Pope Leo XIV has issued a call for urgent, coordinated action to combat climate change as world leaders gather for critical negotiations.

The pontiff’s comments, delivered via video at the United Nations climate summit in Brazil, stress the need for “concrete actions” over empty promises and aspirations.¹

Warning that the Earth “is crying out in floods, droughts, storms and relentless heat”, Leo XIV places moral responsibility squarely on governments and individuals alike.²

He criticises the lack of political will that has hampered progress since the landmark Paris Agreement was signed a decade ago.

Pope Leo condemns climate change denial as well as attempts to shift the blame for environmental harms onto the world’s most vulnerable people.³

Building on the legacy of Pope Francis, Leo XIV identifies care for the environment as a central tenet of Catholic social teaching.

The reaction from faith leaders, environmentalists, and politicians has been largely supportive, echoing his call for solidarity and urgent action.⁶

His intervention raises the stakes ahead of key decisions at the climate talks, putting moral and political leaders under new pressure to act decisively.

Pope Leo’s Stand on the Climate Crisis

Pope Leo XIV’s recent interventions on climate change mark a defining stance for his papacy and the Catholic Church’s global agenda.

In his latest address, he tells nations that their progress to date is “not enough”, insisting that God’s creation demands urgent protection.¹

He links environmental damage directly to human decision-making and insists that “only then will it be possible to mitigate the damage done to the environment.”

Leo XIV, as the first American pope, has shown a willingness to connect the moral teachings of the Church to global policy debates.

At the United Nations climate summit in Belém, Brazil, he argued that the Paris Agreement remains the world’s “strongest tool for protecting people and the planet” but that it is the failure of political will, not flawed agreements, that is holding back real change.²

This call for new political momentum comes exactly ten years after the adoption of the Paris climate agreement, when governments pledged to limit warming to well below 2°C.

Current emissions trends now put the world on track to overshoot this goal, raising fears of devastating climate impacts.

Condemnation of Denial and Indifference

Pope Leo has sharply criticised climate change denial and the mockery of those fighting global warming, renewing the Vatican’s firm opposition to misinformation.³

At Castel Gandolfo, marking a decade since “Laudato Si’”, he spotlighted those who “choose to deride the increasingly evident signs of climate change, to ridicule those who speak of global warming, and even to blame the poor for the very thing that affects them most.”

He speaks “inspired by unity and togetherness”, asserting that there is “no room for indifference or resignation” regarding the climate emergency.⁴

The Pope’s words are widely read as a challenge to powerful leaders who either deny climate science or undermine global cooperation.

The Moral and Social Context

Pope Leo invokes a deep sense of moral responsibility to care for creation, drawing on Catholic theology and social doctrine.

He stresses that “God will ask us if we have cultivated and cared for the world that he created for all and for future generations.”⁵

Climate change, he warns, disproportionately affects the poorest and most vulnerable, further entrenching inequalities.

The pontiff underscores that faith communities can play a pivotal role by mobilising citizens to demand action from their leaders.

He backs practical measures, like the Vatican’s commitment to solar power and sustainable transport, providing a model for governments and institutions worldwide.

Response and Repercussions

Leo XIV’s intervention comes at a critical time, as negotiators at COP30 in Brazil strive for tougher climate action and increased funding for developing nations.⁶

The Pope’s address has drawn praise from other religious and political figures, including environmental campaigners who see his leadership as a force for unity and hope.

Catholic leaders such as Bishop John Arnold echo the pontiff’s emphasis on international cooperation, while former California governor Arnold Schwarzenegger has lauded Leo XIV’s work as “action hero” leadership.⁴

Officials at the United Nations climate summit have welcomed the Pope’s call for bolder commitments and greater attention to those most at risk from global warming.²

As the climate summit continues, Pope Leo’s message is likely to resonate far beyond the Catholic Church, challenging both policymakers and ordinary citizens to rethink their roles in the fight against climate change.

With the world’s eyes on Brazil, the forceful intervention by the new Pope raises expectations for a major step forward—if leaders are willing to follow through.¹
