Laudato Si’ Week

Laudato Si’ Week 2025 celebrates the 10th anniversary of the publication of Pope Francis’s encyclical Laudato Si’ in response to the ecological crisis. Since then, Catholics around the world, in parishes and small groups, have been working together to promote sustainable development.

Under the theme “Raising Hope,” this week aims, among other things, to rekindle hope “for a better future, together.” To achieve this, those in charge are inviting a wider public to take part. “Try to invite 10 people who haven’t heard of the Laudato Si’ message.”

The Green Church movement supports this approach by proposing 10 ideas for celebrating the 10th anniversary of Laudato Si’ (in French only).

At the same time, the week’s website offers a host of spiritual resources, including a prayer and novena, an event guide, a link and guide to the film The Letter, and the six-session Laudato Si’ book club.

“There is no lasting change without cultural change […] and there is no cultural change without change in people.” (LD70) This inspiring Laudate Deum quotation is a direct invitation to “personal and cultural transformation” in the face of the ecological and climate crises affecting every continent.

“I urgently appeal, then, for a new dialogue about how we are shaping the future of our planet. We need a conversation which includes everyone, since the environmental challenge we are undergoing, and its human roots, concern and affects us all.” – Pope Francis, Laudato Si’, 14
