In contemporary theological reflection, environmental issues have acquired a central and systematic relevance. From the perspective of religious traditions, the ecological crisis affecting the globalized world is increasingly interpreted as the manifestation of a deeper anthropological crisis, intrinsically connected to the diffusion of a "culture of waste" and to prevailing economic paradigms. Within this interpretative framework, religious actors have progressively assumed a direct and explicit responsibility with regard to environmental concerns, as clearly evidenced, within the Catholic tradition, by Pope Benedict XVI's encyclical Caritas in veritate and Pope Francis's encyclical Laudato Si'. The paper explores the contribution of faith-based actors to the development of innovative legal instruments aimed at strengthening the protection of natural ecosystems and promoting forms of shared governance of environmental and natural resources, including through structured modes of cooperation with public institutions. Particular emphasis is placed on the concrete engagement of religious denominations in fostering the transition towards sustainable economic models, highlighting how, in specific sectors, the alignment of production standards with religious dietary norms may contribute to the reduction of the environmental footprint of economic activities. Finally, the contribution examines the role of interreligious dialogue as a mechanism for the prevention, mediation, and resolution of disputes arising from the management of scarce natural resources, which are increasingly recognized as a major source of political instability and armed conflict. From this perspective, the involvement of faith-based actors emerges as a significant factor in processes of legal innovation and in the construction of sustainable and inclusive governance frameworks for natural resources.
