Carbon Sage · ✦
Soil-organic-carbon stock, sequestration headroom, low-emissions forage, county-level rollups for insetting. Cited to USDA SSURGO, RAP 2025 vintage, and NASS · spine-native at parcel and county resolution.
TRY THIS SAGE
USDA SSURGO + RAP + NASS rollup · returns the top-ranked county for cattle carbon insetting in that state
01
What it knows
Soil organic carbon stock
gNATSGO 0-100cm SOC, banded low/moderate/high at parcel resolution and rolled up by county.
Forage productivity
USDA RAP 2025 vintage, weekly-averaged into per-parcel lbs/ac · the substrate for enteric/methane modelling.
Headroom composite
Score out of 100 per county · weighted blend of ag fraction · SOC stock · forage productivity. Returns a tier (low/moderate/high).
Ag-class filter
USDA CDL land-class filter so cropland / pasture / hayland gate in, and developed / open-water / forest gate out.
Animal-aware ranking
Grazing-ecology model picks which land-class fits cattle vs goats vs sheep vs bison · re-ranks the same substrate by animal.
02
Authoritative sources
Every Carbon fact ships with a source · vintage · confidence. The composite is a cited weighted blend, not an opaque score · methodology is queryable at /api/carbon/methodology.

County rollups are CONUS-national from USDA NASS + gNATSGO + RAP. Per-parcel deep-dive lights up where the spine has been attributed; each new state added to Land brings parcel-level carbon ranking with it.
