- Sustainable Buildings and Construction
DATE: Friday, June 11th
TIME: 14h - 15h30 CEST
Globally, the construction sector is one of the fastest growing and most resource intensive that exists. Land is required to extract and manufacture materials, and for new construction to be built upon. In most areas, new urban expansion is developed in the most fertile areas (IRP, 2014), thereby creating competition between land use for construction and agriculture. Twenty-five per cent of water and 12% of potable water used globally are associated with buildings (IRP 2017a; IRP 2017b), mainly for construction processes and occupation of buildings. Responsible for 39% of global GHG emissions, which are mainly associated to the operation of buildings, the conversion of land to be used for construction also contributes to biodiversity loss, deforestation and reduced carbon sequestration.
Applying a systems lens analysis to the construction value chain
The data presented above - released in the recent report by the IRP - One Planet network task force - demonstrate that the majority of both natural resource use and environmental impacts that take place along construction value chain occur at the manufacturing of construction material, the construction and the operation stages of the value chain.
And yet, although natural resource use and environmental impacts occur at the manufacturing of construction material stage, the construction stage and the operation stage of the value chain; the solutions can be found at many different stages. The interactions within the systems mean that the operations and behaviours of actors at different stages of the construction value chain can have a significant influence on the operations and behaviours of actors at other stages of the value chain.
This is a guiding principle of the value-chain approach, and will set the tone for this online discussion around how the decisions by governments and investors largely determine activity along the construction value chain. This webinar will also serve as a kick-off to a broader set of consultations with experts from the construction sector in order to present innovative business and policy solutions in order to come up with a common approach for action together.
