We boost the impact of our organization and strengthen the capacity of our members. Together, we touch the everyday lives of millions of people through economic development projects; academic and scholarship opportunities; resilient cities initiatives and environmental programs; arts and cultural activities; and municipal, youth, and sports exchanges.
