The new Label Bas Carbone, a deep dive into France's 2025 carbon credit reforms

Like a forest shedding its bark to grow stronger, France's national carbon standard is undergoing a profound transformation. The French Ministry for Ecological Transition has officially declared that its flagship certification, the Label Bas Carbone (LBC), is getting a "new skin"—fait peau neuve.

This is not a minor facelift; it's a fundamental restructuring of the rules governing nature-based carbon projects in one of Europe's key climate markets. 

Since its inception, the LBC has been a critical tool for channeling private capital into domestic projects that reduce greenhouse gas emissions and sequester carbon, from reforesting fire-ravaged landscapes to pioneering low-carbon farming techniques. It stands as a cornerstone of France's National Low-Carbon Strategy (Stratégie Nationale Bas Carbone or SNBC), the country's roadmap to achieving carbon neutrality by 2050. 

But now, with the publication of a new decree and arrêté (ministerial order) on September 5, 2025, the game has changed. The reforms promise greater transparency, simplified financing, and increased project flexibility. More importantly, they unlock a true market for French carbon credits, making them fully tradable for the first time. For investors, project developers, and corporate leaders focused on credible climate action, understanding this evolution is no longer optional—it's essential for navigating the future of European nature-based investments. 

This deep dive will dissect the LBC's transformation, exploring its foundational principles, the sweeping changes of the 2025 reform, its real-world impact, the persistent controversies, and what this all means for the future of high-integrity carbon markets. 

I. The foundation: the Label Bas Carbone before 2025

To grasp the magnitude of the 2025 reforms, we must first understand the framework they replace. Established by a decree on November 28, 2018, the Label Bas Carbone was France's answer to a growing demand for domestic, high-quality carbon offsetting projects. Its primary goal was to create a state-guaranteed standard that could assure investors of the environmental integrity of projects, reducing emissions on French soil. 

The initial framework was ambitious but, in hindsight, restrictive. Its defining characteristic was how it treated the carbon units generated.

They were termed "réductions d’émissions" (emission reductions) and were, crucially, neither transferable nor exchangeable on any market. Once a company financed a project and the reductions were verified, those units were effectively retired and could only be used for that company's voluntary offsetting claims. 

This initial design, while ensuring a direct link between a funder and a project, created significant friction. It limited market liquidity, making it harder for project developers to secure upfront financing and for investors to manage their portfolios. A first revision in 2021-2022 began to address these issues by decentralizing project approvals, but the core limitation remained. 

This initial framework laid the groundwork and proved the concept, but as the voluntary carbon market matured and the scale of the climate challenge demanded faster, more flexible financial mechanisms, a more robust system became imperative. That imperative drove the major overhaul of 2025. 

II. The 2025 reform: a new framework for carbon action

 

The new decree and arrêté of September 5, 2025, are the result of extensive consultation with over 50 key stakeholders—from project managers to financiers—and represent a deliberate shift from a static certification to a dynamic market mechanism. The changes are sweeping, targeting everything from terminology to market mechanics. 

1. Official renaming & unlimited credit transferability

The most significant change is a fundamental shift in the nature of the asset itself. 

• From "Reductions" to "Carbon Credits": The old "réductions d’émissions" are now officially designated as "crédits carbone" (carbon credits), as outlined in Articles 1 and 2 of the new arrêté. This aligns the LBC with global market terminology. 

• Unlimited and Retroactive Cessibilité: The reform introduces unlimited and retroactive transferability (cessibilité) for all verified carbon credits (Article 26). This is a game-changer. Credits can now be bought and sold multiple times, creating the market liquidity that was previously absent. This boosts the financial viability of long-term projects and provides investors with greater flexibility. 

• New "Withdrawal" Procedure: The old "recognition" step is replaced by a "withdrawal" procedure (Article 27). A credit owner initiates this to officially use the credit for their climate claim, at which point it becomes the property of the "final beneficiary" and its transferability ends. This clear endpoint prevents double-counting and enhances accountability. 

  
  

Crucially, these changes make the LBC fully compatible with the European Union's Corporate Sustainability Reporting Directive (CSRD), ensuring that investments in LBC projects can be seamlessly integrated into mandatory corporate ESG reporting. 

What is the CSRD? 

The Corporate Sustainability Reporting Directive (CSRD) is a European Union regulation requiring large companies to disclose information on their environmental and social impacts. By aligning with CSRD, the Label Bas Carbone ensures that the carbon credits generated are recognized within this stringent reporting framework, increasing their value and relevance for European corporations. 

 

2. Enhanced flexibility for collective projects 

Many nature-based projects, especially in agriculture, aggregate numerous small landowners into a single collective. The new rules make managing these complex arrangements far easier. 

• Changing Representatives: Groups of project participants (at least 20%) can now choose to split from a collective project and appoint a new representative (mandataire), whereas previously the entire project had to be transferred as a single block (Article 24). 

• Modification Tolerance: The rules now define an acceptable margin for modifying a collective project during its formation, providing clarity for developers and streamlining the review process for officials (Article 23). 

3. Radically strengthened transparency 

To build investor confidence and combat greenwashing, the reforms mandate a new level of transparency. 

• Mandatory Funding Declaration: Project developers must now declare all financing received in the public LBC registry within three months of signing a contract, even before credits are verified (Article 28). For existing projects, this must be done by September 5, 2026. 

• Price Transparency: When a verified credit is sold, the seller and buyer must report the unit sale price to the authorities within three months (Article 29). This data, anonymized and aggregated, will allow the government to publish regular market analyses. 

• Open-Source Calculators: The official LBC website will now display the carbon calculators and co-benefit spreadsheets for methodologies where this is feasible, allowing for public scrutiny and academic review of project claims (Article 5). 

  
  

4. Refined governance and method approval 

The quality of a carbon credit is only as good as the methodology behind it. The new framework tightens the criteria for approving new project types. 

• Stricter Eligibility: New methods must now be evaluated on their impact on biodiversity, their potential scale (number of projects and carbon volume), and their foundation in existing scientific literature (Article 15). 

• Systematic Scientific Review: The Scientific and Technical Group (GST), an independent advisory body, must now be convened for every new or revised methodology, and its expert report must be published (Article 18). 

5. Formalizing pilot projects 

To foster innovation while ensuring rigor, the arrêté formally introduces the ability to launch pilot projects (Article 14). This allows new, promising methodologies to be tested in the real world, generating crucial data to refine their parameters before a full-scale rollout. 

These 5 sweeping changes are designed to supercharge the LBC's effectiveness. But what has been the label's impact on the ground thus far? 

III. The Label Bas Carbone in action: growth and real-world impact 

Despite its initial limitations, the LBC has successfully catalyzed significant climate action across France. The data reveals a story of exponential growth. 

• As of March 31, 2025, 1,685 projects had been validated, representing a potential climate impact of 6.41 million tonnes of CO2 equivalent (MtCO2eq). 

• This growth is accelerating: the ~2.8 MtCO2eq in potential credits validated in 2024 alone was double the volume from 2023. 

• By September 18, 2025, the number of labeled projects had climbed to 1,935, with a potential of over 7.2 million tonnes. 

This activity is concentrated in France's two largest carbon sinks: forests and agricultural lands. 

Forestry projects, numbering over 1,200 and covering 12,000 hectares, account for a potential 3.3 MtCO2eq. These aren't monolithic monocultures but diverse, targeted interventions. For instance: 

• Restoration After Fire: Following the devastating 2022 wildfires, 93% of LBC fire-restoration projects (1.02 MtCO2eq potential) are concentrated in the Nouvelle-Aquitaine region, helping rebuild critical ecosystems. 

• Afforestation: Projects are creating new forests on 3,800 hectares of land, 83% of which was former agricultural land, sequestering a potential 1.26 MtCO2eq. 

• Combating Disease: In response to the bark beetle epidemic, projects are restoring 3,300 hectares of damaged forests in northeastern France (0.71 MtCO2eq potential). 

In agriculture, approximately 3,500 farms are engaged in LBC projects, implementing low-carbon practices under methodologies like "CarbonAgri" (livestock) and "Grandes Cultures" (arable crops). These projects generate an average impact of 1 tCO2eq per hectare per year. 

Financially, the LBC has commanded a premium, with an average sales price of €33 per tonne of CO2eq, significantly higher than prices on the international voluntary market. This reflects investor confidence in the quality and locality of the projects. 

While these figures highlight undeniable progress, the LBC has not been without its critics. Several challenges and intense debates persist regarding its design and true impact. 

IV. Controversies and Challenges: a delicate balance 

For any carbon standard, the difference between catalyzing genuine climate action and enabling greenwashing should be clear. The LBC is no exception.

Key areas of controversy include: 

• Greenwashing and Offsetting vs. Reduction: The core ethical debate is whether the LBC encourages companies to offset emissions rather than prioritize their absolute reduction. Critics argue that by allowing companies to buy credits, the label may inadvertently provide a license to continue polluting, particularly for sectors like industrial agriculture. 

• Methodological Integrity: 

• Additionality: The perennial question for all carbon credits: would this project have happened anyway? Proving that a project is truly "additional" remains a complex challenge. 

• Permanence: This is a major concern for agricultural projects. Carbon sequestered in soil is not guaranteed to stay there forever; a change in farming practices could release it back into the atmosphere. This makes equating soil sequestration with permanent emission reductions problematic. 

• Baseline Scenarios: The number of credits a project generates is calculated against a hypothetical "business-as-usual" baseline. Critics argue these baselines can be manipulated to inflate credit issuance. 

• Biodiversity Co-Benefits: While the 2025 reforms place greater emphasis on biodiversity, there are fears that a primary focus on maximizing carbon sequestration could lead to projects that are suboptimal or even detrimental to local ecosystems. For example, planting a fast-growing monoculture might sequester more carbon in the short term but would be an ecological disaster compared to a mixed, native forest. 

• Financial Viability for Farmers: Many agricultural projects, particularly those focused on soil carbon, have struggled to attract buyers at a price that makes the transition economically viable. The high costs of measurement, reporting, and verification (MRV) can eat into the thin margins of farmers. 

  
  

The 2025 reforms aim to provide concrete responses to many of these concerns by strengthening transparency and tightening governance requirements. Recognizing these challenges as part of the continuous evolution of the LBC is essential to consolidating its role as a credible and effective instrument in support of France’s climate ambitions. 

V. Future outlook: the growing influence of the Label Bas Carbone 

The Label Bas Carbone stands at a pivotal moment. The 2025 reforms have positioned it not just to scale up domestic climate action but also to influence the conversation across Europe. 

Several key trends will shape its future: 

• Integration with European Frameworks: The LBC's alignment with the CSRD is a strategic move. Its future relationship with the upcoming EU Carbon Removal Certification Framework (CRCF) will be critical. The LBC could serve as a successful national model for the CRCF, but it may also need to adapt further—for instance, by phasing out ex-ante crediting—to remain attractive to international investors operating under a unified European standard. 

• Continuous Methodological Improvement: The LBC system is a learning-by-doing process. Ongoing refinements to carbon quantification, realistic accounting for substitution effects (e.g., using timber instead of concrete), and applying conservative discounts (currently averaging 22%) to account for risks like wildfires or project failure will be essential for maintaining credibility. 

• Expansion into New Sectors: With successful methodologies in forestry and agriculture, the LBC is expanding. New methods for building renovation, bio-sourced construction, urban greening ("Tree City"), and even seagrass meadow restoration ("Herbiers de Posidonie") demonstrate the label's potential to drive innovation across the entire economy. 

The Label Bas Carbone is more than a certification; it's a national experiment in pricing and financing nature-based climate solutions. Its success will depend on its ability to navigate the complex trade-offs between market efficiency and environmental integrity. 

VI. A new chapter for French carbon finance 

The 2025 overhaul of the Label Bas Carbone marks a definitive shift from a promising but constrained pilot phase to a mature, market-ready framework. By embracing tradable credits, radical transparency, and stricter governance, France is betting that it can accelerate private investment into nature-based solutions while safeguarding the integrity of its climate claims. 

For investors, this evolution presents a compelling, albeit complex, opportunity. The increased liquidity and alignment with European reporting standards reduce key market risks. However, the persistent controversies around additionality, permanence, and greenwashing demand more rigorous due diligence than ever. 

The ultimate question is not whether investments in nature-based solutions matter—it is whether those investments are robust, credible, and truly delivering for the climate. The new Label Bas Carbone provides a powerful framework, but the responsibility remains with project developers and their financial partners to ensure every credit is backed by unquestionable environmental integrity. The next chapter of France's climate story is now being written in its forests, fields, and cities, financed by a carbon market that has finally come of age.
