When Pope Francis stepped onto the balcony of St. Peter’s Basilica in 2013, few could have predicted that this Argentinian Jesuit would become one of the world’s most influential voices on climate change.
But over the past decade, Francis had done exactly that—positioning the Catholic Church not only as a spiritual authority but as a force for environmental justice.
In 2015, the pope released a groundbreaking encyclical called Laudato Si’, or “Praise Be to You". It was more than a religious document—it was a bold and beautifully written plea to humanity to care for “our common home”.
Francis didn’t mince words: environmental destruction is a moral crisis, and the poor—who contribute least to climate change—are suffering the most because of it.

Francis’s message struck a chord beyond Catholic circles. His voice carried into United Nations halls and global climate conferences. Some analysts believe his leadership helped sway public and political opinion in favour of the 2015 Paris Climate Agreement.
He even invited oil executives to the Vatican, urging them to transition toward sustainable energy. In 2023, he addressed the COP28 climate summit and reminded world leaders that the clock is ticking:
“The future of us all depends on the present that we now choose.”

Eight years after Laudato Si’, Pope Francis doubled down with another powerful statement: Laudate Deum, released in 2023. This time, he focused even more directly on human-caused climate change and the systemic barriers that prevent real action.
He called out the failures of international summits and demanded real accountability—not just more words:
“We are in the same boat… but some of us are steering it, and others are bailing water.”

What makes Pope Francis’s approach unique is how he connects the dots between faith, science, social justice, and environmental responsibility. He’s not just saying “plant trees”—he’s saying our spiritual health is tied to the health of the Earth and its people.
As climate threats grow more urgent, Pope Francis has become a rare voice of moral clarity. And even as questions about his eventual successor loom, his message is clear: caring for the planet isn’t optional—it’s sacred.
