Excessive consumption of animal-based protein has led to a significant negative impact on the environment and human health. Companies producing alternative protein end-products aim to produce substitute products that are similar to conventional animal-based products with less environmental impact. In this research, 955 alternative protein companies were analyzed using descriptive methods. The results revealed a significant increase in the number of companies after 2015, indicating high industry potential and an increasing global focus on sustainability. Plant-based products dominated the production structure because they were more appealing to consumers and may reach price parity sooner. Current food systems are unsustainable. Thus, although some factors still hinder the market uptake of alternative proteins, a shift towards a more sustainable food system is inevitable in the future.
