From October 1–3, 2025, Castel Gandolfo (Italy) will host the international conference “Raising Hope for Climate Justice”, a historic gathering to mark the tenth anniversary of the Laudato Si’ encyclical and to foster a global response to the climate and ecological crisis from the perspectives of faith, politics, and civil society.
The event will feature His Holiness Pope Leo XIV, alongside prominent leaders such as Brazil’s Environment Minister Marina Silva and former California Governor Arnold Schwarzenegger, along with bishops, international agency officials, indigenous leaders, climate and biodiversity experts, and civil society representatives.
Over three days, the conference will include keynotes, panel discussions, spiritual moments, and cultural events that highlight both the progress made since Laudato Si’ and the urgent steps needed ahead of COP30 in Brazil.
The event will be held in person at Castel Gandolfo and streamed live, enabling thousands of people and media outlets worldwide to follow the main messages and join the global conversation.
You can register for the livestreaming or access the recording here.
This event is organised by Laudato Si’ Movement in partnership with CIDSE, CAFOD, Fastenaktion, Trócaire, SCIAF, as well as the Dicastery Promoting Integral Human Development, Dicastery for Communications, Catholic Climate Convenant, Centro di Alta Formazione Laudato Si’, Caritas Internationalis, Focolare Movement, Ecclesial Network Alliance (ENA), and International Union Superiors General.
