Pope Leo signals strong support for climate action and environmental care
The first U.S.-born pope, Leo XIV, has indicated he will continue the Catholic Church’s growing focus on environmental stewardship and climate responsibility, building on the legacy of Pope Francis.
Aynsley O’Neill reports for Living on Earth.
In short:
- Pope Leo XIV, formerly Robert Prevost, has a history of environmental engagement, including partnerships with Indigenous and interfaith rainforest initiatives during his tenure in Latin America.
- In past public remarks, he criticized exploitative interpretations of biblical dominion over nature, emphasized the need for reciprocity with the environment, and called for ethical scrutiny of new technologies.
- His chosen papal name references Pope Leo XIII, whose 1891 encyclical launched modern Catholic social teaching, suggesting a similar commitment to confronting today’s economic and ecological crises.
Key quote:
"The great command that Jesus taught is to love your neighbor as yourself. We can't do that anymore without caring for creation, because the damage done to creation is undermining the well being of the neighbor."
— Erin Lothes, environmental theologian with the Laudato Si’ Movement
Why this matters:
As climate disasters grow more frequent and severe, many faith leaders are amplifying calls to care for the Earth not just as a moral duty, but as a spiritual imperative. Pope Leo XIV, as an American with direct experience in Latin American environmental issues, is uniquely positioned to bridge cultural divides on climate discourse. His background also allows him to speak persuasively to industrialized nations most responsible for greenhouse gas emissions. Faith-based advocacy has already pushed companies, governments, and communities toward renewable energy and conservation. By embracing ecological values as central to Catholic teaching, the new pope could invigorate grassroots and institutional efforts alike.
