Abstract:The life cycle assessment （LCA） was employed to comprehensively calculate the total and per-unit carbon emissions of five plant-based meat products [artificial beef patties （BPa）,artificial pastrami slices（PSa）,artificial sliced ham （SHa）,artificial stewed meatball （SMa）,and artificial crispy cutlets （CCa）].The results were then compared with the carbon emissions from the corresponding farmed meat products.The results demonstrated that the total carbon reduction of the five plant-based meat products were 45.20,34.06,3.61,3.23,and 2.87 kg CO2e,respectively,with an average reduction effect exceeding 78%.The total carbon emissions （TCE） of the five plant-based meat products were significantly lower than those of farmed meat products.Additionally,the unit carbon emissions （UCE） generated during the raw material acquisition phase were greater than those in the production,processing,and distribution stages of both artificial and farmed meat.The UCE in the raw material acquisition phase of plant-based meat was mainly from other materials,plant protein production,and fertilizer use,while that in farmed meat primarily stemmed from feed emissions.In summary,replacing farmed beef with plant-based meat achieved the most significant carbon reduction.Further carbon emission reduction in natural meat production can be achieved by improving farming practices,altering feed types,and advancing manure treatment technologies.
