Our research discusses how four main ethical challenges to veganism manifest in the context of Iceland. Veganism is becoming an increasingly popular lifestyle in many parts of the world, especially in OECD countries. Studies on the motivation for choosing a vegan lifestyle (which includes, but is not restricted to, following a vegan diet) include ethical considerations, dietary choices, personal health, taste, religious and political beliefs, or environmental concerns. Ethics plays a particularly important role, and as such, veganism has become a (...) central object of interest in recent conversations on animal rights and welfare among ethicists. Our analysis reviews four ethical challenges (i.e., the challenge of universality, demandingness, causal impotence, and the least environmental harm principle) in the literature that problematize the norms and rationale underpinning veganism and vegan discourse and discusses how each applies within the context of Icelandic society and geography. We conjecture that the particular economic, demographic, and geographic characteristics of Iceland indicate that being vegan in Iceland does not free oneself of having global social and environmental impacts on account of chosen dietary options. All diets constitute global systems that account for dependencies and opportunities, vulnerabilities, and strengths, which may challenge the assumption that veganism is a more socially and environmentally sustainable dietary option within this particular regional context.
