FEATURED MEMBER
Ulaanbaatar, Mongolia
An ICLEI Member since 2014, Ulaanbaatar was the first local government in Mongolia to join the global network. Over the past decade, ICLEI and the city have collaborated on priorities including air quality, sustainable mobility, district energy, building efficiency and urban resilience, demonstrating the value of international cooperation in advancing locally led sustainability solutions.
Under the leadership of B. Purevdagva, Governor of the Capital City and Mayor of Ulaanbaatar, the city hosted the UNCCD COP17 Mayors’ Forum, co-organized by the UNCCD Secretariat, UN-Habitat and ICLEI. The Forum culminated in the Ulaanbaatar Declaration, calling for a stronger role for local and regional governments in the UNCCD process, and the Ulaanbaatar Initiative to test practical approaches for cities to measure and report land degradation.
