Metrics In Development

Three metrics are currently in progress:

  • Greenhouse Gas
  • Simple Irrigation Effiiciency

Highlights are below; for additional information, please login at left.

Greenhouse Gas (GHG)

The GHG Metric addresses the GHG emissions associated with five components:

  1. fuel use;
  2. electricity use;
  3. fertilizer production;
  4. N2O emissions; and,
  5. soil C storage.

The metric was challenged by which tool to use to account for the N2O and soil C components. Ultimately, the Cool Farm Tool was proposed for both N2O and soil C. Of the concerns raised in the technical review, many were addressed in a response by the developers of the Cool Farm Tool. At this point, completing the metric requires a decision about whether to proceed with the Cool Farm Tool and other details surrounding that decision.

Draft Metric

Tons CO2e / Tons harvested

Simple Irrigation Efficiency

The Simple Irrigation Efficiency (SIE) metric measures how efficiently irrigation water is used to meet a crop's water demand. A grower can improve the SIE metric score by reducing losses of water to pathways that don’t contribute to crop growth, including soil evaporation, percolation and run-off.  As such, the SIE metric is an indicator of how productively the water resource is being used. 

Draft Metric

Volume of applied irrigation water / ETc  (volume of water used through crop evaporation and transpiration) 

SISC Vision

SISC's founding vision was ambitious: to develop a system for measuring performance throughout the specialty crops supply chain—from farm to plate. Based on the direction of current participants, the first five Working Metrics focus more narrowly on on-farm resource use. Still, SISC leadership remains committed to developing metrics that address performance across the supply chain, and/or to join other metrics-driven initiatives seeking to do so.

1. includes related water quality issues
2. includes health and safety of workers and communities
3. includes stormwater runoff and process water
4. improved efficiency/cost reduction will be incorporated into other metrics where appropriate
