World Settlement Footprint (WSF) 3D - Material Stock - Global, 90m

Buildings provide indispensable services for human wellbeing, but their construction and use are responsible for a substantial fraction of societies’ resource requirements and greenhouse gas emissions. Mapping and quantifying the material stocks in buildings is a key research frontier in Industrial Ecology. Reliable and spatially highly resolved maps of material stocks in buildings world-wide are so far not available. Existing approaches based on nighttime light data allow large-scale coverage, but their spatial resolution is usually ~0.5-1 km. Other methods using light detection and ranging (LiDAR) and cadaster data achieve higher resolution and accuracy, but do not allow wall-to-wall mapping of large regions. Based on high-resolution Earth Observation data combined with material intensity factors (kg per m3 of building volume), we here quantify and map material stocks in buildings at the unprecedented resolution of 90 m globally. We distinguish 18 types of materials in five types of buildings. We find that global material stocks in buildings amount to 547 (391-672) Gt, approximately half of total global societal material stocks. We find highly unequal distributions of material stocks in buildings per capita and per unit area of each country. Our results agree well with previous detailed estimates of material stocks in buildings in dedicated regions or individual cities. Improved and harmonized material intensity factors emerge as a key research area for improving the accuracy of material stock maps. Our results are available as data products with high spatial and thematic resolution to facilitate future studies; e.g., of secondary resource potentials.

Purpose: The World Settlement Footprint (WSF) 3D Material Stock provides detailed quantification of the mass of different building materials used in the construction of the global building stock. This helps to quantify the ressource flow used in the contruction, maintenance and use of the building infrastructure.

Statement: The World Settlement Footprint 3D Material Stock is based on the The World Settlement Footprint 3D Volume,Height and Area Datasets in combination with the Global Human Settlement Layer (GHSL) built-up surface grid residential/non-residential classification from the

World Settlement Footprint 3D - Building Stock: The World Settlement Footprint 3D V02 - Building Volume, Height and Area 90m datasets are combined with the GHS-BUILT-S_NRES_GLOBE_R2023A urban/non-urban classification and country region specific material intensity (MI) factors.

Description: World Settlement Footprint 3D - Material Stock Processing:

Processing:

The estimation of the Material Stock is based on multiplying the building volume from the global WSF3D Volume dataset with suitable material intensity (MI) factors of kg/m³. Buildings are categorized into 5 building type categories (lightweight, residential single/multi family houses, non residential and high rise) and country/region/class specific MI factors applied.

Quality Assurance:

We assessed the robustness of the results by comparing them with other published material stock estimates and conducted a global sensitivity analysis.
