Nori is a Seattle-based company that operates a blockchain-based marketplace connecting carbon removal suppliers with buyers worldwide. The platform enables farmers to remove carbon from the atmosphere through sustainable farming practices, which is then quantified and verified by an independent third party before being listed in the marketplace. Buyers can purchase ownership of carbon removals and receive a certificate for the same, allowing businesses and individuals to take direct action in removing excess carbon dioxide from the environment. Nori's mission is to remove enough carbon dioxide from the atmosphere to lower the overall concentration of CO2 below 300 parts per million, and they offer a maximally efficient method of coordinating the financial incentives of all parties involved in reversing climate change.
