Nori (company)

Nori serves as an open-source, blockchain-based marketplace where those providing carbon offsets, called suppliers, provide information on their verified carbon removal process and sales of carbon offset units. Nori was founded in 2017 by Paul Gambill, Ross Kenyon, Aldyen Donnelly, and Christophe Jospe.

Nori provides a marketplace for commodified carbon offset projects. Nori carbon offsets are focused exclusively on the removal of existing carbon in the atmosphere, and not the prevention or decrease of future emissions. As of early 2022, Nori's offered projects are solely ones that sequester carbon in soil. Each carbon offset project and its supplier is evaluated by an independent third party that verifies its authenticity. Using blockchain technology, carbon offsets are purchasable in the form of NRTs, or Nori Removal Tonnes. The purchase of one NRT is equivalent to the removal of one metric ton of CO2e, stored for a minimum of ten years. Each purchase of an NRT is marked with a digital ownership certificate detailing the amount of carbon removed and where it was stored. Nori uses the carbon quantification tool Soil Metrics to model carbon baselines off of supplier data. This is used to calculate the amount of NRTs available for purchase from a supplier, based on a fair pay model. The purchase cost of one NRT, as of February 2022, is $15 plus a 15% site fee.
