COP30 — a moral reckoning

When the Vatican’s Secretary of State Cardinal Pietro Parolin addressed the 30th edition of the Conference of the Parties (COP30) in Belém, Brazil on behalf of Pope Leo XIV, his words carried the weight of both prophecy and pastoral concern: “If you want to cultivate peace, care for creation.”

In that single line, the Holy Father drew a direct link between peace on Earth and the care of our common home—a truth the Church has long proclaimed, but which the world still resists living.

The timing could not be more urgent. The year 2025 has seen creation itself groaning under the strain of human neglect and climatic disasters. Super Typhoon Kalmaegi killed more than 200 in the Philippines, and in our region Hurricane Melissa last month left a deadly trail of devastation in Jamaica, Cuba and Haiti. Wind-whipped wildfires in South America and southern Europe have left scorched lands. These all testify to what Pope Francis described in Laudato Si’ as “the cry of the Earth and the cry of the poor.”

These are not distant headlines; they are warnings written in wind, fire, and flood. The most vulnerable—those least responsible for this crisis—continue to pay the highest price.

Over the past 30 years, from the first COP in Berlin, Germany in 1995 to the landmark Paris Agreement of 2015, the world has sought to act together for the planet’s future. Yet despite declarations and commitments, a chasm remains between promises not kept and real concerted action.

COP30, which runs from November 10 to 21, is not simply another global meeting of the United Nations Framework Convention on Climate Change—it is a moral reckoning.

Pope Leo XIV’s message lamented a growing “collective selfishness, disregard for others and short-sightedness”. He urged leaders to rediscover what true cooperation means: not political expediency, but shared responsibility rooted in respect for the Creator’s design.

The Pope’s words renew the call of Laudato Si’ for an ecological conversion—a transformation that begins in the human heart. This conversion challenges the illusion that humanity stands apart from or above creation. It invites us to rediscover our role as caretakers, not exploiters, of the Earth.

Environmental destruction and human conflict are not separate tragedies; they are two faces of the same moral failure. To harm creation is to wound peace itself.

Pope Leo XIV also emphasised the urgent need for a just global economy. He called for a “new human-centred international financial architecture” that addresses both ecological debt and foreign debt.

Wealthy, heavily industrialised nations must recognise their moral obligation toward those already suffering from the climate crisis. Without justice for these communities, any talk of sustainability is hollow. Real peace, the Pope reminds us, cannot exist without fairness and compassion.

For the Church, this moment is both challenge and mission. Every Catholic community is called to witness to integral ecology—not only through environmental initiatives, but through formation, advocacy, and prayer.

To teach respect for creation is to teach reverence for life itself. The task before us is not political activism disguised as faith; it is faith lived authentically in a wounded world.

Thirty years of climate deliberations and negotiations have shown that science and policy, though essential, are not enough. What is lacking is the moral courage to change.

The storms of 2025 have spoken their warning. The voice of the Church, through Pope Leo XIV, offers another—a call to repentance, renewal, and in this Jubilee Year, hope.

If COP30 is to mean anything, it must mark not just another chapter in human debate, but the beginning of human conversion.
