Which Milk Should I Choose?
Producing a glass of dairy milk every day for a year requires 650 sqm of land (two tennis courts), more than 10 times as much as the same amount of oat milk.
Oxford University has released a climate change food calculator for people to estimate the relative environmental impact of food choices.
A single glass of almond milk requires 74 litres of water to make, while rice milk requires 54 litres.
Dairy milk’s climate impact does however change by location and is lower in Oceania than other regions.
