The staggering truth is that what's on our dinner plate has a monumental environmental footprint, with livestock contributing a massive 14.5% of global greenhouse gas emissions and consuming over a quarter of our planet's freshwater.
Key Takeaways
- Livestock supply chains emit 7.1 gigatons of CO2-equivalent annually, accounting for 14.5% of global anthropogenic greenhouse gas emissions

- Enteric fermentation from ruminants contributes 39% of livestock sector's GHG emissions, primarily methane
- Producing 1 kg beef requires 15,000 liters of water, compared to 4,300 for pork and 3,000 for chicken
- Global livestock sector consumes 29% of total freshwater withdrawals, 8% of global freshwater use
- Beef water footprint: 15,415 liters per kg, 51% green water from rain
- Livestock occupies 77% of agricultural land but provides 18% of global calories and 37% protein
- Pastureland for grazing covers 3,440 million hectares globally, 26% of ice-free land
- Feed crops for livestock use 1,033 million hectares, 36% of cropland
- Deforestation for cattle pasture in Amazon: 80% of clearing, 20,000 km2/year
- Livestock farming drives 14.5% of global deforestation
- Brazilian Amazon beef: linked to 91% forest loss 2000-2015
- Global manure production from livestock: 13 billion tonnes dry matter annually, polluting waterways
- US hog farms generate 500 million tons manure yearly, equivalent to human waste of 9 billion people
