Animal-Free Milk Generates 96% Fewer Emissions Than Dairy

A Life-Cycle Assessment conducted by an independent third party has concluded that a market participant’s animal-free milk uses significantly fewer natural resources than cow’s milk and has a much smaller environmental footprint.

The milk is made with animal-free whey and casein, which are produced using precision fermentation. The LCA compared one liter of animal-free milk made with the manufacturer’s whey to an equivalent amount of dairy milk that had the same amount of protein.


The results show that the whey milk generated 96% fewer emissions than cow’s milk, while using 99% less water, 92% less land, and 50% less energy. It is believed that the animal dairy sector is responsible for 2.7% of global greenhouse gas emissions — more than aviation. Consequently, a shift to animal-free dairy could have huge environmental implications.

It is considered that if just 5% of the milk produced in Europe was replaced with animal-free dairy, it would save the equivalent of the amount of electricity used by Paris in 20 years, along with 2.3 million Olympic swimming pools of water and the amount of fuel required to travel around the world 660,000 times.
