Owing to the region’s high levels of urbanisation, informal settlements and the significant amount of stock build-up, shaping a more circular built environment is key to ensuring a more resource-efficient future. A circular built environment could be created by (re)cycling demolition waste and prioritising renovations over new construction. More circular construction methods and practices, such as off-site construction, prefabrication and adopting local and sustainable materials, could also deliver sizable benefits. Increasing the energy efficiency of existing buildings, coupled with the large-scale deployment of low-carbon technologies such as photovoltaics, green roofs and heat pumps, also holds major potential.
