A green city is an urban area that is designed to be environmentally friendly and sustainable. Green cities are characterized by their use of renewable energy, efficient transportation systems, and green infrastructure. They also have a strong focus on waste reduction and recycling, which helps to reduce pollution and greenhouse gas emissions.
Some of the emerging trends in Green Cities include the use of smart growth principles to create more compact and walkable urban areas, the use of green infrastructure to manage stormwater and improve air quality, and the use of green buildings to reduce energy consumption.
