The Vatican urged Catholics to disinvest from fossil fuel industries and to closely monitor companies in sectors such as mining to check if they are damaging the environment.
The calls were contained in a 225-page manual for church leaders and workers.
It marks the fifth anniversary of Pope Francis’ landmark encyclical “Laudato Si” (Praised Be) on the need to protect nature, life, and defenseless people.
The compendium suggests practical steps to achieve the goals of the encyclical, which strongly supported agreements to contain global warming and warned against the dangers of climate change.
The Vatican bank has said it does not invest in fossil fuels and many Catholic dioceses and educational institutions around the world have taken similar positions.
