Which organization collaborated on developing the Melbourne Principles?

The Melbourne Principles were developed through collaboration between the United Nations Environment Programme (UNEP) and the International Council for Local Environmental Initiatives (ICLEI). These principles focus on sustainable urban development and aim to provide guidelines for local governments to promote sustainability initiatives. UNEP's involvement signifies a commitment to international environmental standards, while ICLEI represents local governments committed to sustainability. This partnership underscores the importance of both global and local efforts in addressing environmental issues, as local governments play a critical role in implementing sustainability practices.

The other organizations mentioned do not have a direct relation to the formulation of the Melbourne Principles. While entities like NASA, the World Bank, the International Monetary Fund (IMF), the World Health Organization (WHO), and the Food and Agriculture Organization (FAO) play significant roles in their respective fields, they were not part of this specific initiative aimed at urban environmental strategies.
