Cities occupy about 3% of Earth’s surface and are responsible for over 70% of global greenhouse gasses emission and use 3/4 of global energy. They say that by 2050 almost 85% of the European population is going to live in the cities. That is why to implement the prevention of climate change, the participation of the cities is mandatory. We can not avoid climate change disasters anymore but can slow down the process to minimize its consequences. Furthermore the recent events in the last three years brought into light other challenges that cities must face. Covid-19 pandemic has impacted our lives and the city’s priority development plans significantly.
