Green cities are urban areas that prioritize sustainability and the environment. They aim to reduce carbon emissions, increase energy efficiency, promote green spaces and biodiversity, and improve the quality of life of their citizens. Green cities often rely on renewable energy sources, such as solar and wind power, to reduce their carbon footprint. They also incorporate green infrastructure, such as green roofs and walls, rain gardens, and urban forests, to mitigate the effects of climate change and promote biodiversity. By promoting sustainable transportation options, such as biking and public transit, green cities reduce traffic congestion and air pollution, improving the health and well-being of their residents.
