This document discusses ICLEI's PACMUN initiative in Mexico to support local climate action planning among Mexican municipalities. The initiative started with 9 pilot municipalities in 2012 and grew to 76 municipalities by the end of 2012, with a goal of including 200 municipalities representing 64% of Mexico's population by 2013. The PACMUN municipalities report undertaking mitigation actions like improving transportation, waste management and land use, as well as adaptation actions like education programs, water resource management and urban infrastructure improvements. The document outlines next steps like expanding PACMUN's implementation, replicating it regionally, developing case studies, and highlighting PACMUN's role in Mexico's national climate actions and commitments under the UNFCCC.
