The final declaration of Rio underlines in its article 267 the role played by innovative financing.

This declaration confirms the support of the United Nations to the efforts realized by the Leading Group in favour of the scaling-up of innovative financing in order to reinforce the struggle against poverty.

Here is the paragraph 267:

"267. We consider that innovative financing mechanisms can make a positive contribution in assisting developing countries to mobilize additional resources for financing for development on a voluntary basis. Such financing should supplement and not be a substitute for traditional sources of financing. While recognizing the considerable progress in innovative sources of financing for development, we call for a scaling-up of present initiatives, where appropriate."
