As urban populations grow and as cities expand, there is need to ensure that cities can deliver not only basic services such as accommodation, transport and water but that these cities are safe, resilient and environmentally friendly.

Research suggests that globally cities occupy just 3% of earths land, but account for 75% of carbon emissions. So they are a source of global warming as well. Smart Cities need to be Carbon Friendly also. These good urban forests can very much act as carbon sinks.
