The primary ingredient in most ice creams is dairy, and the production of milk has significant environmental implications. Dairy farming is a major contributor to greenhouse gas emissions, particularly methane, which is released by cows. Methane is a potent greenhouse gas, with a warming potential many times greater than carbon dioxide.

Additionally, the resources required for dairy production—including water, land, and feed for cows—intensify its environmental footprint. A single liter of milk requires approximately 1,000 liters of water to produce, making ice cream a water-intensive treat.
