Sustainability In The Dairy Industry Statistics

Dairy’s climate impact is anything but fixed, with cradle to farm-gate estimates ranging from 0.93 kg CO2e to 1.0–1.6 kg per kg milk, while manure upgrades like anaerobic digestion can cut biogas methane potential by 70% versus baseline. See how 2025 proof points and reporting momentum are reshaping incentives, from CSRD and SFDR disclosure pressure to a 2023 market scale of USD 583.0 billion for dairy products and USD 58.1 billion for plant-based alternatives, plus the hard process reality that cooling and processing can drive 30 to 40% of total footprint in some LCAs.

Dairy accounts for 14.5% of global agricultural greenhouse gas emissions, yet its climate footprint can swing from 0.93 to 1.6 kg CO2e per kg milk depending on how farms are run. Add processing and cooling, which can make up 30 to 40% of the total carbon footprint in some life cycle assessments, and it becomes clear why “one number” rarely fits the sector.
