What We Do

Many companies face ambitious climate targets. They need to reduce their own emissions and remove CO2 from the atmosphere by purchasing high-quality carbon credits. Meanwhile, American ranchers occupy hundreds of millions of acres of grazing lands that can draw carbon down and store it in soil for thousands of years.

Grassroots Carbon partners with ranchers across the United States to help them get rewarded for storing carbon by matching them with corporate carbon credit buyers.

We arrange rigorous soil sampling and measurement to assess carbon storage on their land, provide education on the best land management practices for carbon storage, verify and certify the carbon credits according to the Regenerative Standard, and find buyers for the credits.

How It Started

Grassroots Carbon was founded as a nature based voluntary carbon marketplace to provide benefits to ranchers while helping companies reduce their carbon impact. Here’s how it started.

Dr. Henk Mooiweer co-founded Soil Value Exchange Public Benefit LLC, a carbon crediting aggregator that delivers high-quality, measured, and independently certified soil carbon storage.


PastureMap, a grazing management software company founded in 2015, was acquired by Soilworks Natural Capital, an investment company on a mission to prove that regenerative grazing is the most profitable way to ranch.

April 2021

PastureMap and Soil Value Exchange merged to form Grassroots Carbon Public Benefit LLC, becoming a Soilworks Natural Capital portfolio company.

January 2022

Grassroots Carbon issued America’s first soil carbon credits and disbursed the first payments to ranchers.

January 2023

Grassroots Carbon continues to rapidly grow and has paid ranchers over $2 Million for storing carbon, with over 20 carbon credit buyers.
