A statement released by the Holy See Press Office highlights His Holiness’s words, addressed to the participants in a meeting of the Particular Churches of the Global South at the Amazon Museum in Belem, in which he warned that “the political will of some is failing” to comply with the climate pact.

Leo XIV stressed the importance of the Paris Agreement, a legally binding international treaty on climate change adopted in 2015, aimed at limiting global warming to less than 2.0 degrees Celsius through a reduction in greenhouse gas emissions.

He noted that the treaty “has spurred real progress and remains our most powerful tool for protecting people and the planet,” but “our response” is failing, and asserted, “true leadership involves service and support on a scale that can truly make a difference.”

The Bishop of Rome affirmed, “stronger climate action will create more robust and fairer economic systems,” while “firm political and climate measures are an investment in a fairer and more stable world.”

The Pope delivered on November 7 a message to COP30, which was read to the attendees by Cardinal Pietro Parolin, Secretary of State of the Vatican City, in which he urged that the forum become a sign of hope.
