Meat production rose 1.1% year over year in 2023, but the counterpoint is just as hard to ignore: 51.4 billion head of poultry were slaughtered globally in 2022. From EU stunning rules and inspection intensity to the downstream pressure on ammonia emissions, energy use, and worker safety, these slaughterlinked figures connect animal handling to public health, climate, and waste.
Key Takeaways

- 70–90% of freshwater eutrophication potential impacts for meat supply chains occur upstream in feed production (review paper)
- 2.1 kg CO2e per kg of poultry meat produced (life-cycle assessment; slaughter/processing included; review)

Market And Production2 stats
01
41.6 million tonnes of global meat production in 2022 (all meats) implies a large processing footprint for slaughter/processing capacity, based on the World Bank “Livestock and Meat” data series aggregation.
02
12.4% of global poultry meat production was exported in 2022, indicating a high level of processing/slaughter-linked export flows.
Interpretation
Market And Production Interpretation
In the Market and Production frame, the World Bank data suggest that with 41.6 million tonnes of global meat produced in 2022 and 12.4% of poultry meat exported, slaughter and processing capacity are driven not just by domestic demand but by substantial international export-linked flows.
