Cellular agriculture, producing cultured meat and microbial proteins, aims to enhance food security. This study uses a global dynamic model and life-cycle assessment to analyze scenarios replacing traditional livestock products with cellular agriculture from 2020 to 2050. Findings suggest a transition could reduce annual greenhouse gas emissions by 52%, phosphorus demand by 53%, and land use by 83%. However, it increases demand for critical materials, with tellurium being the main exception due to production capacity limitations. The study concludes that a transition is environmentally beneficial but requires careful consideration of critical material demands.
