Calculating Perfect Day's Potential Impact

According to the Food and Agriculture Organization of the United Nations, the United States produces 97,787,000 tonnes of milk, excluding butter.

If US consumers switched entirely to Perfect Day whey protein as a protein source from milk (assuming a 3.3% protein content of milk), this would result in avoiding up to 246 million tonnes of CO2e emissions, which is up to 28 million homes’ energy use for one year according to the US EPA Greenhouse Gas Equivalencies Calculator.

According to studies 1 and 2, the same amount of milk would require 32% of the total lighting energy consumed by US residential and commercial sectors and the amount of water needed by 187 billion people for the daily indoor home use. Therefore, deriving non-animal whey protein from Perfect Day rather than bovine dairy would lead to a reduction of approximately 18,600 billion gallons of water and 75 billion MJ energy use. For the purposes of these numbers, we calculated 5% of these numbers.
