This presentation summarizes ICLEI's work on climate action and sustainable mobility. ICLEI is a network of over 1,500 local governments that aims to build capacity for climate action. It outlines ICLEI's Local Government Climate Roadmap process and the Nantes Declaration adopted by mayors committing to climate goals. The presentation also describes ICLEI's GreenClimateCities program methodology and online training platform to help local governments inventory emissions, create climate plans, and implement projects across sectors like mobility, buildings, waste and water. Current mobility projects supported by ICLEI are also listed.
