A new initiative invites Catholic organizations to review where their resources are invested and to divest from companies linked to harmful mining practices.

The Catholic bishops' conferences of Africa, Asia and Latin America called for the world's governments to "adopt a treaty to stop proliferation and abandon fossil fuels as a moral and political imperative."
