Speaking to a group of lawyers on Friday, Pope Francis said that the Catholic Church is contemplating the introduction of “ecological sin” to the compendium of Church teaching.

“We have to introduce, we are thinking about it, in the catechism of the Catholic Church, the sin against ecology, the sin against our common home, because it’s a duty,” he said.

The pope’s words came just weeks after the conclusion of a bishops’ summit on the Amazon focused on the environmental threat to the region.

Francis was speaking to the 20th world congress of the International Association of Penal Law, held in Rome Nov. 13-16, under the scope of “Criminal Justice and Corporate Business.”

Harking back to the recently concluded Synod of Bishops on the Amazon, during which the bishops condemned the “sins against the environment,” Francis on Friday denounced the “ecocide” that corporations are “usually responsible for,” urging lawyers to guarantee these crimes don’t go unpunished.

By ecocide, he said he meant the “massive contamination of the air, of the land and water resources, large-scale destruction of flora and fauna, and any action capable of producing an ecological disaster or destroying an ecosystem.”

The loss or the destruction of ecosystems of a specific territory, Francis said, is a fifth category of crimes against peace, which should be recognized as such by the international community.
