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.
Photo 1 of 4Soil 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 certified projectWim Straathof has planted 3 hectares of bamboo in Creil, in the Dutch Noordoostpolder, where his young bamboo field grows between the wind turbines of the polder. Wim holds the legal ownership of the carbon his bamboo removes and has committed to caring for the land for at least 20 years. As the bamboo grows into a closed forest, it stores carbon in its roots and in the soil, year after year.
Four steps
From choosing a farm to a certificate in the public ledger — usually within one working day.
Every project is a named European farm with its own measurements, coordinates and ledger entry. Pick the one you want to support.
Set how many tonnes you want to remove and send your request. We confirm availability and send you a quote.
Your removal is registered in the public ONCRA ledger, which is what prevents the same tonne being sold twice.
You receive your certificate by email, and the farmer receives the income that keeps the field growing.
Beyond carbon
What makes bamboo stand out compared to other crops?

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

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

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

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