Dr. Mostafa Tolba Architect of the Montreal Protocol, IPCC and Biodiversity Convention

This statement by the International Institute for Sustainable Development (IISD) commemorates the life and legacy of Dr. Mostafa Tolba, who led the United Nations Environment Programme (UNEP) for nearly 20 years and played a pivotal role in establishing the foundations of international environmental law.

• Dr. Mostafa Tolba is credited as the architect of the global environmental agenda, having led the United Nations Environment Programme (UNEP) for nearly 20 years. His leadership focused on a framework based on science, treaty consensus, and financial support, specifically promoting the concept of "development without destruction."
• The Montreal Protocol is described as Tolba's most significant legacy and the world's most successful environmental treaty. It was the first treaty to achieve universal membership and served as a "start and strengthen treaty" that evolved through amendments. It established a model for later agreements, including the Paris Agreement, by introducing a stand-alone fund for developing countries and a scientific review process.
• Beyond the Montreal Protocol, Dr. Tolba was instrumental in the creation of several other major international environmental frameworks and institutions. He co-founded the Intergovernmental Panel on Climate Change (IPCC) and the Global Environment Facility, and he steered the negotiations for the Basel Convention on transboundary hazardous waste and the Convention on Biodiversity.
• Tolba's approach to environmental governance was characterized by the integration of scientific evidence with political diplomacy. He advocated for precautionary action in the face of uncertainty and ensured that the perspectives of developing countries remained central to collective global action.
