Laudato Si’ Week is a celebration held annually in May to mark the anniversary of Pope Francis’s landmark encyclical on caring for creation. Sponsored by the Vatican’s Dicastery for Promoting Integral Human Development, this global celebration unites Catholics to listen and respond together to the cry of creation, rejoice in the progress we have made in bringing Laudato Si’ to life, and intensify our efforts through the Laudato Si’ Action Platform as well as other opportunities for education and action.
