This project estimates and analyzes the global warming potential emissions from three dairy production systems in Iowa: grazing, combination grazing/conventional and conventional. A cradle-to-farm gate Life Cycle Assessment is performed for these three systems with milk production as the reference flow.
Which alternative dairy produced the lowest greenhouse gas emissions?
Knowing this will help dairy farmers choose the most profitable system that is suited to their goals and resources, and they also can consider greenhouse gas emissions in their decision. Farmers are concerned with greenhouse gas emissions and their contribution to global warming. They know that if they are not proactive in their approach to production, there will be regulations that might not be favorable.
