This project aims to deliver important information, methodologies and guidelines for use by city planners and other prominent decision makers throughout Latin America and the Caribbean and Asia, applying eco-effi cient criteria to reduce emissions, save energy and natural resources, and enhance social inclusion. ECLAC views this project as an important milestone in the ongoing efforts surrounding eco-effi ciency and sustainable urbanization. We look forward to continuing the global dialogue on urban and regional eco-effi ciency and to exchanging experiences in order to learn from each other’s know-how and expertise
