Enabling millions of carbon removing entrepreneurs to sell their carbon – the right way.
Oncra is a framework that facilitates carbon removers while combining the most bespoke and accurate carbon accounting practices for nature-based solutions. Oncra was born out of necessity and the realization that all the elements for holistic accounting for nature-based solutions seemed to be in place, so given the climate and biodiversity crises it is time to connect the dots in an open, transparent, and innovation driving way.

Oncra is based on established accounting methods for carbon removal, as developed by the Intergovernmental Panel on Climate Change (IPCC), European Commission (EC), Gold Standard, Verra and initiatives like Greenhouse Gas Protocol and Platform Carbon Accounting Financials (PCAF). Methods are considered as the broad set of standards that determine how emission reductions and removals should be accounted for. As the field of carbon removal is relatively new, Oncra supports the development of sector-specific removal accounting protocols that build on the logic and accuracy of existing methods.
All Protocols contain specific accounting rules for removal pathways. They are not what most call ‘Methods’, but refer to existing accounting methods as indicated in the Guidelines and Accounting Stack. Each project or value-chain description should contain at least a description of the removal process, system, credit point, metric and MRV Protocol. This approach enables a rigorous yet fast and simple certification process.
Rigorous and scientifically based assessments
ISO standards established by the International Organization for Standardization in Switzerland, provide the basis for rigorous and scientifically based assessments. These include ISO 14064-1 (on the quantification of greenhouse gas emissions and removals) and ISO 14064-2 (providing project level guidance) and ISO 14064-3 (on validation and verification), ISO 14040 and 14044 (on Life Cycle Assessment), ISO 10694 (dry combustion method) and ISO 14235 (sulfochromic oxidation method).
What makes Oncra unique?
- Nature based removal only (as opposed to much plagued reduction credits)
- Measurement and data driven (as opposed to hard to prove modelling)
- Reputation safe (only sustainable buyers, no fossil companies)
Oncra is for carbon removal with natural pathways only. Oncra is based on measurements (unlike, surprisingly, most other carbon credit schemes that just estimate reductions). It is reputation safe, as it is the only removal accounting framework that only allows sustainable buyers (so excludes buyers with a fossil core business).
See the Oncra Guidelines for details.
