Dairy Production
Global dairy production reached ~960 million tonnes in 2024 — a four-fold increase since 1960. India is the world's largest producer at ~230 Mt, mostly buffalo and cow milk. The EU follows at ~155 Mt, USA at ~103 Mt. Dairy is the largest single source of agricultural methane after rice; production efficiency varies 5× across regions, with major room for emission reduction at constant output.
Key insights
India dwarfs other producers in volume
India produces nearly a quarter of world dairy. Production is dominated by smallholder farmers with 2-10 cows or buffalo. White Revolution (1970s-onward) and Operation Flood transformed Indian dairy through cooperative organization (Amul, Anand pattern). Per-capita Indian dairy consumption is the world's highest. Buffalo milk (richer in fat) is the dominant product in India vs cow milk globally.
Yield per cow varies enormously
US Holstein dairy cows produce ~11,000 kg/year on average. EU averages ~7,500 kg. India: ~1,500 kg (smallholder, low-input). Sub-Saharan Africa: ~600 kg. Yield differences reflect genetics (Holstein breeding), feed quality (corn silage + grain), housing, veterinary care. Higher yield per cow = lower emissions per kg of milk; but high-yield systems require more inputs and concentrate environmental impact.
Dairy alternatives are growing but small
Plant-based milk alternatives (oat, almond, soy, pea) reached ~$30B global market in 2024, ~3% of total milk-and-alternatives market. Oat milk has been the fastest grower since 2015 (Oatly, Califia, Chobani). Almond milk has water-use concerns; soy faces broader anti-soy sentiment. Cellular dairy (lab-grown casein via precision fermentation: Perfect Day, Remilk) is technically promising but pre-commercial at scale.

Methodology & caveats
Dairy types
Dairy includes cow milk (~80%), buffalo milk (~14%), goat milk (~3%), sheep milk (~1.4%), camel and other (~1.6%). India and Pakistan lead in buffalo milk; goat milk is concentrated in South Asia and Sub-Saharan Africa. Different products serve different markets and have different processing characteristics.
Climate footprint
Dairy is among the highest-emission animal proteins per gram of protein delivered: ~10 kg CO₂eq per kg of milk in intensive systems; up to 40 kg CO₂eq per kg in extensive smallholder systems. Emissions come from: enteric fermentation (cow burps, ~40-60%), manure management (~20-25%), feed production (~15-25%). Bovaer feed additive can reduce enteric methane 30%+; other solutions are emerging.
Trade
Most dairy is consumed domestically; only ~7% of global production is internationally traded. Powdered milk, butter, cheese trade more readily than fresh milk. The EU and New Zealand together account for ~50% of world dairy exports. China is the largest single importer. Trade flows can shift rapidly with disease outbreaks (FMD, avian flu in dairy cattle) or policy changes.
