Cities, widely acknowledged as catalysts for development in the physical, social, and economic domains, are seen as crucial for the future of both communities and humanity for the following reasons: holding a high proportion of national population by cities; generating large employment; making major contribution to the economy; with quality infrastructure besides supporting, and innovating state-of-the-art technologies for development. Housing more than 50% of the global population generate global GDP of 80%, consuming global energy of more than two-third and emitting more than 70% of annual global carbon, cities are known for their dualities. Cities have to be at the forefront to address the climate change and global warming. Globally recognized as large amounts of energy consumers, natural resources and large amounts of waste generators, cities have emerged as the major cause of numerous adversities that are being faced by humanity and planet Earth and is an ideal breeding ground for disasters. Taking a comprehensive approach, planning, management, and governance practices in cities have a significant impact on issues pertaining to bio-diversity, the environment, global warming and increasing carbon footprints, and climate change. People are being made to travel; buildings are being designed, constructed, and operated; the urban heat islands effects; however, the green spaces are eluding the majority of residents. The cities have to get grips with these natural and manmade disasters and make planet earth more qualitative, livable, and sustainable. The cities need to be planned, designed, developed, and managed rationally and innovatively to counter the challenges posed by climate change and global warming. In the pursuit of searching suitable solutions, this paper will look at the options of promoting planned development, making cities compact; promoting a circular economy to make cities more sustainable and carbon neutral.
