Seedlings planned in the project file
Located in the heart of Nouvelle Aquitaine, this afforestation project spans 12.45 hectares in the municipality of Maurrin ; Pujo-le-Plan. Labelled under the Label Bas-Carbone, it is expected to sequester 2,653 tons of CO₂ over its lifetime (expected emission reductions, recognised after verification). The project file plans 15,562 seedlings of a single species (pin maritime): this project creates a new forest cover and its carbon sink.
1.1FTE-years of forestry work mobilised over 30 years
This project mobilises about 1.1 years of full-time forestry work (between 0.8 and 1.8), spread over the project’s 30 years.
Method: planted area × working hours per hectare published by the ONF (technical itineraries 2011-2015), over the project’s 30 years; audit: 5 to 10 days depending on area (Stock CO₂ data); harvesting: harvested volumes (ONF, Fournier et al. 2022) × harvester and forwarder productivity (FCBA 2005); ÷ 1,607 h, the French statutory annual working time; nurseries not quantified; Stock CO2 estimate.
Species diversity strengthens forest resilience against diseases and climate change.

Pinus pinaster · Pinaceae
Espèce emblématique du massif landais, il peut atteindre 30 m. Son bois est utilisé en papeterie et construction. Il a été massivement planté au XIXe siècle pour fixer les dunes.
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 is expected to sequester 213.1 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.
With 1 different species (low diversity), this project creates a rich habitat for wildlife. The ecological corridors formed allow species to circulate, promoting pollination and natural biological pest control.
Over 12.45 ha, the forest cover acts as a natural filter. Roots promote water infiltration into soils, reduce runoff and erosion, and enable groundwater recharge.
With 1250 seedlings planned per hectare, the root system structures the soil in depth. Litter (dead leaves, twigs) enriches organic matter, feeds soil microorganisms and increases water retention capacity.
This project of 12.45 ha in Maurrin ; Pujo-le-Plan relies on field work for its implementation, maintenance and monitoring, and helps enhance the territory and its natural heritage.
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.
Clean Water and Sanitation
Ensure availability and sustainable management of water
Why this project: The forest cover on 12.45 ha naturally filters runoff water and promotes groundwater recharge. By reducing erosion and nutrient leaching, this project improves water quality available for local uses.
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.
Responsible Consumption and Production
Ensure sustainable consumption and production patterns
Why this project: The 15,562 trees planned on 12.45 ha will in the long term form a renewable wood resource, from a forest monitored for the whole project duration.
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 2,653 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.
Life on Land
Protect, restore and promote sustainable use of terrestrial ecosystems
Why this project: This project of 12.45 ha in Maurrin ; Pujo-le-Plan recreates a forest ecosystem: wildlife habitat, ecological corridors and richer soil biodiversity.

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.
