I'm interested in the Reinventing Cities competition. Can you tell me about three different cities participating and one specific site for each? Also, what is the main goal of this competition as described in the application guidelines?
Navigate to the 'Sites in competition' page. Identify three distinct participating cities and one specific site for each by clicking on city links and scrolling if necessary. Navigate to the 'Application Guidelines' page. Locate the 'Objectives' section and extract the primary objective of the competition. Provide the list of cities and their sites, and the main objective.
List three distinct cities participating in the 4th edition (e.g., Milan, San Antonio, Montréal) and for each, state one specific site (e.g., for Milan: Via Zama, for San Antonio: Material Innovation Center, for Montréal: 150 Louvain Ouest). State the primary objective of the Reinventing Cities competition exactly as it appears in the 'Application Guidelines': 'Reinventing Cities is an international competition initiated by the C40 to stimulate ambitious carbon-neutral developments across the globe and to transform underutilized sites into beacons of sustainability and resilience.'
