What is a Green City?

� reducing wastes & emissions� fostering re-use & recycling� Promoting the use of renewable energy� boosting housing density while expanding open space
• Environmentally friendly by:

• “Green City” embraces the essences of similar concepts, such as “Eco”, “Low-Carbon” City, to reduce the carbon footprint …
• Preparedness� Planning requirements� Infrastructure design� Shelters & resources� Public awareness
• Emergency responsiveness� reduce damage & risk incurred from disasters, accompanied with the ability to bounce back to the stable state ASAP

Why does it Matter to us?

• International financial hub fierce competition • Mass population crowdedness; set to rise in the 2-3 decadesdomestic households increase even faster• Compacted city high population, building & vehicular densities main sources of greenhouse gas emission• Coastal city vulnerable to natural attack, e.g. flooding• Climate change seasonal typhoon, tropical storm and extreme rainfall

Ageing Buildings• By 2046, private housing units aged 70 or above reach 326,000• Prone to damage due to extreme weather conditions
Climate Change• Extreme weather• More frequent extreme rainfalls• Rising sea levels• Coastal flooding risks• Risk of landslide
