U.S. bishops and other Catholic leaders are offering “prayers of support and solidarity” for world leaders who will discuss climate change and other environmental matters at an upcoming conference.

The 30th annual United Nations Climate Change Conference (COP30) is scheduled for Nov. 10–21 in Belém, Brazil. World leaders, scientists, and representatives from civil society will discuss ways to implement solutions to combat climate change and form new national action plans. 

Archbishop Borys Gudziak, chair of the United States Conference of Catholic Bishops’ (USCCB) Committee on Domestic Justice and Human Development; Bishop A. Elias Zaidan, chair of the Committee on International Justice and Peace; and Sean Callahan, CEO of Catholic Relief Services (CRS), are calling for “urgent, courageous action to protect God’s creation and people.” 

“This year’s COP30 convenes while the Catholic Church celebrates the Jubilee Year of Hope,” the leaders said in a Nov. 4 statement. It is “a sacred opportunity to restore relationships and renew creation at a time when the gift of life is under grave threat.”

“Pope Leo XIV called for the participants of COP30 to ‘listen to the cry of the Earth and the cry of the poor, families, Indigenous peoples, involuntary migrants and believers throughout the world,’” the leaders said.

“Climate change, biodiversity loss, and environmental degradation are devastating communities already burdened by poverty and exclusion. Farming and fishing families confront threats to their livelihoods; Indigenous peoples face destruction of their ancestral lands; children’s health, safety, and futures are at risk,” the statement said.

“A decade ago, in Laudato Si’, Pope Francis reminded us that the climate is a common good, belonging to all and meant for all, and that intergenerational solidarity is not optional,” the statement said. “Failing to steward God’s creation ignores our responsibility as one human family.”

The leaders are calling on world leaders to act “urgently” to implement the Paris Agreement, a 2015 international treaty to limit global warming that “protects God’s creation and people.”

The leaders asked that countries and civil society organizations recommit to implementation that fosters economic opportunities, commits to efforts that reduce climate warming emissions, and pledges loss and damage financing that guarantees priority and direct access to vulnerable communities. 

They also asked that they ensure a just transition to a sustainable economy centered on workers, communities, and creation and make financing for climate solutions timely and transparent while also upholding human dignity.

“As all of us are impacted, so must we all be responsible for addressing this global challenge,” the leaders said. “Together, these actions can work towards integral ecology and ‘give priority to the poor and marginalized in the process.’”
