FEATURED LEADER

Dr. Maimunah Mohd Sharif, Mayor of Kuala Lumpur, Malaysia

Under the leadership of Datuk Seri TPr Dr. Maimunah Mohd Sharif  -Mayor of Kuala Lumpur, former Executive Director of UN-Habitat, and advisor to the ICLEI Global Executive Committee-, the city is advancing a comprehensive sustainability agenda. Kuala Lumpur is accelerating action across energy, urban greenery, waste management, housing, transportation, and education, strengthening its commitment to a healthier, more sustainable urban future.

As both a local leader and Malaysia’s Special Envoy for Sustainable Urbanization, Mayor Sharif is bringing global climate discussions directly to communities. She convened the Kuala Lumpur Town Hall COP, the first city in the ASEAN region to host such an event, calling on all ASEAN cities to organize their own Town Hall COPs. She also urged the COP30 Presidency to elevate the Urban Agenda across all COP meetings, a priority later captured in the Kuala Lumpur Call to Action for COP30.
