By 2040, cities can become much greener and more adapted to the needs of the population. One of the main problems that should be addressed is air pollution. More green areas could be introduced in the cities of the future to help reduce pollution and improve air quality. In addition, cities could use advanced technologies, such as intelligent transport systems, to optimise traffic and reduce emissions.

Another important aspect is energy consumption. Future cities could be supplied with renewable energy sources such as solar and wind energy. Buildings could be designed to be energy-efficient and efficient. More public transport options that are environmentally friendly and user-friendly could also be introduced.

Finally, cities could become more community-based and socially responsible. More public spaces could be created where people can communicate and spend time together. It could also promote the local economy and support small businesses.
