Socio-economic benefits
1.2FTE-years of forestry work mobilised
This project mobilises about 1.2 years of full-time forestry work (between 0.9 and 1.7), spread over the planting and maintenance years.
Method: planted area × working time per hectare published by the ONF (technical itineraries 2011-2015), ÷ 1,607 h, the French statutory annual working time; direct forestry work only, excluding nurseries and transport; Stock CO2 estimate.

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
98%
This project is expected to sequester 215.0 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
Very high impact92%
With 11 different species (strong diversity), this project creates a rich habitat for wildlife. The ecological corridors formed allow species to circulate, promoting pollination and natural biological pest control.
Water
Very high impact98%
Over 22.11 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
Very high impact98%
With 1517 trees/ha, 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 impact90%
This project of 22.11 ha in Bretignolles-sur-Mer 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 6 of them. Here's why.
3
Good Health and Well-being
Ensure healthy lives and promote well-being for all
Why this project: This project contributes to this goal through its carbon sequestration actions and strengthening of local ecosystems.
6
Clean Water and Sanitation
Ensure availability and sustainable management of water
Why this project: The vegetation cover on 22.11 ha naturally filters runoff water and promotes groundwater recharge. By reducing erosion and nutrient leaching, this project improves water quality available for local uses.
8
Decent Work and Economic Growth
Promote sustained, inclusive and sustainable economic growth
Why this project: This project contributes to this goal through its carbon sequestration actions and strengthening of local ecosystems.
12
Responsible Consumption and Production
Ensure sustainable consumption and production patterns
Why this project: The sustainable forest management of this project of 22.11 ha ensures responsible wood production: planted trees will eventually provide timber or energy wood, replacing high carbon footprint materials.
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 4,754 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: This project of 22.11 ha in Bretignolles-sur-Mer plants 11 different species, recreating a complete forest ecosystem: wildlife habitat, ecological corridors, and soil biodiversity enrichment through mycorrhizal fungi.

Label Bas-Carbone method · Afforestation
Planting a forest on land that has not been wooded for at least 10 years. The project stores carbon in biomass (trunks, branches, roots), soils and durable wood products.
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 30 years with periodic verifications.
