 Sustainability is generally associated to sustainable development, which is based on the three pillars model. These pillars are the social, environmental and economic ones. However, there have been increasing criticisms to this model, claiming that there is a fundamental element missing in it, culture. Cultural critiques to the three pillar model range from suggestions to include culture as the fourth pillar of sustainable development, to interpretations of the pillars as dimensions instead. In the dimensions approach, culture is perceived holding different roles, such as, culture in, sustainable development, in which it holds an independent, supportive and self-promoting role. Culture for, sustainable development, in which it works as a mediator among the other dimensions. And culture as, sustainable development, in which culture is an all-encompassing dimension, embracing all the other ones. Culture has also been explored, in diverse levels of, sustainable culture, cultural sustainability, and cultures of, sustainability. These levels are however, interdependent and interactive. Cultural cultures require cultural strategies for sustainability, in for example, media channels, to share the values of the cultures of sustainability. While cultures of sustainability, demand fundamental shifts in communication, for more inclusive cultural sustainability and sustainable cultures. The importance of these debates, is that, they indicate the complexity of culture, and how much of a role it plays, in the possibilities, of having a more sustainable world. They challenge ready-made models, that try to reach a universal standardized application, and claim for more integrative approaches, in connection to local cultures and expertise, which embrace various particular world views, value systems, and symbolic universes. In this sense, sustainability can be understood as, multiple processes of transformation, not stagnated in a model. It instigates self-reflexive cultural practices, and multiple understandings of development, not biased by economic standards of growth. It engages ethical practices, various forms of knowledge-making and sharing, and constant questioning, as its fundamental values. Due to its very transformative and processual qualities, culture might not provide a renewed model for sustainability. However, its importance lies exactly on challenging ready-made models, and demanding openness, and the practice of self-reflection.
