The Vatican Dicastery for Promoting Integral Human Development, on behalf of the Vatican, is planning a 40-day prayer and promotion campaign in October to help people around the world discern and implement their response to Laudato Si’. Institutions, communities, families and individuals are invited to commit to the planning process through the Laudato Si' Action Platform. The enrollment period is scheduled to open on Sunday, Nov. 14. At that time, planning guides and related materials for the program — a type of sustainability road map guided by church teaching — will be available on the initiative's website, mentioned above.
