Decarbonizing poultry: emission hotspots and FLAG levers

Poultry is one of the most widely consumed proteins globally. Per kilogram, chicken meat has a carbon footprint about 90% lower than beef from beef herds and about 75% lower than lamb ( Poore and Nemecek, 2018 ). Scale makes emissions management critical: about 77 billion chickens were slaughtered for meat in 2023 ( FAOSTAT via Our World in Data ).
