The Fast for the Climate campaign is an interfaith initiative bringing people of different faiths to fast, as a spiritual exercise, in solidarity with the victims of climate change. People are invited to fast the 1st of each month. The WCC is one of the co-sponsors of this initiative.
In a comment, the WCC general secretary Rev. Dr Olav Fykse Tveit said, “the WCC 10th Assembly has recently stressed the urgency of climate crisis in a Minute on Climate Justice. The interfaith fast for climate justice is one concrete way churches and other religious institutions have expressed their concern about the situation and the negotiations at COP 19 in Warsaw.”
The fasting can be seen as a component of the pilgrimage of justice and peace, called by the WCC Assembly message. On climate, the pilgrimage has a relevant milestone at the Interfaith Summit on Climate Change in September. Other relevant milestones in this climate pilgrimage are the 20th session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP20) in Lima in December 2014 and COP21 in Paris, December 2015.
