Creating a circular Built Environment: The why and how

Location: Buildings Pavilion (Zone C, Area 5,  lot n. 113)
Hosts: WBCSD, World Green Building Council (WorldGBC) and Arup

Time: 11:00–12:00 (EET)

Description: Approximately half of all extracted resources globally are used for the built environment, and 11% of global GHG emissions are attributed to the embodied carbon found in construction materials, with another 28% of global emissions from energy use in buildings. Simultaneously, nearly 40% of urban solid waste comes from construction and demolition. By 2025, it is expected that 2.2 billion tons of construction waste will be generated worldwide (nearly double the amount of waste in 2018).

A sustainable built environment is circular, designed for longevity, flexibility, adaptability, assembly, disassembly, reuse and recoverability, and considers future climate risks. It uses low-carbon, low-impact, non-toxic materials and it recovers used resources (materials and products on-site or from other sites). It is powered by renewable energy, ensures sustainable water consumption and enhances the wellbeing and safety of people.

The transition to a sustainable built environment requires the use of a circular economy – which demands radical, meaningful transformation centered around designing out waste, enhancing product lifecycles, and changing consumption habits. There is a need for major innovation in materials, new regulations to make circular products, net zero buildings and choices cost competitive, investment in research and innovation, a major transformation of design practices and construction materials and waste management.

Hear from key industry leaders about how they are driving business to take a systematic approach to make a sustainable built environment system a reality.
