Isometric's New Soil Management Protocol Raises Quality Standards for Soil Carbon Removal
carbonherald.comIsometric has certified a new Improved Soil Management Protocol that sets stricter rules for measuring and verifying carbon dioxide removal from soil. The protocol requires direct soil sampling, accounts for all greenhouse gas emissions, and mandates a minimum 20% revenue share for landowners. This aims to increase buyer trust and scale soil-based CDR, which could remove up to 430 million tonnes of CO2 per year globally. Three major project developers have already registered under the protocol, including Great Yellow in the UK, Cultivo in US grasslands, and HGX working with over 1,000 US farmers. Isometric's Certify platform uses AI to speed up certification and verification. The protocol addresses a key barrier in voluntary carbon markets: ensuring that soil carbon credits represent real, durable removals rather than inflated estimates.
