Meat induces large environmental impact while supplying important nutrients, and meat substitutes are increasingly adopted as direct replacers of meat products. This study assessed the environmental impact of a pork schnitzel and two soy-based schnitzels in terms of three different functional units to reflect the products’ functions as meal components and suppliers of high quality proteins. For a functional unit of 1 kg of product, the pork schnitzel induces the largest environmental impact for most environmental impact indicators.
