Today, 55% of the global population lives in cities. This is set to go up to 68% by 2050, adding another 2.5 billion people to urban areas by 2050.
Cities contribute 60% of global GDP but rapid and unplanned urbanization worsens the triple planetary crisis. Yet, cities are key players in addressing environmental challenges; 70% of climate solutions are within subnational jurisdictions. UNEP supports cities worldwide in mitigating their environmental impacts and increasing resilience of urban systems, focusing on buildings, transport, food, energy, cooling, biodiversity, and more.
