Over the course of the PACMUN project, ICLEI has worked with over 450 Mexican municipalities to develop GHG inventories, collect data and define local climate action plans. Project activities focus on building the capacity of municipal staff to establish goals and prioritize actions on climate and resilience. Municipalities also work with ICLEI to report their climate and data and can voluntarily submit their climate action plans to the Ministry of Environment.

Through collaboration on the OPCC, which is led by WWF, ICLEI aims to encourage the reporting of climate related data from local governments around the globe, and to improve the quality of the reported data.

In partnership with CDP, ICLEI provides CDP and ICLEI’s unified reporting system for the report of the data of OPCC participating cities.

ICLEI supports cities by checking their submitted data and by providing guidance. The OPCC acts as vehicle to raise ambition towards climate action globally, as well as to showcase the commitment from local and regional governments.

ICLEI can help raise ambition and connect cities, towns, and regions who are seeking to solve the problems of climate change. The GreenClimateCities (GCC) Program offers cities a proven process methodology for walking step-by-step toward climate neutrality.The GCC program supports local communities on the front lines addressing the challenges and opportunities of urban growth, exploring the potential of green economy and green/blue infrastructure and pursuing a low emission and climate resilient development trajectory. The GCC methodology is a nine step process offering support on assessing climate risks and vulnerabilities and integrating low-to-no emissions development and climate adaptive development) into urban development policies, plans, and processes. It consists of a wide range of resources, tools and guidance notes to support local and regional governments to deliver ambitious local climate action.
