect, each project acts on the environment and the local area. Here is the assessment of this project, dimension by dimension.
This project targets 957 tonnes of CO₂e of expected emission reductions and soil carbon storage over its duration: they will be recognised after verification. The Grandes Cultures method compares, field by field, emissions and soil carbon before and after the change in practices. Work on nitrogen (nitrogen fertilisation, variable-rate fertilisation and legumes) limits nitrous oxide (N₂O) emissions from fertilisers. The action plan also includes cover crops: the carbon they store in soils is counted by the method.
Cover crops provide shelter and food for farmland wildlife.
Cover crops capture nitrogen left in the soil between two crops and so limit nitrate leaching into water.
Soil carbon storage is part of what the method counts: the planned cover crops add organic matter to soils.
This project of 204.61 ha in Illiers-Combray supports an arable farm in changing its practices.
The 17 SDGs are a global framework defined by the United Nations to build a sustainable future by 2030. This project directly contributes to 5 of them. Here's why.
Zero Hunger
End hunger, achieve food security and improved nutrition
Why this project: This project supports an arable farm in Illiers-Combray that keeps producing: it contributes to food production with lower greenhouse gas emissions.
Clean Water and Sanitation
Ensure availability and sustainable management of water
Why this project: By capturing soil nitrogen between two crops, cover crops protect the quality of groundwater and rivers.
Responsible Consumption and Production
Ensure sustainable consumption and production patterns
Why this project: This project shifts cropping practices on 204.61 ha towards lower-emission production, with better-adjusted nitrogen fertilisation.
Climate Action
Take urgent action to combat climate change and its impacts
Why this project: This is the primary impact: this project targets 957 tonnes of CO₂e of expected emission reductions and soil carbon storage under the Label Bas-Carbone framework: they will be recognised after verification. Every ton avoided or stored in soils helps limit climate change.
Life on Land
Protect, restore and promote sustainable use of terrestrial ecosystems
Why this project: Soils covered for longer and more varied crops support soil life and farmland wildlife.

Transition to low-carbon farming practices: cover crops, reduced tillage, legumes, fine-tuned nitrogen fertilisation. The method leverages every tool available across the farm.
The Label Bas-Carbone is the official framework of the French Ministry of Ecological Transition for emission reduction projects carried out in France. A project is labelled on the basis of its application, following a method approved by the ministry. Its emission reductions are then verified by an independent auditor before being recognised by the ministry.
How it works:
1. The project owner submits a file describing the reference scenario (without project) and the project scenario.
2. The difference between the two scenarios gives the net emission reductions, expressed in tons of CO₂ equivalent.
3. An independent auditor verifies the data in the field and validates the calculations.
4. The ministry issues the Low-Carbon Label and carbon credits are issued.
5. The project is monitored for 5 years with periodic verifications.
