What are the environmental impacts of vegan vs. meat-based pet diets? In Frontiers in Sustainable Food Systems, Billy Nicholles and Andrew Knight considered the meat- and plant-based ingredients within commercial pet foods, and the role of animal byproducts. They even considered emerging alternatives, including cultivated meat and microbial protein-based pet foods. The results are clear: sustainable pet food alternatives offer environmental benefits which are both massive and under-recognised. Full study: Nicholles B & Knight A (2025).
