What they do
ICLEI is a global network of 2,500+ local and regional governments committed to sustainable development. They provide tools, training, and peer learning networks for cities working on climate mitigation, adaptation, biodiversity, circular economy, and equitable development. Their GreenClimateCities program provides a structured methodology for developing and implementing urban climate action plans.
Why they matter
While C40 focuses on megacities, ICLEI includes mid-size and smaller cities that collectively represent a larger share of global population. Their tools and methodologies are designed to be implementable by cities with limited budgets and staff. The GreenClimateCities methodology has been adopted by hundreds of cities, providing a standardized approach to urban climate planning that enables comparison, collaboration, and accountability across diverse contexts.
How to support
Encourage your local government to join ICLEI and use their planning frameworks. Access free planning tools and case studies. Attend ICLEI events and webinars on urban sustainability best practices.
