Pope Francis is set to take a number of measures to tackle climate change in 2015 - including issuing a document to Catholics around the world.
His edict will be sent to 5,000 bishops and 400,000 priests who will then distribute it to parishioners - it will urge all Catholics to take action on moral and scientific grounds, according to the Guardian.
The pontiff will also give an address to the UN as well as call for a summit of leaders from all the world's major religions.
Our academics supported the pope’s initiative to influence next year’s crucial decisions. The idea is to convene a meeting with leaders of the main religions to make all people aware of the state of our climate and the tragedy of social exclusion.

According to Vatican insiders the Pope will try to lobby politicians in the build-up to the crucial climate summit in Paris in November.
