Low-carbon and circular public procurement aims at reducing climate emissions, promoting value retention, closed material loops and savings in resource use. In the construction and renovation of buildings, attention is paid to the planning phase as well as minimizing material and demolition waste and recycling waste appropriately. In the construction of road infrastructure, significant savings in material and money could be achieved by utilizing secondary materials from the site or nearby.This study examined and illustrated the approaches of low-carbon and circular construction and their synergies and trade-offs. Emissions and potential emission savings were calculated in three case studies representing different aspects of circular construction.
