Abstract In this Opinion Paper, we argue that the absence of animal welfare in the United Nations’ sustainable development goals (SDGs) may not be as detrimental as some suggest. We put forward the view that the welfare of animals is an integral part of the concept of sustainability, that development which affects animals cannot be sustainable without due consideration to their welfare, and we give examples in support of this position. Put simply: no mention means animal welfare could be, and potentially should be, anywhere and everywhere in the goals. For livestock species, we submit that the synergies between the SDGs when animal welfare is included greatly outweigh the conflicts usually highlighted. Further, considering animal welfare as both an achievable goal and as a mechanism for sustainable development allows improvement of animal welfare to carry the weight it warrants: an animal with poor welfare is not a sustainable animal. By extension, products from animals with poor welfare cannot be considered sustainable, and animal welfare is necessarily included in a well-functioning ecosystem. Through the paper we argue that the challenge is not to add in animal welfare, but to think sustainability with animal welfare. We conclude by giving directions to where animal welfare can be integrated when developing sustainable actions.
