The built environment already accounts for 35-45% of global material flows and 25% of global waste generation. This leads to diverse environmental impacts in terms of climate change (grey emissions). The share of grey emissions in global greenhouse gas emissions has risen from 15% in 1995 to 23% in 2015, with the construction sector being a major emitter.

International experts from construction, architecture, urban infrastructure, and waste management fields will delve into the most promising solutions to accelerate the transition towards circular economy models, such as:

• Circular procurement in construction

• Strategies and tools of circular building design

• Material cadastres

• Low-carbon and circular building materials

• Safe use of secondary building materials

Circular Construction Conference is part of the Circon4Climate project. The project aims to limit the application of the principle of application in public procurement, the effect of the enforcer in the retail trade to secondary materials and the results of scale and scope limitations, materials to be used and solutions, for example through regional material cadastres. Action on introducing changes in the Czech Republic, Poland and Slovenia, based on a good practitioner from Germany.
