The urban population worldwide is increasing rapidly which is 55% of the world’s population at a rate of 1.9%. There is going to be a double in the urban area population over the next 40 years. In 2025, it is imagined that 70% of the world's population is going to live in cities. With an increase in population there comes negative effects such as automobiles increase and adverse effects such as health, social and environmental impacts. Green mobility is envisioned to be the future of cities. There has been a positive connection between environmental benefits and green mobility in Saudi Arabia mostly in a future city such as Riyadh. Diversified energy is needed urgently, especially the transition towards renewable energy. More studies are needed on a national level and different stakeholders need to come together to discuss their actions on green mobility in order to improve the quality of life and the environment.
