ONCRA is an Open Natural Carbon Removal Accounting framework, enabling removal and storage of carbon dioxide with nature-based solutions.
The accounting framework for carbon credits with nature-based solutions.
ONCRA stands for Open Natural Carbon Removal Accounting. ONCRA facilitates removal credits for nature-based solutions. Credits are issued based on measurements and open empirical crediting methodologies. ONCRA exists to foster distributed scaling of natural carbon removal towards gigaton scale, by simplifying assessments, reducing the cost threshold and expanding the scope of removal pathways.
In addition to existing protocols for Land Stored Carbon, Oncra offers new sectoral accounting protocols for Construction, Ocean and Rock Stored Carbon to push innovation in the carbon removal sector.
A reputation safe approach for the world’s best buyers
ONCRA Carbon Removal Credits are not just carbon credits. ONCRA performs a ‘doughnut check’ on the projects, evaluating co-benefits like biodiversity, clean water and meaningful jobs. ONCRA credits represent projects with ‘multi-potent’ benefits, ticking several Sustainable Development Goals (SDGs). Read more about Doughnut Economics.
Credits are issued for carbon removal based on measurements. ONCRA requires all procedures and measurements to follow ISO standards. 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). All data is openly accessible.
We require buyers to adhere to the Oxford Offsetting Principles. The Oxford Offsetting Principles were established to reduce risks associated with existing offsetting schemes.
