Your new builds generate unavoidable residual emissions. Fund French certified Label Bas-Carbone projects and strengthen your RE2020 compliance — with impact measured across 5 ecosystem dimensions.
Obligations are multiplying. Understanding the regulatory framework turns constraints into competitive advantage and commercial differentiation.
RE2020 sets progressively stricter Carbon Impact (IC) thresholds for new construction. From 2025, requirements tighten, compelling developers to reduce each programme's carbon footprint and address residual emissions.
Thresholds tightened 2025-2028-2031The Climate Act imposes increasing energy renovation obligations for existing buildings and progressively bans renting of energy-inefficient properties (EPC F and G). Property companies must integrate carbon into their asset strategy.
EPC G rental ban from 2025The ZAN objective requires halving the rate of land artificialization by 2031. Developers must rethink their projects: densification, re-naturing, ecological compensation. Funding reforestation projects fits within this logic.
Climate and Resilience Act, art. 191Environmental certifications are becoming a prerequisite for institutional investors and local authorities in development zones. Documenting a certified Label Bas-Carbone carbon contribution strengthens certification applications.
Growing investor demandBetween RE2020 regulatory pressure, investor demands and buyer expectations, developers face growing environmental challenges.
Construction accounts for 60 to 80% of a building's carbon footprint over its lifecycle. Concrete, steel, material transport: even with bio-sourced materials, residual emissions remain.
IC construction thresholds are progressively tightened. Developers must document their low-carbon strategy and demonstrate that residual emissions are addressed in every project.
Buyers are increasingly sensitive to the environmental impact of their homes. A programme linked to local carbon contribution projects provides a concrete, verifiable selling point.
Property companies and REITs must green their real estate portfolio to meet EU taxonomy requirements and SRI investor demands. Carbon contribution complements energy renovation actions.
End-to-end support, from estimating your programme emissions to impact tracking. Everything is certified, traced and measurable.
After optimisation (bio-sourced materials, RE2020), address residual emissions from each project with certified Label Bas-Carbone projects. Registered certificates per programme.
Link your programmes to local reforestation or agroforestry projects. A concrete differentiator for your buyers and investors.

Why should a French property developer choose Label Bas-Carbone?
| Criterion | Label Bas-Carbone | VCS / Verra | Gold Standard |
|---|---|---|---|
| French government recognition | Yes — Ministry of Ecological Transition | No | No |
| Project location | France only | International (mostly emerging countries) | International |
| Territorial anchoring | Projects near your sites | No territorial link | No territorial link |
| Independent audit | Yes — accredited auditors | Yes | Yes |
| CSRD / ESRS E1 alignment | Strong — traceable projects | Medium | Medium |
| Multidimensional impact | 5 dimensions (carbon, biodiversity, water, soil, social) | Carbon mainly | Carbon + co-benefits |
| Price per tonne | 30 to 80 EUR / tCO2 | 5 to 30 EUR / tCO2 | 15 to 50 EUR / tCO2 |
| Greenwashing risk | Very low | Documented controversies (2023) | Low |

“We needed a credible solution to address residual emissions from our RE2020 new-build programmes. Stock CO2 offered us reforestation projects near our operations in Île-de-France. The Label Bas-Carbone certificates are a real asset for our HQE applications and buyer communications.

Answers to the most common questions about certified carbon contribution for property development.
RE2020 sets progressively stricter IC construction (Carbon Impact) thresholds through 2031. Developers must reduce the carbon footprint of new builds from the design stage. Carbon contribution through Label Bas-Carbone projects offsets residual emissions once all reduction levers have been exhausted, strengthening the credibility of your low-carbon approach.
Zéro Artificialisation Nette (ZAN), enshrined in the Climate and Resilience Act, aims to halve the rate of land artificialization by 2031 and reach net zero by 2050. For developers, this means densification and re-naturing. Funding certified reforestation or agroforestry projects through Label Bas-Carbone fits within this logic of territorial ecological compensation.
Yes. Label Bas-Carbone certified carbon contribution can be integrated from the project planning phase. It complements reduction actions (bio-sourced materials, RE2020) by addressing residual emissions from construction sites and materials. Registered certificates can be used in planning applications, marketing materials and CSR reports.
The HQE and BREEAM frameworks award points for documented and certified carbon contribution initiatives. Label Bas-Carbone projects, with their complete traceability and multidimensional impact (carbon, biodiversity, water, soil, social), meet the requirements of these certifications. Stock CO2 reports can be used directly in certification applications.
A low-carbon eco-district aims for environmental excellence at the neighbourhood scale. Carbon contribution addresses residual emissions from construction and development by funding local projects (forests, hedgerows, regenerative agriculture) that strengthen the territorial anchoring of the project. It is a strong commercial differentiator for buyers.
Label Bas-Carbone projects range from 30 to 80 euros per tonne of CO2. For a 50-unit residential programme, the carbon contribution budget is typically between 15,000 and 50,000 euros — a marginal cost relative to the programme's revenue. The minimum commitment at Stock CO2 is 10 tonnes of CO2.
Absolutely. The BiodiverCity label assesses how biodiversity is factored into property projects. Label Bas-Carbone projects funded through Stock CO2 are evaluated across 5 dimensions including biodiversity. Funding reforestation or hedgerow projects near your developments directly strengthens your BiodiverCity application.
