Meet the carbon removers
What does Oncra stand for?

Open. No up-front costs, radical transparency, understandable and accessible data means everyone can join the cleanup.
Natural. All projects Oncra supports are nature-based and have positive impacts on ecosystem integrity.
Carbon. Carbon is the building block of the New Nature Economy, which is circular and biobased. Oncra projects accelerate this transition.
Removal. To remove excess CO2 from the atmosphere, Oncra only quantifies and certifies real, measurable carbon dioxide removal.
Accounting. Oncra provides tools, protocols and services that make carbon accounting and monetisation accessible to all.
The framework
Oncra certifies projects that store carbon in rocks, oceans, constructions and land.

Rock stored carbon
Rock Stored Carbon measures the sequestration of atmospheric CO2 through enhanced weathering of rocks and minerals, such as olivine. In effect, this technique replicates the process of soil formation, the basis of all terrestrial life.

Construction stored carbon
Construction Stored Carbon measures the long-term storage of biogenic carbon in biobased materials, buildings and infrastructure.

Land stored carbon
Land Stored Carbon measures the enhanced sequestration of atmospheric CO2 by terrestrial (agricultural) ecosystems. It measures increases in above-ground biomass, below-ground biomass and stable biomass (e.g., biochar).

Ocean stored carbon
Ocean Stored Carbon measures the enhanced sequestration of atmospheric CO2 by marine (agricultural) ecosystems. Solutions include mangroves, seaweed, seagrass, oysters, biomass sinking, and much more. The potential is limitless!
