Project presentation
In Paris, a bâtiment project spans 1.71 hectares. Certified under France's Label Bas-Carbone, it contributes to the sequestration of 550 tonnes of CO₂ while enhancing local biodiversity, soil health, and ecosystem resilience. A concrete investment for climate and communities.
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
82%
This project sequesters 321.5 tCO₂/ha over its lifetime. 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
Low impact35%
This project creates a rich habitat for wildlife. The ecological corridors formed allow species to circulate, promoting pollination and natural biological pest control.
Water
Low impact30%
Over 1.71 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
Low impact25%
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 impact85%
This project of 1.71 ha in Paris supports the local economy: direct jobs (planting, maintenance, monitoring), enhancement of the territory and 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 4 of them. Here's why.
7
Affordable and Clean Energy
Ensure access to affordable, reliable and sustainable energy
Why this project: This project contributes to this goal through its carbon sequestration actions and strengthening of local ecosystems.
11
Sustainable Cities and Communities
Make cities and settlements inclusive, safe and sustainable
Why this project: By integrating bio-based materials into construction, this project reduces the carbon footprint of urban buildings and contributes to making cities more sustainable.
12
Responsible Consumption and Production
Ensure sustainable consumption and production patterns
Why this project: This project contributes to responsible consumption and production by substituting low-carbon solutions for conventional practices.
13
Climate Action
Take urgent action to combat climate change and its impacts
Why this project: This is the primary impact: this project sequesters 550 tons of CO2 over its lifetime, certified by the Low-Carbon Label. Every ton removed from the atmosphere directly contributes to fighting climate change.

Label Bas-Carbone method · Bio-based buildings
Construction using bio-sourced materials (wood, straw, hemp) that store carbon durably in the building structure.
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 (they would not have occurred without the project). Each project is audited by an independent body before labelling, then monitored throughout its duration.
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 50 years with periodic verifications.
