On June 16, 2026, Pope Leo XIV sent a message to participants of the Austrian World Summit organized by Arnold Schwarzenegger, reports Life Site News. In his address, the pontiff called on people of various faiths around the world to strengthen "care for creation" and work toward building a society based on "solidarity and human dignity".

Referencing the encyclical Laudato Si', Leo XIV emphasized that protecting the environment is not an "optional" but a mandatory aspect of Christian experience. According to the head of Catholics, those who believe in God's creation of the world are obliged to take even greater responsibility for nature, as "religious faith reinforces the overall desire to protect life and care for nature".

"While to some, faith may seem to have little to contribute to questions of climate change and environmental protection, the religious dimension is in fact essential to address these issues adequately," he stated.

The pontiff also called for international cooperation, together with "cohesive and forward-looking multilateralism," in order to overcome various fears: fear of changing course, fear of losing power and fear of uncertain outcomes, and therefore find effective solutions.

Special attention in the address was paid to economic aspects. In the context of preparations for the UN climate conference COP30, Leo XIV expressed hope for a transition to models in which "the common good takes precedence over profit." He explicitly stated the need for "wealthier countries to meet their obligations to support poorer countries financially."

As the UOJ reported, the pope called on Europeans to respect the dignity of migrants.
