About Us
Nori is the world’s only carbon dioxide removal marketplace. We are building a transparent and secure platform that will allow anyone in the world to pay to remove excess carbon dioxide from the atmosphere. Our voluntary marketplace will enable carbon removal suppliers to connect directly with buyers, improving efficiency and reducing costs.

Our Mission

We are reversing climate change

Nori is on a mission to reverse climate change. Our goal is clear: create a new way for anyone in the world to pay to remove excess carbon dioxide from the atmosphere.

Ramez Naam

Ramez Naam is a computer scientist, investor, and award-winning author of five books, including The Infinite Resource: The Power of Ideas on a Finite Planet, which charts a path to innovating our way beyond the challenges of climate change, ocean destruction, food, water, energy, population, and more.

Ramez is the Co-Chair for Energy and Environment at Singularity University at NASA Ames. He speaks around the world on innovation, exponential technology, solving environmental challenges, and disruptive energy technologies.

Ramez’s seminal 2011 Scientific American article, “Smaller, Cheaper, Faster” observed that the price of solar power was dropping exponentially and would eventually be lower than that of any other energy source. He’s since detailed the exponential trends in wind power, energy storage, and electric vehicles. His observations have been quoted by Nobel laureate Paul Krugman and by energy, climate, and financial analysts around the world. Ramez’s work has appeared in or been quoted in The New York Times, The Wall Street Journal, The Economist, The Atlantic, Slate, Business Week, Discover, Wired, and Scientific American.

In addition to his energy analysis, Ramez is an angel investor in numerous clean energy startups, a board member of E8 Angels, and the founder and leader of the first AngelList syndicate devoted to clean technology.


Each week, Nori offers insights and shares success stories on how removing excess CO2 from the atmosphere is impacting our climate, and details on our marketplace progress and buildout for launch.
