Who are we:

Grassroots Carbon Public Benefit LLC, is building the #1 grasslands soil carbon storage company.

Leading companies like Microsoft, Marathon Oil, HEB, Shopify, and Nestle have selected Grassroots Carbon to reach their carbon reduction goals.

Grassroots Carbon offers ranchers additional revenue opportunities via our carbon credit program. We support farmers and ranchers to manage their land for healthy soils, which store more carbon and improve water quality and biodiversity.
