Soil Enrichment Protocol

The Soil Enrichment Protocol (SEP) provides guidance on how to quantify, monitor, report, and verify agricultural practices that enhance carbon storage in soils. The primary GHG benefit targeted is the accrual of additional carbon in agricultural soils, with hopes to incentivize GHG emission reductions from other sources, such as N2O from fertilizer use. The protocol was adopted by the Reserve Board of Directors in September 2020.
