Our flagship partner
Gaiago is the pioneer of regenerative agriculture in France, with 12+ years of expertise and the world's largest Gold Standard certified soil carbon credit programme.
Pioneer of regenerative agriculture in France
Gaïago is a French company founded in 2014, specialising in soil-fertility solutions and regenerative agriculture. Its carbon programme mobilises cohorts of French farmers around a Gold Standard SOC 402.3 methodology, with satellite monitoring via Regrow. The company supports each partner farm from initial enrolment through to annual verification.
"Outstanding agronomic performance: over 3 tCO₂e captured per hectare per year, with proven environmental and social co-benefits. An industry-leading certification standard and a rigorous protocol combining on-site measurement with dMRV via Regrow."

Nature-based credit specialists
We operate at the intersection of carbon markets, certification standards, and project development. We know what separates a high-integrity credit from a liability, and we apply that lens to every project we consider.
Uncompromising project selection
We only work with projects that meet the market's recognised certification standards, Gold Standard, Verra VCS, ISO 14064-2, with a preference for methodologies aligned with the ICVCM Core Carbon Principles, and that deliver meaningful co-benefits: biodiversity, soil health, water, and farmer livelihoods. We source from France and across Europe.
A partner across your entire climate journey
Carbon contribution is not a one-off purchase, it is a multi-year strategy aligned with your climate trajectory. We help you structure, document, and evolve your contribution over time, from first credit to long-term offtake, in step with your commitments.
Fund the regeneration of European soils.
The BVCM framework and SBTi standards recognise that credible climate leadership goes beyond internal reduction: it means actively contributing to projects that sequester carbon and restore natural systems. High-integrity carbon credits from certified projects offer exactly that: a traceable, communicable, and scientifically rigorous contribution, rooted in real landscapes across France and Europe.
We help you:
- Select the right credits for your residual emissions and SBTi pathway
- Document your contribution for CSRD reporting and stakeholder communication
- Build an authentic climate narrative, grounded in verified impact, not assumptions
CSRD & BVCM ready
Documented credits with registry traceability, co-benefits data, and reporting-ready formats.
Authentic storytelling
Real French and European farms. Real farmers. Real impact you can communicate without hesitation.
100% independent
No project development, no fund management. A transparent marketplace: no hidden fees, no exclusivity.
French and European regenerative agriculture. Institutional-grade quality.
A new generation of Gold Standard certified agricultural projects is maturing across France and Europe, combining rigorous soil carbon methodology with peer-reviewed MRV and strong co-benefits. New farmer cohorts are entering certification pipelines for 2027 and beyond.
Arka structures long-term offtake agreements on behalf of its project partners, giving serious institutional buyers early access to differentiated agricultural carbon supply, before projects reach the open market.
What we offer:
- Forward purchase agreements on upcoming project cohorts
- Multi-year commitments with contractual quality assurance
- Direct access to French and European agriculture, an underrepresented origin in most carbon portfolios
Certified soil carbon
Soil carbon sequestration, Gold Standard certified, methodology under ICVCM assessment. High permanence. Peer-reviewed MRV.
Upcoming cohorts
New farmer groups entering the certification pipeline for 2027 and beyond. Early conversations welcome.
Transatlantic deal flow
Connecting leading European regenerative agriculture with US and global institutional demand.
Understand before you act
Carbon contribution is a strategic lever, not just a purchase. Here are the fundamentals.
Understanding carbon credits from regenerative agriculture
What carbon contribution is, and why companies are turning to it
Carbon contribution is the framework progressively replacing offsetting. Instead of claiming a 'carbon neutrality' increasingly contested by the SBTi, ADEME and French anti-greenwashing law, committed companies finance sequestration or reduction projects beyond their value chain, without any neutralisation claim. The SBTi's BVCM (Beyond Value Chain Mitigation) framework, published in February 2024, formalises this approach in four steps: 1.5°C trajectory, reduction plan, carbon contribution and transparent communication. To go further, see our guide on carbon contribution.
How soil carbon credits from regenerative agriculture work
French agricultural soils have a substantial carbon sequestration potential, documented by INRAE and championed by the '4 per 1000' initiative launched in 2015. When a farm adopts regenerative practices (cover crops, reduced tillage, long rotations, biostimulants), it increases its soils' organic carbon stock and generates certified carbon credits. Observed ranges are 1 to 3 tCO₂e sequestered per hectare per year. Each credit is validated by an MRV protocol combining satellite measurements, field sampling and independent auditor verification. Technical details in our soil carbon guide.
The role of an independent marketplace specializing in nature-based credits
An independent carbon marketplace like Arka brings three main functions: project selection using criteria aligned with ICVCM's Core Carbon Principles, verification of Gold Standard or ISO 14064-2 compliance, and CSRD-ready documentary packaging. Independence is essential: Arka is not a project developer and has no interest in pushing one methodology or standard over another. This neutral stance allows us to recommend the combination best suited to your context (Gold Standard for international rigour, ISO 14064-2 for projects outside the Gold Standard window, Label Bas-Carbone for France anchoring). To understand our approach, see why choose Arka.
Why traceability and CSRD documentation matter
The CSRD directive requires European companies to be fully transparent about their climate strategy, and the ESRS E1 standard specifically asks, in its E1-7 disclosure, to document GHG reduction and removal projects financed beyond the value chain. This includes certification standard, vintage, geography, volume, registry status and articulation with the reduction trajectory. Without this documentation, the auditor can issue a reservation on the climate section of the report. All credits sourced by Arka come with a complete file: registry retirement certificate, PDD, monitoring reports, attestation letter and ESRS E1 methodological memo. More details on the buyers page or in our CSRD guide.
Nicolas Bonnet, founder
I founded Arka with a conviction: voluntary carbon markets, when built on rigorous standards, are one of the most powerful tools to finance the ecological transition, and to make carbon a genuine currency of environmental value.
Our work focuses on linking high-quality carbon credit supply with corporate buyers, intermediaries, and institutional capital engaging with climate and natural capital markets. We support project developers and climate ventures in structuring demand: through corporate spot purchases, offtake agreements, strategic buyer relationships, and market access development.
With an engineering background, I spent more than 14 years in technology ventures (including 8 in the US) in data analysis or product, operations, and business development roles. For several years, I have dedicated myself to the voluntary carbon markets: mapping high-integrity projects, understanding certification standards, and establishing connections between supply and demand to build market liquidity.
