Project presentation
Le bois de la Persais is a afforestation project located in Pays de la Loire, municipality of Vallons-de-l'Erdre (Loire Atlantique). Certified Label Bas-Carbone by the Ministry of Ecological Transition using the "BOISEMENT" method, this project covers 3.82 hectares.
The carbon sequestration potential is estimated at 981 tonnes of CO₂ over the project's lifetime, an intensity of 256.8 tCO₂ per hectare.
5,385 trees were planted, comprising 4 different species at a density of 1,410 trees per hectare. This species diversity strengthens the ecosystem's resilience to climate risks and promotes local biodiversity.

Environmental & social impacts
Beyond carbon sequestration, each project generates measurable positive impacts on the environment and local communities.
🌍Climate
89%
This project sequesters 256.8 tCO₂/ha over its lifetime. Carbon is captured in biomass and soils. This is the primary impact: contributing to climate change mitigation.
Biodiversity
High impact87%
With 4 different species (moderate diversity), this project creates a rich habitat for wildlife. Ecological corridors promote pollination and biological control.
Water
Very high impact93%
Over 3.82 ha, vegetation filters water, reduces runoff and erosion, and promotes groundwater recharge.
Soils
Very high impact94%
With 1410 trees/ha, the root system structures the soil. Litter enriches organic matter and increases water retention.
Socio-economic
Significant impact73%
This 3.82 ha project in Vallons-de-l'Erdre supports the local economy: direct jobs, territory enhancement and ecological transition.

🏛️
Method · BOISEMENT
The Low-Carbon Label is an official certification framework from the French Ministry of Ecological Transition. It guarantees that emission reductions are real, measurable, verifiable and additional.
How it works:
1. The project owner submits a file describing the reference and project scenarios.
2. The difference gives net emission reductions in CO₂ equivalent.
3. An independent auditor verifies the data in the field.
4. The ministry issues the Label and carbon credits are issued.
5. The project is monitored with periodic verifications.
