Sustainable Cities: An Overview

The purpose of this paper is to analyze and highlight the essential role and importance of sustainable development in harmony with the environment, in accordance with all approvals in place without endangering the integrity of the environment, natural protected areas, natural habitats, wild flora and fauna. It is increasingly evident that various challenges facing urban areas - economic, climatic, social, demographic and environmental - are closely interlinked and success in urban development can only be achieved through an integrated approach. Most cities produce countless current energy waste and inefficiency. For cities to find a place in the future of the Green Planet, they must transform into pure entities. Among the many actions that a city can take are: urban planning to ensure a moderate density and air quality, efficient public transport system that can replace the individual car, promotion of culture and traditions, integrating disadvantaged people and stimulate people that have potential, encouraging sustainable businesses and restricting large polluters, etc. In 1994, many European cities have signed the Aalborg Charter of European Cities & Towns Towards Sustainability, which respects the principles of Agenda 21 and have the objective of creating the framework for sustainable development of urban areas.
