Organized by SmartCitiesWorld, the Cities Climate Action Summit 2025 is a key global forum for city leaders, local governments, and sub-national actors committed to tackling the climate crisis head-on. This year’s summit will continue to build momentum around practical, inclusive, and scalable urban climate solutions.

Following the success of the 2024 edition, which brought together thought leaders from cities worldwide, the 2025 summit will feature high-level dialogues, interactive workshops, and collaborative sessions. The program is designed to address urgent climate challenges facing urban areas—while promoting equity, innovation, and resilience.

Attendees will dive into critical themes including policy design, technological innovation, and community-centered approaches. The goal: to equip city practitioners with the tools, insights, and networks needed to turn bold climate commitments into transformative local action.
