The emotions of guilt and shame have an effect on how individuals feel and behave in relation to environmental crises, yet studies of the moral potential of these emotions remain limited. From a philosophical perspective, some scholars have defended using eco-guilt and eco-shame as morally constructive emotions due to their ability to evoke more pro-environmental behaviour. Meanwhile, others have posited that there are pitfalls to these emotions, claiming that they perpetuate a problematic individualised focus, which diverts attention from the collective (...) and structural conditions considered necessary for pro-environmental change. This paper critically examines these two differing perspectives on eco-guilt and eco-shame, applying insights from moral and political philosophy and the sociology of emotions. Through this exploration, we try to nuance the discussion concerning the moral potential of eco-guilt and eco-shame. We argue that if individuals are able to break their introspective, consumption-based loops of eco-guilt and eco-shame alleviation, the emotions may enforce an individual ethical demand to be more sustainable and foster an ethical and political pro-environmental drive. Furthermore, experiences of eco-guilt and eco-shame have the potential to spread socially and help catalyse emotional shifts within society, sparking a greater political and social pro-environmental movement. Therefore, eco-guilt and eco-shame may indeed transcend the purported introspective and individual-level focus and have the potential to influence broader collective and structural conditions and thus foster environmental change.
