Pope Francis: More Sustainable Cities Can Help with Population Decline

He praised those present for their reconstruction efforts, especially the attention to climate change, sustainability, and respect for nature.

Pope Francis will speak on the climate and related issues at the COP28 climate change conference in Dubai, United Arab Emirates, where he will travel Dec. 1–3. It will be Francis’ first time attending and addressing part of the 13-day conference.

Climate issues and the environment have been a priority of Pope Francis’ pontificate.

In October, he released his second major document on the topic, the apostolic exhortation Laudate Deum (“Praise God”), in which he warned of “grave consequences” if humanity continues to ignore the threat of climate change.

In his speech on Friday, Francis quoted from Laudate Deum, saying “there is no doubt that the impact of climate change will increasingly harm the lives of many people and families. We will feel the effects in terms of health, jobs, access to resources, housing, forced migration, and in other areas.”

This is why, he added, it is important to implement the necessary measures to slow or stop climate change and to provide methods for coping with the changes that have already taken place.

“Here, too, it is a matter of an open gaze, attentive to others and those who will come after us; we should not be discouraged by criticism or discontented people,” he said.
