On players, coaches, referees, and the audience: a sports metaphor for rule-writing to address climate change.

Warning: this is a long post with many layers of metaphors. Michael Lewis’ podcast “Against the rules” inspired me to write this. He is one of my favorite storytellers who artfully weaves together tales…

I write this for my former self. Someone who upon learning about decarbonization innovations would have his brain screaming “Deploy! Deploy! Deploy! Scale! Scale! Scale!” It still sometimes does. But now I’m aware of this carbon exuberance


To some who know me, it may come as a shock that I’m moving on from Nori, a start-up I co-founded, that is making it possible to get paid for pulling carbon dioxide out of the atmosphere a.k.a. “carbon removal”. It’s not an easy decision. I’m immensely grateful to all…


Nori is in the business of incentivizing carbon removal. We do this by issuing sellable Nori Carbon Removal Tonnes (NRTs) to “Suppliers”, who are initially US food and fiber producers and have adopted new practices that remove carbon. In the past, we’ve written about how Nori generates a supply of…


What I’m stewing on

Living in Tennessee for the month of February was transformative. I was in town for AgLaunch, a program to help start-ups who are bringing new technologies to row crop agriculture. I had some fun road trips, got to sit in on drums in a few blues jams, and realized how…


In the past, I’ve written about how Nori compares to other climate start-ups and blockchain plays, and how Nori compares to traditional carbon markets. This article is for anyone considering selling carbon removal services in the Nori market, and comparing it to other options.

What is an ecosystem service?

“Ecosystem service” is the term to…


The why, what, and how of a monthly newsletter from an entrepreneur on a mission to reverse climate change

This year, I’m restarting a newsletter.

In the summer of 2016, when I left a dream job as chief strategist at the Center for Negative Carbon Emissions at Arizona State University, I started a mailing list as part of my new company called Carbon A List. It was a way…


This article is written for the layperson who is trying to understand soil organic carbon (SOC) quantification. It is long and gets into the weeds. …


Last month, Nori graduated from the Techstars Sustainability Program. The program is a 14-week long intensive accelerator for start-ups working on “viable technologies that can rapidly scale to help sustainably provide food and water and address global issues like climate change.” It represents a partnership between The Nature Conservancy and…


It’s been two years of a lot of hard work, but I’m proud to finally say that Nori has passed an important milestone. We've finally created a way that allows any individual or business to buy carbon removal. Now anyone in the world can pay to pull carbon dioxide out…
