Investor and carbon farmer Sallie Calhoun is on a mission: to change our relationship to the earth beneath our feet. After selling her tech company in 2001, she quickly became the proud owner of 7,600 acres of California grassland called Paicines Ranch — plus enough money to leverage some serious change. Now, along with impact investing guru Esther Park, she co-manages a soil-health portfolio called Cienega Capital with $20 million deployed to-date, and has recently co-founded the No Regrets Initiative to build momentum toward climate-beneficial communities. Why is Calhoun so committed to turning dollars into dirt? We sat down with her to learn more and find out.
Why is regenerative soil important?
In a closed environment (like our planet), matter is neither created nor destroyed. So as atmospheric carbon steadily increases (in December 2017, it passed 410 parts per million for the first time in millions of years), carbon levels must steadily decrease somewhere else — and that somewhere else is our global soils. To reverse climate change, carbon in the atmosphere must return to the soil, a process that green, photosynthesizing plants are already perfectly designed to execute.
