France · Founded 2014Gaïago
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.
Why Gaïago leads
Direct soil carbon measurement
Field sampling per FAO 2020 protocol, verified by accredited Gold Standard third party
+3 tCO₂e/ha/yr removal
Average performance measured across 5,000 ha, top of the European range for soil carbon
A viable transition for the farmer
Carbon revenues of about €100/ha/yr measured on cohort 1, covering the bulk of transition costs. Combined with higher agricultural yields, the bottom line is a net win for the farmer.
"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
