COMET-Farm™ & COMET-Planner™

Calculation Methods

  • Implements the peer-reviewed, USDA-

sanctioned entity-level inventory methods.

  • Soil-related GHG emissions: DayCent dynamic

model, also used in the U.S. National Greenhouse Gas Inventory.

  • Livestock-related GHG emissions: statistical

models based on USDA and university research, largely consistent with models used in the U.S. National Inventory.

  • Energy-related GHG emissions: based on the

models used in the USDA/NRCS Energy Tool along with supplemental peer-reviewed research results.

Every 1% increase in organic matter on 160 acres with a silt-loam soil equals ~ 900 metric tonnes CO2e. This equals removing the emissions from ~190 passenger vehicles for 1 year.

Modeling Carbon Farming in COMET-PlannerTM and COMET-FarmTM

  • Cropland and grassland in Merced County featured in this analysis.
  • Results from COMET-PlannerTM and COMET-FarmTM are both shown.
  • This is NOT a model comparison exercise!
  • Results from both tools illustrate the effects of regional variability in

soils, climate and cropping practices.

  • COMET-PlannerTM: Use for Project Planning
  • COMET-FarmTM: Use for Field & Pasture-level Verification

Conclusions

  • This was NOT a model comparison exercise!
  • Results from both tools illustrate the effects of regional variability in

soils, climate and cropping practices.

  • Use COMET-PlannerTM for Project Planning
