The CaRPE Tool

The Carbon Reduction Potential Evaluation Tool

The CaRPE Tool

The CaRPE Tool lets users quickly visualize and quantify net GHG emission reductions.

The Carbon Reduction Potential Evaluation Tool™, or CaRPE Tool, is a web-based interactive tool that allows users to quickly visualize and quantify greenhouse gas, or GHG, emission reductions resulting from the implementation of a suite of cropland and grazing land conservation management practices. 

The CaRPE tool expands the utility of the data reported by COMET-Planner by layering cropland and grazing land acres data from the 2017 Census of Agriculture

The tool provides a mechanism to quickly compare practices, their estimated costs, and where the greatest impact can be achieved across a state or region. The tool’s data and maps help policymakers and land managers prioritize efforts for cost-effective optimal climate benefits from agricultural management.

Dr. Jennifer Moore-Kucera, AFT’s climate initiative director, created this tool as part of the Farmers Combat Climate Change initiative.

More Information about the CaRPE Tool™

The CaRPE Tool helps states seize carbon in agricultural lands.
What can you do with it?
  • Map current acres and percent of cover crops and conservation tillage at county scale.
  • Estimate (and map) GHG reduction potential from current adoption levels.
  • Run scenarios for future GHG benefits from additional acres implementing practices.
  • Estimate implementation cost using state average EQIP rates or user-defined costs.
  • Generate maps and tabular data summarized for each scenario and scaled to county, state, regional, or national levels.
How many crop and grazing land practices are available?
  • Seven cropping system management categories with multiple selections (e.g., reduced till, no-till and legume and non-legume cover crops) and a cover-tillage-nutrient combination option.
  • Four grazing land management categories with multiple selections for nutrient management category.
Who is the tool designed for?
  • State policymakers, Soil & Water Conservation District planners, state and federal conservation agencies, NGOs, etc.

The CaRPE Tool was developed in collaboration with Dr. Daniel Manter, USDA-ARS Soil Scientist and funded in part by The Nature Conservancy, The Ida and Robert Gordon Family Foundation, and members of American Farmland Trust.
