The 2024 theme: “Youth Climate Changemakers: Catalyzing Local Action for Urban Sustainability,” for World’s Cities Day, highlights the critical role of young people in leading climate initiatives for sustainable urban development. As cities grow rapidly—with 70% of the global population expected to live in urban areas by 2050—environmental resilience, resource efficiency, and social inclusivity are more essential than ever. Sustainable Development Goal 11 underscores the importance of creating “inclusive, safe, resilient, and sustainable” cities, especially in the face of climate change.
The Urgent Need for Sustainable Cities
Urban areas consume over 75% of natural resources and produce more than 60% of greenhouse gas emissions, making cities a focal point in the battle against climate change. By 2030, up to 90% of urban growth is projected to occur in Africa and Asia, often in informal settlements where residents lack access to clean water, sanitation, and green spaces. Statistics show that approximately 1 billion people currently live in informal settlements globally, with urban poverty often exacerbated by climate challenges like extreme heat, flooding, and poor air quality.
Achieving resilient cities demands investment in sustainable infrastructure—such as green buildings, renewable energy sources, and accessible transportation—as well as inclusive governance that empowers communities, particularly youth, to lead local climate actions. This approach not only addresses environmental challenges but also fosters economic growth and social equity, enhancing the quality of urban life.
Social Impact Organizations Championing Sustainable Cities
Organizations worldwide are advancing efforts to build resilient and sustainable cities, often involving youth as central change agents:
The Trust for Public Land (USA) – This nonprofit works across the United States to create and protect green spaces that increase urban resilience, reduce heat, and improve air quality. By ensuring access to parks within a 10-minute walk for all city residents, the Trust for Public Land addresses both climate resilience and social equity.
Green Building Council South Africa – Leading the shift toward sustainable construction, the Green Building Council certifies green buildings, promoting energy-efficient design and low-carbon construction. Their Green Star SA certification has been instrumental in embedding sustainable practices within South Africa’s urban infrastructure.
Institute for Global Environmental Strategies (IGES) – Based in Japan, IGES collaborates with Asian cities to implement low-carbon and climate-resilient policies. Their partnerships with local governments on issues like waste management and renewable energy adoption have created frameworks for sustainable urban growth across the continent.
Sustainable Business Network) – This organization advocates for sustainable urban planning and has been pivotal in initiatives focused on water management, urban biodiversity, and eco-friendly infrastructure across New Zealand. Through workshops and collaborations, they support local governments and businesses in adopting sustainable practices.
Influential Leaders in Sustainable Urban Development
Several prominent leaders are pioneering innovative approaches to urban sustainability:
Elizabeth Wathuti (Kenya) – An environmentalist and climate activist, Elizabeth Wathuti has gained global recognition for her work on environmental conservation and urban sustainability. She founded the Green Generation Initiative, which plants trees and educates young people on environmental stewardship. Her advocacy has influenced urban planning policies in Kenya and beyond, highlighting the essential role of youth in creating sustainable cities.
Luca Mercalli (Italy) – An Italian climate and environmental advocate, Mercalli promotes sustainable development in European cities through research and education. His work with the Italian Meteorological Society emphasizes green architecture and urban climate resilience. Mercalli has been involved in initiatives to modernize Italy’s infrastructure, making it more resilient to climate-related impacts.
A Call to Action for Sustainable Cities
This World Cities Day, the 2024 theme emphasizes empowering young people to lead the movement for sustainable urban transformation. Establishing youth councils, integrating young representatives in local government, and fostering inclusive governance are essential for resilient and sustainable cities.
