The National Dairy Farmers Assuring Responsible Management Environmental Stewardship Program has announced updates to its Version 3 evaluation tool, incorporating the latest scientific advancements from the Ruminant Farm Systems, or RuFaS, model used to measure dairy sustainability practices. National Milk Producers Federation Chief Sustainability Officer Nicole Ayache said the updates will help dairy farmers better understand how management decisions affect their environmental footprint while identifying stewardship opportunities that also support business goals. “FARM Environmental Stewardship continues to adapt as science and technology advance within the dairy sector,” Ayache said. The revised tool now integrates homegrown feed production into a farm’s total environmental footprint to better account for field-level practices. Updates also improve scientific modeling tied to youngstock manure management and manure storage systems, including improved sensitivity to temperature impacts. Industry leaders said the program continues to provide dairy producers with science-based sustainability tools that work across different farm sizes, production systems, and geographic regions.
