Build environmentally sound and carbon efficient cities.
The way we plan and design our cities now will have significant implications for how resilient, resource efficient and environmentally sound they are in the future. A green city means promoting sustainable development through a carbon efficient built environment. If new housing stock and upgraded slums fail to be the most energy efficient and sustainable as possible, cities faces multi-decade lock-in of escalating energy consumption which may aggravate economic, social and environmental challenges.
