Speaking to a gathering of prosecutors and criminologists, Pope Francis called for more accountability for international corporations that damage nations, people, and the environment.

“One frequent omission of penal law is the insufficient attention the crimes of the powerful receive, especially the large-scale delinquency of corporations,” Francis told participants of the 20th World Congress of the International Association of Penal Law, a network of experts in penal law and criminology with more than 3,000 members.

In his speech, the pope condemned global corporations that are responsible for “countries’ over-indebtedness and the plunder of our planet’s natural resources.” He said that their activities have the “gravity of crimes against humanity,” especially when they lead to hunger, poverty and the eradication of indigenous peoples.

“We must introduce, (the synod’s bishops) were thinking, in the catechism of the Catholic Church, the sin against ecology, against our common home, because it is our duty,” Francis said.
