Driven by a continuous rise in household living standards, China's meat consumption keeps growing, increasing the need for greenhouse gas (GHG) emissions mitigation. This study employed a process-based life-cycle inventory model to quantify the province-level GHG emissions of meat products in China. Four major livestock products (beef, mutton, chicken, and pork) at four farming scales (cage-free, small, medium, and large-scale farming) were considered. The GHG emissions of the Chinese livestock sector were 429 million tons (MT) CO2e in 2018. Beef had the highest GHG intensity (19.6 kg CO2e/kg), followed by mutton (10.0 kg CO2e/kg), chicken (4.4 kg CO2e/kg), and pork (3.8 kg CO2e/kg). Spatially, northwestern China had a high GHG intensity (5.58 g CO2e/kcal), while the eastern and central regions presented low-intensity values (1.89 and 1.71 g CO2e/kcal, respectively). At the...
