We are proposing a global declaration, campaign and action agenda called ‘Faiths for Forests’ which would be endorsed at the Religions for Peace World Assembly (August 2019) by over 1,000 of the world’s most senior and influential religious leaders, officially launched as a contribution to the UN Climate Action Summit, and culminate at a high-level ‘Faiths for Forests’ summit in conjunction with the UN Conference of the Parties to the Convention on Biological Diversity (COP15) in China.
