Mining relates to violence in diverse ways, and frequently the relationship includes environmental violence. New technologies, including those central to a clean energy transition, mean that mining will remain a necessary industry. This means in turn that the human community will remain in need of ways to minimize and cope with the environmental violence of mining. The theory and practice of Catholic peacebuilding can offer distinct resources for dealing with these challenges. First, there is Catholic social teaching, which creates a foundation from which to respond to the environmental violence of mining in suitably complex and integral ways. Second, the Catholic community has a vibrant base of grassroots actors defending people and the environment from mining damage. And third, there is the church’s institutional capacity to network those grassroots actors and coordinate their work with national and international efforts to change resource governance and industry practice. The argument is not that these resources are necessarily unique to the Catholic community. The idea is that the Catholic community can array and marshal these resources in a distinctive way that gives it special potential for responding to mining and environmental violence.
