Some dairy farm teams are working with their milk coop , processor or advisor to develop a greenhouse gas (GHG) or "carbon" footprint. The footprint includes a GHG intensity score (emissions per unit of fat and crude protein-corrected milk) and an estimate of total GHG emissions (total emissions for the farm). What do these numbers mean and how can you make decisions based on the results of footprinting tools currently on the market? We believe that every dairy farm can benefit from developing a GHG footprint. Annual footprinting will help farmers keep their dairy business current as value chains increasingly ask for this information.
