This book, produced under the auspices of the OECD Working Party on Biodiversity, Water and Ecosystems, considers the opportunities for scaling-up finance for biodiversity from six “innovative financial mechanisms” (as classified in Goal 4 of the Convention on Biological Diversity’s Strategy for Resource Mobilization). These are: environmental fiscal reform; payments for ecosystem services; biodiversity offsets; markets for green products; biodiversity in climate change funding; and biodiversity in international development finance.
