Our Environmental Indicators

Eight Environmental Indicators Continuously Reviewed and Based on the Latest Science

Field to Market’s program centers on eight environmental indicators that measure environmental impacts on individual fields. These indicators are built into the Fieldprint Platform® and developed through a multi-stakeholder process, including the Metrics Committee.

These indicators are reviewed regularly to ensure they remain current, useful, and grounded in the latest science.

What each indicator measures, why it matters, and how it’s calculated

Biodiversity

Field-level habitat potential based on land cover and management practices.

Biodiversity

Field-level habitat potential based on land cover and management practices.

The Fieldprint Platform measures field-level biodiversity using the Habitat Potential Index (HPI), a scoring system developed by Field to Market in 2014. The HPI evaluates how well a field supports habitat based on management practices like crop diversity, tillage intensity, and integrated pest management, among others.

Scores range from 0-100. A low score suggests significant opportunities for habitat improvement, while a high score indicates the field is already well-positioned to support biodiversity.

Grain
Energy Use

Cradle-to-processing-gate energy demand associated with crop production.

Energy Use

Cradle-to-processing-gate energy demand associated with crop production.

The Energy Use indicator estimates the cumulative energy demand (CED) associated with producing a given crop, following a cradle-to-processing-gate system boundary. The CED accounts for the primary energy, from fossil and non-fossil sources, and used throughout the life cycle, including upstream supply chains. In the Fieldprint Platform, Energy Use can be expressed as the sum of three components:

  • Upstream: Energy use associated with electricity generation and distribution, transportation of agricultural inputs, and production of fuels, fertilizers, pesticides, and seed.
  • On-farm mechanical: Energy use associated with mobile and stationary machinery on-farm, such as tractors, combines, and irrigation pumps.
  • Post-harvest: Energy use associated with mobile and stationary machinery outside the farm, such as crop transportation and drying.
Combine
Greenhouse Gas Emissions

CO₂, CH₄, and N₂O emissions associated with producing a given crop, using international standard models and factors.

Greenhouse Gas Emissions

CO₂, CH₄, and N₂O emissions associated with producing a given crop, using international standard models and factors.

The GHG Emissions indicator in the Fieldprint Platform estimates emissions associated with producing a given crop, converting greenhouse gases to Global Warming Potential (GWP) using the IPCC Sixth Assessment Report's 100-year time horizon factors.

The indicator follows a cradle-to-processing-gate system boundary and supports separating emissions by gas type (CO₂, CH₄, N₂O). The indicator is expressed as the sum of the four components below, which encompass all major emission sources in row crop production:

  • Upstream: Emissions associated with electricity generation and distribution, transportation of agricultural inputs, and production of fuels, fertilizers, pesticides, and seed.
  • On-farm mechanical: Emissions associated with mobile and stationary machinery on-farm, such as tractors, combines, and irrigation pumps.
  • On-farm non-mechanical sources and sinks: Emissions associated with eight soil processes, such as nitrous oxide, direct land use change, CO2 from urea, and soil organic carbon fluxes (which can be a source or a sink), and emissions from inputs such as lime and urea fertilizers.
  • Post-harvest: Emissions associated with mobile and stationary machinery outside the farm, such as crop transportation and drying.
Irrigation
Irrigation Water Use

Amount of water applied to achieve an increase in crop yield compared to non-irrigated conditions.

Irrigation Water Use

Amount of water applied to achieve an increase in crop yield compared to non-irrigated conditions.

The Irrigation Water Use (IWU) indicator is expressed as the amount of irrigation water required to produce one unit of additional crop output compared to non-irrigated conditions. Lower IWU values indicate more water-efficient irrigation practices, as less water is needed to produce each additional unit of crop output.

Fields
Land Use

Land footprint efficiency relative to crop production outcomes.

Land Use

Land footprint efficiency relative to crop production outcomes.

The Land Use indicator quantifies agricultural intensity by measuring the land area required to produce one unit of crop output. Expressed as area per crop production unit, such as acres per bushel for grains or acres per pound for crops like cotton and peanuts, this indicator provides insight into how intensively land resources are being utilized.

Lower values indicate greater land use intensity, meaning less land is needed to produce each unit of output, which is a key consideration as agricultural systems balance productivity with environmental stewardship.

Soil
Soil Carbon

Quantitative soil carbon outcomes modeled to support an understanding of carbon stock changes.

Soil Carbon

Quantitative soil carbon outcomes modeled to support an understanding of carbon stock changes.

The Soil Carbon indicator provides a quantitative assessment of annual soil carbon stock changes from consecutive calendar years for a field boundary for the top 30-cm of the soil profile. This indicator uses SWAT+ (Soil and Water Assessment Tool Plus), a robust Tier 3, process-based model that simulates carbon dynamics across multiple soil carbon pools.

The model accounts for how management practices influence carbon flows between these pools, incorporating factors such as tillage intensity, crop rotation diversity, cover cropping, nutrient applications, residue management, and organic matter additions. This approach allows farmers to assess how management changes can enhance soil carbon sequestration over time, supporting both climate mitigation goals and long-term soil health.

Crops
Soil Conservation

Estimation of modeled soil losses tied to management, soil types, and erosion processes.

Soil Conservation

Estimation of modeled soil losses tied to management, soil types, and erosion processes.

The Soil Conservation indicator is a comprehensive measurement that quantifies soil lost to erosion from water and wind in agricultural landscapes. Reported as tons of soil lost per acre per year, this indicator helps farmers understand and address soil erosion. The Soil Conservation indicator utilizes two powerful process-based models developed and maintained by USDA: the Water Erosion Prediction Program (WEPP), and the Wind Erosion Prediction System (WEPS).

Water Quality

Potential impacts on water resources driven by nutrient losses.

Water Quality

Potential impacts on water resources driven by nutrient losses.

The Water Quality indicator leverages the Stewardship Tool for Environmental Performance (STEP) developed by USDA. STEP evaluates the potential for nutrient losses from agricultural fields based on site-specific soil, topographic, and climate conditions. STEP assesses four nutrient loss pathways: nitrogen and phosphorus lost in surface water runoff and nitrogen and phosphorus lost to subsurface leaching. STEP is an index tool that determines field-specific risk levels and evaluates how management practices mitigate those risks.

This approach offers insights into loss pathways and targeted improvement opportunities, allowing farmers and supply chain partners to identify the most effective practices for water quality improvement in their regions.


Our Scientific Foundation

Indicators Vetted and Implemented Through Transparent, Multi-Stakeholder Governance

Field to Market’s Metrics Committee oversees these eight environmental indicators, with elected representation across membership sectors. The committee regularly reviews each indicator to ensure the scientific models, tools, and impact factors remain current and useful, as well as to keep the Fieldprint Platform aligned with evolving needs across the value chain.

We prioritize method transparency. Explore the public documentation for how indicator values are created and reported in the Platform.
