For several decades local governments have had institutions, human, financial, technical and management resources for the different tasks related to mitigation and adaptation to climate change; Are the cases of the governments of the Federal District, London and New York. These governments represent experiences that enable lessons to be learned from both successes and failures, particularly with regard to institutional capacities. This book explores what institutional capacity a local government needs to address climate change. To answer this question, the present study attempts to specify the institutional capacity required by local governments to deal with climate change. To achieve this, a reference model of this capacity is designed to serve as a basis for the analysis and diagnosis of the capacity developed by the Federal District Government to address the problem of climate change.
