How this project is verified

Soil carbon is measured on site with a licensed agronometer and cross-checked by an independent laboratory. Removals are certified under ONCRA's Land Stored Carbon Protocol and registered in the public ledger, so each credit can be traced and cannot be used twice. Follow-up measurements take place every three years.

ONCRA — Open Natural Carbon Removal AccountingONCRA certified project

Nadine and Éric Sourbé were seeking a project that would allow them to cultivate their land in a manner respectful of the environment, while also providing a legacy for future generations. After thoughtful consideration, they chose to focus on bamboo due to its positive impact on French soils and the environment as a whole. They are now very eager to establish bamboo production in the Périgord–Dordogne region in order to contribute to agricultural development.

Four steps

How does it work?

From choosing a farm to a certificate in the public ledger — usually within one working day.

01

Choose your project

Every project is a named European farm with its own measurements, coordinates and ledger entry. Pick the one you want to support.

02

Request

Set how many tonnes you want to remove and send your request. We confirm availability and send you a quote.

03

Registration

Your removal is registered in the public ONCRA ledger, which is what prevents the same tonne being sold twice.

04

Certificate & impact

You receive your certificate by email, and the farmer receives the income that keeps the field growing.

Beyond carbon

Bamboo is more than just removing CO₂

What makes bamboo stand out compared to other crops?

Carbon below ground

Soil that recovers

Roots hold soil against erosion, improve water retention and rebuild depleted agricultural land, storing carbon below ground as well as above it.

Habitat, not monoculture

Biodiversity returns

A bare field becomes a year-round green forest that shelters insects, birds, mice and boars, and keeps doing so between harvests.

Raw material for industry

Feeds the green economy

Harvested culms feed the bio-based industry, replacing steel, plastic and concrete — materials with a far higher carbon footprint.

A viable business model

A second income for farmers

Carbon certificates give farmers a second income stream, which is what makes planting bamboo on marginal land viable in the first place.
